Risk [Text Block] CLO Risk. The risks of investing in CLO securities include both the credit risk associated with the underlying loans combined with the risks associated with the CLO structure governing the priority of payments (and any legal and counterparty risk associated with carrying out the priority of payments). At certain times, the Fund may increase its exposure to and invest primarily in non-investment grade CLOs. A CLO’s rating does not constitute a guarantee of credit quality and it’s possible that under stressed market environments these tranches could experience substantial losses due to defaults, write-downs of the equity or other subordinated tranches, increased sensitivity to defaults due to underlying collateral default and impairment of subordinated tranches, market anticipation of defaults, and general market aversion to CLO securities as an asset class. The most common risks associated with investing in CLOs are interest rate risk, credit risk, liquidity risk, prepayment risk (i.e., the risk that in a declining interest rate period CLO tranches could be refinanced or paid off prior to their maturities and the Fund would then have to reinvest the proceeds at a lower rate), and the risk of defaults of the underlying assets.
◦Bank Loans Risk. The CLOs in which the Fund invests are typically collateralized by bank loans. Bank loans are typically originated and structured by banks and institutions on behalf of corporate borrowers. Bank loans are typically distributed by the arranging banks and private client lenders to investors primarily consisting of: CLOs; senior secured loan and high yield bond mutual funds; closed-end funds, hedge funds, banks, insurance companies and finance companies. Investments in bank loans may expose the Fund to different risks, including liquidity risk, price volatility, ability to restructure loans, credit risks and less protective loan documentation.
◦CLO Manager Risk. The Fund intends to invest in CLO securities issued by CLOs that are managed by third-party collateral managers. The Fund is dependent on the skill and expertise of such managers. CLO managers are responsible for selecting, managing, and replacing the underlying bank loans within a CLO. There can be no guarantee that any collateral manager will continue to manage such CLO through the life of the investment. Collateral managers are subject to removal or replacement by other holders of CLO securities or may voluntarily resign or may be acquired by another firm.
◦Extended Settlement Risk. CLOs purchased in the primary market (rather than from the secondary market) typically experience extended or delayed settlement periods, often longer than seven days. During the settlement window, between purchasing and settlement, these securities may be less liquid than CLOs available on the secondary market. As a result, the Fund’s ability to acquire or dispose of CLOs at a price and time the Fund deems advantageous may be impaired. In such circumstances the Fund bears a risk of loss if the value of the CLO declines before the settlement date or if the Fund is required to sell the CLO prior to settlement. There is also the risk that the security will not be issued or that the counterparty will not meet its obligation, resulting in a loss of the investment opportunity.
◦Privately Issued Securities Risk. CLO securities are generally privately-issued securities, and are normally purchased pursuant to Rule 144A or Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). Privately-issued securities typically may be resold only to qualified institutional buyers, in a privately negotiated transaction, to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund may find markets for these securities are more thinly traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value per share due to the absence of an active trading market.

Pacer Barings CLO Market Flex ETF | Currency Exchange Rate Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Currency Exchange Rate Risk. The Fund’s assets may include exposure to investments denominated in non-U.S. currencies or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Pacer Barings CLO Market Flex ETF | Derivatives Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures contracts. Derivatives typically have economic leverage inherent in their terms. Futures contracts can be highly volatile, illiquid, and difficult to value. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. A small position in futures contracts could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in futures contracts.
Pacer Barings CLO Market Flex ETF | ETF Risks Member  
Prospectus [Line Items]  
Risk [Text Block] ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods
when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Barings CLO Market Flex ETF | Fixed Income Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.
◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.
◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.
◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.
◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.
◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.
◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

Pacer Barings CLO Market Flex ETF | Floating Rate Loan Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Floating Rate Loan Risk. Floating rate loans (or bank loans) are usually rated below investment grade. The market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods. Investments in floating rate loans are typically in the form of an assignment or participation. Investors in a loan participation assume the credit risk associated with the borrower and may assume the credit risk associated with an interposed financial intermediary. Accordingly, if a lead lender becomes insolvent or a loan is foreclosed, the Fund could experience delays in receiving payments or suffer a loss. In an assignment, the Fund effectively becomes a lender under the loan agreement with the same rights and obligations as the assigning bank or other financial intermediary. Accordingly, if the loan is foreclosed, the Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, the floating rate feature of loans means that floating rate loans will not generally experience capital appreciation in a declining interest rate environment. Declines in interest rates may also increase prepayments of debt obligations and require the Fund to invest assets at lower yields. Floating rate loans are also subject to prepayment risk. Such loans may not be considered securities and, therefore, may not be afforded the protections of the federal securities laws.
◦Senior Loans Risk. The risks associated with senior loans are similar to the risks of junk bonds, although senior loans typically are senior and secured, whereas junk bonds often are subordinated and unsecured. Investments in senior loans typically are below investment grade and are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed, and such defaults could reduce the Fund’s NAV and income distributions. An economic downturn generally leads to a higher nonpayment rate, and a senior loan may lose significant value before a default occurs. There is no assurance that the liquidation of the collateral would satisfy the claims of the borrower’s obligations in the event of the non-payment of scheduled interest or principal, or that the collateral could be readily liquidated. Economic and other events (whether real or perceived) can reduce the demand for certain senior loans or senior loans generally, which may reduce market prices. Senior loans and other debt securities also are subject to the risk of price declines and to increases in
prevailing interest rates, although floating-rate debt instruments such as senior loans in which the Fund may be expected to invest are substantially less exposed to this risk than fixed-rate debt instruments. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded senior loans. Longer interest rate reset periods generally increase fluctuations in value as a result of changes in market interest rates.
◦Covenant-Lite Loan Risk. Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle. A significant portion of floating rate loans may be “covenant-lite” loans.
◦Loan Participation Risk. The Fund may not have a readily available market for loan participation interests and, in some cases, the Fund may have to dispose of such securities at a substantial discount from face value. Loan participations also involve the credit risk associated with the underlying corporate borrower.

Loan participations also involve the credit risk associated with the underlying corporate borrower.
Pacer Barings CLO Market Flex ETF | Foreign Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.
Pacer Barings CLO Market Flex ETF | Forward Currency Contracts Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Forward Currency Contracts Risk. Forward currency contracts and other currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as expected or if the Fund is unable to quickly enter or exit such contracts. The use of forward currency contracts with third parties (i.e., “counterparties”) subjects the Fund to counterparty risk, including the risk that a counterparty to these contracts becomes bankrupt, defaults on its obligations, or otherwise fails to honor its obligations. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund shares may decrease. Forward contracts require collateralization, and the commitment of a large portion of the Fund’s assets as collateral could impede portfolio management. Forward currency contracts are also subject to valuation risk, which is the risk that the contracts may be difficult to value and/or valued incorrectly.
Pacer Barings CLO Market Flex ETF | Futures Contracts Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Futures Contracts Risk. The primary risks associated with the use of futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the underlying securities or index and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) the possibility that the counterparty will default in the performance of its obligations; and (d) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it maybe disadvantageous to do so.
Pacer Barings CLO Market Flex ETF | High Yield Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block] High Yield Securities Risk. High yield debt obligations (commonly known as “junk bonds”) are speculative investments and entail greater risk of loss of principal than securities and loans that are investment grade rated because of their greater exposure to credit risk. The high yield market at times is subject to substantial volatility and high yield debt obligations may be less liquid than higher quality securities.
Pacer Barings CLO Market Flex ETF | Liquidity Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices. Trading opportunities are more limited for adjustable rate securities that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Infrequent trading of securities may also lead to an increase in their price volatility.
Pacer Barings CLO Market Flex ETF | Management Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective.
Pacer Barings CLO Market Flex ETF | Market Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. Overall market risks may affect the value of the Fund. Factors such as U.S. economic growth and market conditions, interest rate levels and political events affect the securities markets. The prices of securities held by the Fund may decline in response to certain events taking place in the U.S. and around the world, including those directly involving the companies whose securities are owned by the Fund. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. There is a risk that you may lose money by investing in the Fund.
Pacer Barings CLO Market Flex ETF | New Fund Risk Member  
Prospectus [Line Items]  
Risk [Text Block] New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares.
Pacer Barings CLO Market Flex ETF | Other Investment Companies Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above. The Fund may invest in affiliated ETFs managed by Barings and/or BIIL. Barings or BIIL may be subject to potential conflicts of interest in selecting underlying funds because the fees paid to it by certain affiliated underlying funds are higher than the fees paid by other affiliated and unaffiliated underlying funds.
Pacer Barings CLO Market Flex ETF | Privately Issued Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Privately Issued Securities Risk. The Fund may invest in privately-issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the 1933 Act (“Restricted Securities”). Restricted Securities are not publicly traded and are subject to a variety of restrictions, which limit a purchaser’s ability to acquire or resell such securities. Delay or difficulty in selling such securities may result in a loss to the Fund.

Risk [Text Block] You can lose money on your investment in the Fund.
Pacer Barings CLO Market Flex ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
Pacer Barings Secured Credit Flex ETF | CLO Risk Member  
Prospectus [Line Items]  
Risk [Text Block] CLO Risk. The risks of investing in CLO securities include both the credit risk associated with the underlying loans combined with the risks associated with the CLO structure governing the priority of payments (and any legal and counterparty risk associated with carrying out the priority of payments). At certain times, the Fund may increase its exposure to and invest primarily in non-investment grade CLOs. A CLO’s rating does not constitute a guarantee of credit quality and it’s possible that under stressed market environments these tranches could experience substantial losses due to defaults, write-downs of the equity or other subordinated tranches, increased sensitivity to defaults due to underlying collateral default and impairment of subordinated tranches, market anticipation of defaults, and general market aversion to CLO securities as an asset class. The most common risks associated with investing in CLOs are interest rate risk, credit risk, liquidity risk, prepayment risk (i.e., the risk that in a declining interest rate period CLO tranches could be refinanced or paid off prior to their maturities and the Fund would then have to reinvest the proceeds at a lower rate), and the risk of defaults of the underlying assets.
◦Bank Loans Risk. The CLOs in which the Fund invests are typically collateralized by bank loans. Bank loans are typically originated and structured by banks and institutions on behalf of corporate borrowers. Bank loans are typically distributed by the arranging banks and private client lenders to investors primarily consisting of: CLOs; senior secured loan and high yield bond mutual funds; closed-end funds, hedge funds, banks, insurance companies and finance companies. Investments in bank loans may expose the Fund to different risks, including liquidity risk, price volatility, ability to restructure loans, credit risks and less protective loan documentation.
◦CLO Manager Risk. The Fund intends to invest in CLO securities issued by CLOs that are managed by third-party collateral managers. The Fund is dependent on the skill and expertise of such managers. CLO managers are responsible for selecting, managing, and replacing the underlying bank loans within a CLO. There can be no guarantee that any collateral manager will continue to manage such CLO through the life of the investment. Collateral managers are subject to removal or replacement by other holders of CLO securities or may voluntarily resign or may be acquired by another firm.
◦Extended Settlement Risk. CLOs purchased in the primary market (rather than from the secondary market) typically experience extended or delayed settlement periods, often longer than seven days. During the settlement window, between purchasing and settlement, these securities may be less liquid than CLOs available on the secondary market. As a result, the Fund’s ability to acquire or dispose of CLOs at a price and time the Fund deems advantageous may be impaired. In such circumstances the Fund bears a risk of loss if the value of the CLO declines before the settlement date or if the Fund is required to sell the CLO prior to settlement. There is also the risk that the security will not be issued or that the counterparty will not meet its obligation, resulting in a loss of the investment opportunity.
◦Privately Issued Securities Risk. CLO securities are generally privately-issued securities, and are normally purchased pursuant to Rule 144A or Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). Privately-issued securities typically may be resold only to qualified institutional buyers, in a privately negotiated transaction, to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund may find markets for these securities are more thinly traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value per share due to the absence of an active trading market.

Risk [Text Block] Currency Exchange Rate Risk. The Fund’s assets may include exposure to investments denominated in non-U.S. currencies or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Pacer Barings Secured Credit Flex ETF | Derivatives Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures contracts. Derivatives typically have economic leverage inherent in their terms. Futures contracts can be highly volatile, illiquid, and difficult to value. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. A small position in futures contracts could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in futures contracts.

Risk [Text Block] ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the
Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.
◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Barings Secured Credit Flex ETF | Fixed Income Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.
◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.
◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.
◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.
◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.
◦Interest Rate Risk. Generally, the value of fixed income securities, as well as hybrid securities with fixed income characteristics, will change inversely with changes in interest rates. An increase in interest rates may cause the value of fixed income securities and such hybrid securities to decline. Conversely, as interest rates fall, the market value of fixed income securities and such hybrid securities tend to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.
◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

Pacer Barings Secured Credit Flex ETF | Floating Rate Loan Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Floating Rate Loan Risk. Floating rate loans (or bank loans) are usually rated below investment grade. The market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods. Investments in floating rate loans are typically in the form of an assignment or participation. Investors in a loan participation assume the credit risk associated with the borrower and may assume the credit risk associated with an interposed financial intermediary. Accordingly, if a lead lender becomes insolvent or a loan is foreclosed, the Fund could experience delays in receiving payments or suffer a loss. In an assignment, the Fund effectively becomes a lender under the loan agreement with the same rights and obligations as the assigning bank or other financial intermediary. Accordingly, if the loan is foreclosed, the Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, the floating rate feature of loans means that floating rate loans will not generally experience capital appreciation in a declining interest rate environment. Declines in interest rates may also increase prepayments of debt obligations and require the Fund to invest assets at lower yields. Floating rate loans are also subject to prepayment risk. Such loans may not be considered securities and, therefore, may not be afforded the protections of the federal securities laws.
◦Senior Loans Risk. The risks associated with senior loans are similar to the risks of junk bonds, although senior loans typically are senior and secured, whereas junk bonds often are subordinated and unsecured. Investments in senior loans typically are below investment grade and are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed, and such defaults could reduce the Fund’s NAV and income distributions. An economic downturn generally leads to a higher nonpayment rate, and a senior loan may lose significant value before a default occurs. There is no assurance that the liquidation of the collateral would satisfy the claims of the borrower’s obligations in the event of the non-payment of scheduled interest or principal, or that the collateral could be readily liquidated. Economic and other events (whether real or perceived) can reduce the demand for certain senior loans or senior loans generally, which may reduce market prices. Senior loans and other debt securities also are subject to the risk of price declines and to increases in prevailing interest rates, although floating-rate debt instruments such as senior loans in which the Fund may be expected to invest are substantially less exposed to this risk than fixed-rate debt instruments. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded senior loans. Longer interest rate reset periods generally increase fluctuations in value as a result of changes in market interest rates.
◦Covenant-Lite Loan Risk. Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle. A significant portion of floating rate loans may be “covenant-lite” loans.
◦Loan Participation Risk. The Fund may not have a readily available market for loan participation interests and, in some cases, the Fund may have to dispose of such securities at a substantial discount from face value. Loan participations also involve the credit risk associated with the underlying corporate borrower.

Risk [Text Block] Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.
Pacer Barings Secured Credit Flex ETF | Forward Currency Contracts Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Forward Currency Contracts Risk. Forward currency contracts and other currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as expected or if the Fund is unable to quickly enter or exit such contracts. The use of forward currency contracts with third parties (i.e., “counterparties”) subjects the Fund to counterparty risk, including the risk that a counterparty to these contracts becomes bankrupt, defaults on its obligations, or otherwise fails to honor its obligations. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund shares may decrease. Forward contracts require collateralization, and the commitment of a large portion of the Fund’s assets as collateral could impede portfolio management. Forward currency contracts are also subject to valuation risk, which is the risk that the contracts may be difficult to value and/or valued incorrectly.

The prices of securities held by the Fund may decline in response to certain events taking place in the U.S. and around the world, including those directly involving the companies whose securities are owned by the Fund. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions.

Risk [Text Block] Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above. The Fund may invest in affiliated ETFs managed by Barings and/or BIIL. Barings or BIIL may be subject to potential conflicts of interest in selecting underlying funds because the fees paid to it by certain affiliated underlying funds are higher than the fees paid by other affiliated and unaffiliated underlying funds.

Risk [Text Block] Privately Issued Securities Risk. The Fund may invest in privately-issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the 1933 Act (“Restricted Securities”). Restricted Securities are not publicly traded and are subject to a variety of restrictions, which limit a purchaser’s ability to acquire or resell such securities. Delay or difficulty in selling such securities may result in a loss to the Fund.
Pacer Barings Secured Credit Flex ETF | Equity Market Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Equity Market Risk. Equity securities, including preferred stocks, and hybrid securities that have equity characteristics may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Preferred stocks and hybrid securities generally are subject to more risks than debt securities because stockholders’ claims are subordinated to those of holders of debt securities upon the bankruptcy of the issuer. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
Pacer Barings Secured Credit Flex ETF | Hybrid Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Hybrid Securities Risk. Hybrid securities are subject to the risks of equity securities and debt securities. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains.

The market value of debt securities declines as interest rates rise; therefore the Fund may lose value if it sells zero coupon securities prior to their maturity date.

Risk [Text Block] Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
