QLS®: Contact Reliability in Push-Pull Technology

The RF connector series QLS (Quick-Lock-Standard) is a secure and reliable alternative to standard SMA connectors. The patented locking mechanism of the QLS series gives it the distinct advantage of allowing a time-saving conntection without the need for any tooling.



The Quick Lock Standard guarantees an extremely high butt contact force on the outer conductor, which is normally only achieved with a threaded coupling mechanism. This high contact force results in excellent coupling reliablity, even under mechanical stress such as vibration or due to the attached cable being pulled. The QLS connectors are 100 % compatible with QMA connectors.

  • Quicker to engage due to Push-Pull mechanism (self-locking)

  • Higher packaging density, since tooling is not required

  • No requirement for torque spanner for high, defined contact force


  • Higher contact force (QLS: 200 N, QMA: 60 N)

  • Better electrical characteristics (intermodulation, return loss, contact reliability)

  • Higher mating cycles (QLS: 200, QMA: 100)

  • Accidental disconnection by pulling on the attached cable practically impossible
