QLS

QLS

The 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 advantge of allowing a time-saving connection without the need for any tooling. This locking mechanism also guarantees an extremely high butt contact force on the outer conductor, which is normally only achieved with a threaded coupling mechansim. This high contact force results in excellent coupling reliability, even under mechanical stress such as vibration or due to the attached cable being pulled. The QLS® connectors are 100% compatible with QMA connectors.
