QLS®


The QLS® (Quick Lock Standard) connector family features similiar interface dimensions like the SMA connector family. The only difference is that instead of a threaded coupling, a quick lock mechanism is being used.

This connector family is suitable for the standard ranges of flexible and semi rigid cables and is also available in PCB and panel mount versions. 

With the characteristic impedance of 50 ohm, the return loss of QLS® coaxial connectors is optimised for frequencies up to 18 GHz.
