Cable assembly manufacturer Semflex Inc. has developed a new cable assembly series for military and aerospace applications equipped with self-locking ZMA coaxial connectors. The self-locking mechanism feature of this bayonet-type connector eliminates the axial movement normally found in BNC connectors while retaining the BNC's easy quarter-turn installation characteristic. The ZMA offers significant advantages in high vibration environments by giving the connector the mechanical stability of a threaded coupling nut. The quarter-turn mating is highly beneficial where connector density is high and/or installation space is minimal.“By combining the ease of installation of the BNC with the stability of threaded connectors, our new ZMA-terminated cable assemblies enable higher installation and maintenance efficiency and delivers improved high-frequency performance,” said Doug Hartje, vice president of sales for Semflex. The ZMA improves phase noise performance and achieves a 10-dB improvement in RF shielding by eliminating interface misalignment typically caused by cable weight down force on the connector back shell end. The ZMA also delivers a more reliable signal path in harsh shock and vibration environments.Connectors may be keyed with three and four lug patterns to create distinct mating patterns for each signal path. Outer construction is passivated stainless steel. Integrated silicone gaskets seal out moisture when the ZMA is in mated position. Operating temperature range is -65°C to +200°C.
