C&K High Reliability Connectors

High Rel Connectors

C&K’s line of high reliability connectors includes the subminiature D-Sub, the micro-D MDM/MDMA, and the single-in-line micro-strip MTB1. The high reliability connectors meet the demanding requirements of space agencies around the world by exhibiting no degassing, no magnetism, and no defects in harsh environment.

Space-ready Connectors

C&K high rel connectors are used in satellites, launchers, telescopes and other spacecraft applications (planetary, space probes…) and are qualified to ESA-ESCC, MIL-M24308 and GSFC-311P.
