Environment-Resistant Electrical Connectors, ZH23 Series
ZH23 (also referenced as CHЦ23 in Russian designation) environment-resistant electrical connectors have a bayonet coupling design with a five-key anti-mis-mating structure that helps prevent incorrect connections. They are suitable for low-frequency AC and DC circuits and are widely used in military, aerospace, and industrial automation systems that have strict requirements for electrical reliability in harsh environments.
