The ZH23 series electrical connectors are specifically designed for low-frequency AC/DC circuits. They feature environmental resistance, five-key positioning to prevent incorrect insertion, quick snap-on connection, and the contact components adopt a compression-type, later-release structure.
Choosing the ZH23 series means obtaining a proven connection solution that is both compatible with Russian standards and reliable according to Chinese standards, and is suitable for scenarios with extreme environments, high vibration, the need for anti-insertion protection, and the requirement for quick maintenance. It is particularly suitable for key areas such as avionics equipment, military communication systems, field engineering equipment, and shipborne radars.
