The AT04-3P Rectangular Socket consists of a thermoplastic housing and metal contact pins arranged in a three-pin configuration. The housing provides insulation and protection against environmental factors, while the metal contacts ensure efficient electrical conductivity. The socket is designed to mate with compatible plugs, creating a secure and stable connection. When a plug is inserted, the metal contacts within the socket align with the plug's pins, establishing an electrical circuit. The robust design prevents misalignment and ensures consistent performance, even in high-vibration environments. The socket's rectangular shape also aids in easy installation and alignment in panel mounts or equipment enclosures.
