AT Series™ Bulkhead Receptacles

Amphenol Sine Systems AT Series™ Bulkhead Receptacles combine a robust, easy-to-mount, sealed housing with the benefits of AT Series (13A) connectors. This requires less operating space while allowing higher-density installation. Available in a 4 X 12 (48-position) configuration, the modules are individually keyed and color-coded to prevent mismating. The series offers the ability to attach from the front side of a device and securely lock it for high resistance to vibration and increased design flexibility. These Amphenol Sine Systems receptacles are IP68/69K rated when mated.
