Amphenol Sine AT Series 48 Position Bulkhead Receptacles

The AT Series™ Bulkhead Receptacle combines a robust, easy to mount IP67 sealed housing with the benefits of AT Series (13A) connectors requiring less operating space, allowing higher density installation. Available in a 4 X 12 (48 Pos) configuration, each connector module is individually keyed, and color coded to prevent mis-mating. Suitable for a wide range of applications with the ability to attach from the front side of device and secure locking with high resistance to vibrations offers increased design flexibility.

The AT Series connector design incorporates an integral latching system that ensures a definitive electrical and mechanical connection. Connector housings are manufactured with a durable, UV resistant, thermoplastic material with dielectric/mechanical properties and environmentally RoHS compliant. The sealing system is comprised of front and rear silicone seals, multi-sealing perimeter against environmental ingress. Contacts are derived from quality copper alloy to ensure an electrically-reliable connection.
