Amphenol Industrial Products Group introduces a series of thermoplastic receptacles featuring Amphenol's AT contact technology. This series is designed to perform in the demanding applications found on construction and farm equipment, as well as truck environments. The AT circular series is a molded thermoplastic receptacle with a positive reverse bayonet retention system and sealed by redundant grommet wire sealing. The square flange design ensures a drop-in replacement to existing panel designs and the jam nut version makes for easy installation. The 9-pin black receptacles are in accordance with the interface of the J1939 diagnostic connector. AT contact technology is already used successfully at major OEMs and features machined contacts with both nickel and gold plating.
