Features smaller flange
23 September 2014
Amphenol Industrial Products Group has enhanced its 9-way AT circular series receptacle line by adding a smaller flange version that can be fitted to all heavy equipment vehicles. The ATC-09-9-1939PN meets SAE J1939, a specification for communication and diagnostics among industrial vehicle components.

These round receptacles include a strain relief for the wires coming out of the back of each unit and a wave spring for higher vibration applications. The enhanced heavy duty connectors feature a simple jam nut mounting for quick assembly and a smaller flange to save space on mating panels. They are corrosion resistant and environmentally sealed against moisture and contaminants as well as being water resistant up to three feet. An optional sealing cap for mating interface is also available.
The receptacles offer a reverse bayonet coupling design for quick mating and unmating. Easily withstanding more than 100 mating cycles, the connector’s contact retention system helps decrease installation costs and increase reliability. The RoHS-compliant connectors work with industry standard size 16 contacts and are made from high quality copper alloy, with nickel and gold plating available. They have an operating temperature range of -55°C to +125°C.
