Amphenol Industrial Solar AT Circular Connectors

AT Circular (ATC) thermoplastic upgraded connectors mate with a positive reverse bayonet retention system and can handle current up to 13 A. Sealed and rated to 125C, Amphenol's ATC connectors are ideal for communication and diagnostic testing in heavy-duty trucks, buses, and construction and agricultural equipment. Available in 3-, 5- and 9-way receptacles, these connectors are drop-in replacements for existing panel designs. The 9-way receptacles are also available with a jam nut for quick assembly.

Amphenol's ATC reverse bayonet coupling design allows for quick mating and unmating. These corrosion resistant, heavy-duty industrial connectors are environmentally sealed against both moisture and contaminants. Durable to 100 mating cycles, the connector's contact retention system helps reduce installation costs and increase reliability.
