Amphenol Industrial AT circular connector series

The Amphenol Industrial operations’ AT circular series is a robust, environmentally sealed connector solution designed for heavy-duty applications in construction, agriculture, trucking, industrial controls, and transportation.

These connectors feature a thermoplastic shell with a reverse bayonet coupling mechanism for quick and secure mating. Available in jam nut (no screws required) and square flange mounting styles, the series offers easy installation with optional strain relief for enhanced durability. Additionally, an optional cap and lanyard are available to protect the connectors when not in use, ensuring long-term performance in harsh environments. The 9-pin black receptacle aligns with the J1939 diagnostic connector interface, ensuring compatibility with vehicle data communication systems.

Utilizing AT contact technology, these connectors incorporate machined contacts with Nickel or Gold plating, delivering superior conductivity and long-term performance. The series is RoHS compliant, designed to withstand harsh environments by sealing against moisture and contaminants, while the contact retention system increases reliability and reduces installation costs.

With multiple layout configurations (available in 3, 5, 6, and 9 contacts) the AT Circular Series provides a durable and costeffective interconnect solution for demanding applications.
