AT Machined Contacts

Copper Alloy Body, Harsh Environment, Power or Signal


Amphenol “AT” contacts were designed using existing MIL-C-39029 technology, which has long been a requirement for military procurement. These reliable, high performance contacts are ideal for use in heavy equipment for environments such as construction, mining and agricultural machinery. Contacts are nickel plated or gold plated, and are made from a high quality copper alloy. The socket utilizes a stainless steel hood to protect against probe damage. Contacts are rated for 13 Amps max current. Used typically in the Heavy Equipment market with J1939 connectors.
