MW Series MIL-DTL-55181 Connectors

Amphenol PCD MW Series MIL-DTL-55181 Connectors are ideal for military and harsh environments. The waterproof and polarized connectors feature a center lock coupling screw, ensuring the ability to withstand high shock and vibration. These connectors require minimal finger space for mating, allowing closer board configuration than other mil-spec connectors. Amphenol PCD MW Series connectors are typically used for the interconnection of power and control, including military communication equipment and ground vehicles.
