Amphenol Sine Systems DuraMate™ AHDP Circular Plastic Connectors

Amphenol Sine Systems DuraMate™ AHDP Circular Plastic Connectors are environmentally sealed, heavy-duty, circular connectors. This series provides an economical, quick-connect, bayonet locking system that is manufactured to withstand the challenges and complexities of off-road harsh environment applications. These connectors are available in size 24 with 13 insert arrangements and in size 18 with 6 insert arrangements. The connectors feature an easy-grip coupling system with visual and tactile indicators that ensure reliable mating confirmation. Two different backshell systems thread onto the rear of the connectors to provide strain relief and additional wire seal protection. Amphenol Sine Systems DuraMate AHDP connectors offer IP68 / IP69K protection (in mated condition) from dust, water, mud, and other contaminants. The AHDP components are ideal for panel-mount or in-line heavy-duty applications such as commercial vehicles, agriculture, construction, and marine installations.
