AHDC-16-9-BLK is a 9-position circular thermoplastic connector from the AHD Series designed for diagnostic and data communication applications requiring J1939 Type 1 compliance. The connector features contact size 16 with a maximum current rating of 13A at +125°C continuous operation and a voltage rating of 250V, housed in a black thermoplastic body (UL94-VO) with silicone rubber sealing for environmental protection. It incorporates a coupling ring mechanism, standard diameter rear seal, and threaded rear assembly, delivering IP67 protection in mated condition with operating temperatures from -55°C to +125°C. The connector supports crimp termination with copper alloy gold-plated contacts and maintains durability through over 500 mating cycles and 100 engagement/disengagement cycles, making it ideal for heavy-duty industrial vehicle diagnostic systems and J1939-compliant communication networks.
