AHD10-9-1939P-BP80 is a 9-position square flange receptacle connector with pin contacts designed for J1939 Type 2 diagnostic applications in heavy-duty industrial and commercial vehicles. The connector features a green thermoplastic body (UL94-VO rated), silicone rubber sealing, and a jam nut coupling system with threaded rear assembly. It supports contact size 16 with a maximum current rating of 13A at +125°C continuous operation and accommodates wire sizes from 10-20 AWG with crimp termination. The connector operates reliably across a wide temperature range of -55°C to +125°C, maintains IP67 rating in mated condition, and withstands 1500V dielectric strength with excellent corrosion resistance per MIL-STD 1344. This connector is ideal for J1939 CAN-based vehicle diagnostic systems requiring sealed, environmentally protected connections in demanding applications such as diesel engines, marine propulsion, construction equipment, and industrial power generation systems.
