SAE J1939 OBD diagnostic connectors

The heavy-duty J1939 cables are used for interfacing with CAN (Controller Area Network) bus signals on a variety of machinery and vehicles. The CAN bus is engineered to permit microcontrollers and devices to openly communicate without the existence of a host computer. Widely adopted by the diesel engine manufacturing industry to help interface with Electronic Control Units (ECU).

Now J1939 connectors are available by green, grey and black color, also with different locking type for assembling.

The J1939 OBD connectors are special for heavy-duty truck or vehicle. SAE J1939 cable can be found in a number of diesel powered applications including diesel trucks, buses, on-road vehicles, off-road vehicles, marine propulsion, power generation, and industrial pumping. In the automotive industry the ECU can handle a variety of subsystems throughout the vehicle with the largest being the engine control unit and others including transmission, airbags, antilock brakes/ABS, cruise control, and more. Your J1939 custom cable will provide a solid and reliable connection to your specific CAN bus delivering communication and diagnostic data from multiple Electronic Control Units (ECU).
