Product Description

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.

Our OBD connectors overmolded as below various design as below.  We  make OBD connector with terminal by ourselves, soldering type and crimping type are both available. Also molded by different type, straight type or right-angle type. The OBD conenctor cables used for Audi, Honda, Toyota, BWM, etc.


The J1939 OBD connectors are special for heavy-duty truck or vehicle.SAE J1939 vehicle diagnostic cables  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.

The J1939 to OBD2 Adapter Cable Type1 9 pin to 16 pin can prevent the original shunting line from the original vehicle. It is more reliable and safe to use the extension line. The plug meets the standard and RoHS requirements. It has integrated the basic diagnostic functions of J1939 heavy duty truck standard communication protocols. It has flame-retardant, precision molding, stable safety and anti-interference, tracking extension cable, perfect compatibility, new environmental protection plastic material.  J1939 to OBD2 9 pin male to female and 16 pin cable for all OBD2 interface vehicles.
