What types of connectors are used in conjunction with J1939 cables?

The common types of connectors used in conjunction with J1939 cables are as follows:

Deutsch connector

Deutsch HD10 connector: circular in shape, can be used to connect devices that comply with J1939 standards, providing reliable electrical connections and mechanical stability, can adapt to harsh environments, and is commonly used in heavy vehicles and industrial equipment.

Deutsch DTM connector: rectangular in shape, with good sealing and vibration resistance, ensuring stable communication in environments such as vibration, dust, and humidity, suitable for connecting various electronic control units and sensors.

9-pin circular connector

Type 1 black connector: It is a common type in J1939 systems, with a 9-pin layout following specific functional definitions, used to transmit signals of J1939 protocol, including power, ground, CAN communication signals, etc. It is generally used in commercial vehicles before 2015.

Type 2 green connector: There are differences in physical size and some functions compared to Type 1, with a communication rate of up to 500kbs. It is mainly used for new commercial vehicles in 2016 and beyond to meet higher data transmission requirements.

Y-shaped connector: Used for branching connections, it can distribute a J1939 interface signal to two or more devices, facilitating the simultaneous connection of multiple diagnostic tools, monitoring devices, or other electronic control units, achieving multi-faceted monitoring and control of vehicles or equipment.

Conversion connector

Male female adapter: Used to connect devices or cables with male and female interfaces, enabling adaptation between different interface forms.

Different communication rate conversion connectors: such as converting a 250kbs J1939 signal to a 500kbs rate, or vice versa, to meet the communication rate requirements of different devices.

Different physical interface conversion connectors: For example, converting the 9-pin circular interface of J1939 to other types of interfaces, such as OBD-II interface, for easy connection with other systems or devices.
