Performance characteristics and applications of Type 1 J1939 cable

Type 1 J1939 cable is a common type of J1939 cable, and the following is its related introduction:

Appearance features

Color: Usually black.

Shape: Generally, 9-pin circular connectors are used, and the connector shape is circular, following specific size and pin layout standards.

Technical features

Electrical characteristics: Supports the 250kbit/s data transmission rate specified in SAE J1939 protocol, which can meet the communication requirements between various electronic control units of the vehicle and ensure accurate data transmission.

Compatibility: It has good compatibility with vehicle electronic systems and diagnostic equipment that comply with SAE J1939 standards, and can be easily connected to engine control units, transmission control units, instrument panels, and other devices.

Shielding performance: To reduce electromagnetic interference and signal attenuation, a shielded twisted pair structure is usually used. The metal shielding layer can effectively block external electromagnetic interference and ensure signal transmission quality.

Application scenarios

Heavy duty trucks and buses: In the electronic control system of heavy trucks and buses, Type 1 J1939 cables are used to connect the engine, gearbox, ABS system, body control system, etc., to achieve data exchange and collaborative work between various systems, such as transmitting data on vehicle speed, engine speed, oil temperature, etc.

Engineering machinery equipment, such as excavators, loaders, bulldozers, etc., can be connected to the engine control system, hydraulic system, and working device control system of the equipment to ensure precise control and efficient operation of each system during operation, such as transmitting excavation depth, hydraulic pressure, and other parameters.

Agricultural machinery: In agricultural machinery such as tractors and combine harvesters, it is used to connect control systems for sowing, fertilizing, harvesting and other operation modules, achieving automation and intelligence of agricultural operations, such as transmitting data on sowing amount, harvesting speed, etc.
