Product features of 9-pin J1939 Type 1 black connector to Type 2 J1939 green cable

The product features of connecting the 9-pin J1939 Type 1 black connector to the Type 2 J1939 green cable mainly include connector compatibility, electrical performance, durability, and environmental adaptability. The following is a specific analysis:

Connector compatibility

Pin adaptation: The connection between the 9-pin J1939 Type 1 black connector and the Type 2 J1939 green cable requires precise matching of pin definitions and electrical parameters. The J1939 protocol specifies the types, pin assignments, and electrical characteristics of connectors, and this connection method must comply with relevant standards to ensure accurate signal transmission.

Connector type: J1939 This type of connector has good reliability and stability. The connection between type 1 black connector and type 2 green cable maintains consistency in connector type, which helps to achieve stable physical connection.

Electrical performance

Impedance matching: The characteristic impedance of J1939 bus is 120 Ω. This connection product needs to ensure impedance matching at the connection point to reduce signal reflection and interference, and ensure the accuracy of data transmission.

Signal transmission rate: The J1939 protocol typically supports a communication rate of 250Kbps, and this connection product should be able to meet this rate requirement to ensure fast and stable signal transmission.

Insulation and conductivity: Cables and connectors should have good insulation performance to prevent leakage and short circuits. At the same time, the connector contacts should have good conductivity to ensure the stability of electrical components.

Durability and reliability

Shell material: The product shell is made of high toughness, high temperature resistant flame retardant material, which has good smoothness and hardness stability, and can withstand certain mechanical impacts and vibrations, extending the service life.

Sealing design: It may be equipped with sealing devices such as rubber rings to prevent water and dust, improving the applicability of the product in harsh environments.

Environmental adaptability

Temperature range: Able to operate normally within a wide temperature range and adapt to different working environments.

Electromagnetic compatibility: It has good resistance to electromagnetic interference and can work stably in complex electromagnetic environments, reducing the interference of external electromagnetic fields on signal transmission.
