Physical characteristics and environmental adaptability of J1939 to J1708 cable

physical property

Interface type and size: J1939 and J1708 interfaces have different shapes, pin definitions, and sizes. It is necessary to ensure that the cable interface matches the interface on the device completely, including the shape of the interface, the number and arrangement of pins, etc., to ensure the stability and conductivity of the connection.

Cable length: Choose the appropriate length of cable based on the distance between devices in actual usage scenarios, and avoid being too long or too short. Too long may cause signal attenuation, while too short may not meet connection requirements. If unsure, you can choose a slightly longer cable and organize it properly to avoid situations where the length is insufficient.

Flexibility and hardness: Choose cables with appropriate flexibility or hardness based on the usage environment and installation method of the cable. In situations where frequent movement or bending is required, flexible cables should be selected to facilitate operation and avoid damage; In some places that require fixation and high protection requirements, cables with higher hardness and certain protective performance can be selected.

Environmental adaptability

Temperature range: Considering the temperature variation range of the cable usage environment, select cables that can work normally within this temperature range. For example, in high-temperature industrial environments or cold outdoor environments, it is necessary to choose cables with corresponding high temperature or cold resistance performance to prevent cable performance degradation or damage.

Corrosion resistance: If the cable may come into contact with corrosive media such as oil, water, chemicals, etc., it is necessary to choose cables with good corrosion resistance, such as cables with special coatings or sheath materials, to extend the service life of the cable.

Mechanical strength: In environments that may be subjected to mechanical stress, friction, or compression, cables with sufficient mechanical strength should be selected, such as reinforced cables or cables with protective covers, to prevent damage to the cables due to external forces.
