DataCELL J1939 CAN bus cables from Northwire are designed to meet and exceed the SAE J1939/11 specification. The cables offer high quality and cost less than competitive cables. They come in two grades. The J1939CR has a high-performance elastomer construction for extra cut resistance, and the J1939TR has a tough, waterproof TPR jacket. Both are easier to pull and strip for increased productivity and have high velocity of propagation for more consistent levels of impedance and capacitance.
