CAN Bus Cable Assembly

Every multi-axis robot relies on a CAN bus backbone to coordinate servo drives, safety controllers, I/O modules, and sensor nodes across a single twisted-pair network. A single impedance mismatch or shield break anywhere on that bus drops packets, triggers fault codes, and stops production. Our CAN bus cable assemblies are engineered from the conductor pair outward to maintain 120Ω ±10% characteristic impedance across the full operating frequency range — from CAN 2.0 at 1 Mbps through CAN FD at 8 Mbps. We build complete bus segments with factory-terminated connectors, integrated 120Ω termination resistors where specified, and continuous-flex PUR jackets rated for 10 million+ bend cycles in drag-chain and torsion applications. Each assembly ships 100% TDR-verified for impedance continuity and electrically tested for conductor resistance, insulation resistance, and shield coverage. From 2-node point-to-point links to 64-node distributed bus architectures, we deliver CAN cabling that keeps your robot cells communicating without a single retransmission. Compatible with FANUC, ABB, KUKA, Yaskawa, Siemens, Beckhoff, and Omron platforms running CANopen, DeviceNet, J1939, or proprietary CAN protocols.
