RKB0062 by Bosch Rexroth Indramat

The RKB0062 cable is produced by Bosch Rexroth Indramat within the RKB Control Cables series. It is a ready-made industrial Ethernet line intended to connect drives, PLCs, and decentralized I/O modules inside automated cells. Because it is preassembled with application-specific plugs, the cable can be routed immediately without field termination, which helps save panel space and reduce wiring mistakes. In motion systems, it acts as the physical layer for deterministic network protocols that synchronize axes, collect sensor data, and forward status information to supervisory equipment.

It is rated for 5,000,000 bending cycles, indicating that the conductor insulation and braided shield can flex five million times in an energy chain before fatigue occurs. During operation, the cable may be curved down to a 7.5×D dynamic bending radius, while permanent routing permits a tighter 5×D static bending radius. The cable operates from −30 °C minimum temperature up to 80 °C maximum temperature, so it can be used in cold-start machines as well as cabinets with elevated ambient heat. The assembly is supplied as a ready-made length, which removes on-site cutting and helps maintain continuous 360-degree shielding through the factory-crimped connections.

The cable terminates in a Mini I/O I interface at one end and a Mini I/O II interface at the other, matching the compact board connectors used on Rexroth control hardware. Classified as an Ethernet variant, the pair-balanced conductor geometry meets CAT5 Ethernet category requirements for impedance, crosstalk, and propagation delay, allowing reliable 100 Mbit/s real-time traffic inside moving machine axes. Shield continuity is carried through the overmolded backshells so electromagnetic interference picked up along the drag chain is drained to ground. This supports stable data transmission during repeated motion while keeping the cable suitable for compact control connections.
