RKB0006 by Bosch Rexroth Indramat

The RKB0006 cable is produced by Bosch Rexroth Indramat within the RKB Control Cables series. It is a sensor-actuator interconnect assembled at the factory and delivered in finished lengths for immediate installation inside automated machinery. The cable's function is to transmit control signals between distributed sensors, valves, and a central motion controller, allowing field devices to exchange position or status data with drive electronics without additional on-site termination. Its finished construction helps maintain consistent signal routing where machine wiring must pass through moving assemblies or confined cabinet spaces.

RKB0006 is categorized under the basic model class, indicating a standard insulation and shielding arrangement for plant environments. Its test record of 5,000,000 cycles indicates the number of flex motions it can endure in cable-chain applications. Because it is a Ready-Made assembly, it does not require crimping or tinning of individual cores before use. The product is a Sensor-Actuator Cable, so every core is sized for low-level control currents rather than motor power. On the device side, an M12 8-pin circular connector provides quick-lock coupling to proximity switches or miniature valves. During continuous motion, bending must stay above a dynamic radius of 7.5xD, where D is the outer diameter, to help prevent jacket cracking.

The fixed portions of the installation use a permitted static radius of 5xD, which supports tight routing inside control cabinets while maintaining conductor integrity. Field connection toward the controller is handled by a 9-pin D-Sub connector, which allows direct attachment to legacy I/O boards that still rely on the subminiature interface. Storage is permitted from -30 °C to 40 °C, helping protect the dielectric materials against embrittlement or thermal creep while the cable is kept in inventory before use or transported between storage and installation areas.
