Product Description:
The RKH0904 belongs to the RKH Hybrid Cables series manufactured by Bosch Rexroth Indramat. It is a pre-assembled hybrid cable intended to combine motor power conductors with encoder or sensor lines inside one jacket, reducing cabinet wiring and assembly time in industrial automation systems. Used between servo drives and moving axes, the cable supports coordinated motion while limiting electromagnetic interference and maintaining mechanical flexibility needed in cable chains.
The assembly is supplied as a Ready-Made cable, so terminations are already crimped and factory tested for continuity. Its flex-rated jacket endures up to 5,000,000 repetitive bend cycles, a value relevant for gantry robots or linear modules that travel continuously. During motion, the conductors can flex down to a dynamic radius of 10xD, while static routing—for example inside a cabinet door—may be set to a minimum radius of 5xD. Power and signal cores are consolidated into an RHS-type plug at the drive end; the interface specified for that side is the keyed circular connector RHS2321, ensuring correct mating and strain relief in tight spaces.
The opposite machine-side plug is the hybrid receptacle RHS0011, allowing quick motor exchange without individual pin handling. Because the build is a Hybrid Cable, separate servo and feedback harnesses are unnecessary, which decreases total chain weight and reduces potential points of failure. The cable follows the manufacturer’s Basic design classification, meaning the outer jacket uses a standard polyurethane blend suitable for normal oil-mist factory environments. Long service life is achieved through conductor pairing, optimized twist lengths, and the materials selected by Bosch Rexroth Indramat for vibration-prone axes that must remain electrically stable over thousands of production hours.
