Product Description:
The RHB2-521DCB cable is produced by Bosch Rexroth Indramat and belongs to the RHB2 Encoder Cables series. As a Rexroth cable for industrial automation, it carries both encoder signals and motor power between MS2 synchronous servomotors and ctrlX DRIVE inverters, providing a single-run alternative to separate feedback and power lines in dynamic motion axes.
This model is specified for 5,000,000 bending cycles, indicating suitability for energy-chain or robot applications that move continuously. Its conductor set follows the layout 4x L + 2x 0.75 mm² + 4x AWG 24 – DS, combining power, brake, and differential signal pairs within one sheath. The core classification as Hybrid Cables means power and encoder elements share the same jacket, reducing installation time. Each power core has a cross-section of 1.5 mm², balancing voltage drop with flexibility. During motion, the cable must observe a minimum dynamic bend of 7.5×D; once fixed, the static radius can shrink to 5×D without stressing the insulation system.
Fast machine wiring is enabled by the SPEEDCON locking system, allowing quarter-turn mating on the factory floor. On the motor side an M23 hybrid connector transfers three-phase supply, brake, and digital feedback through a single interface, matching the Plug S variant on MS2x motors. The drive-side connector mates directly with ctrlX DRIVE modules listed under series connection 2, while series connection 1 references MS2(x) stator families. The cable keeps a basic design classification, meaning no special drag-chain reinforcements are added beyond the standard PUR jacket.
Wake Industrial offers a 1-year warranty on each cable, can arrange international shipping options, and provides a free chat tool for general questions about part numbers or fault codes.
