Product Description:
The RHB2-022DCB cable is produced by Bosch Rexroth Indramat and belongs to the RHB2 Encoder Cables series. As a Rexroth cable, its role in industrial automation is to provide combined power and encoder transmission between MS2(x) synchronous motors and ctrlX DRIVE inverters through a direct connection topology. The basic design keeps the assembly lean while the hybrid construction reduces the number of separate lines that must be routed in a cabinet, supporting compact machine layouts and simplified installation.
In operation the copper conductors are rated for a continuous load of 15.6 A, a figure that defines the maximum permissible current before thermal limits are reached. Power conductors follow the standard of AWG 16, giving low resistive losses for typical motor distances, and the overall power cross-section is 1.5 mm², which aligns with the drive-side terminal capacity. During dynamic motion the cable must flex repeatedly; its minimum bend radius under movement is 7.5xD, and the jacket is verified for a service life of 5,000,000 cycles in energy-chain applications.
A static installation can tighten routing because the permissible fixed bend radius is only 5xD. Signal and power cores follow the manufacturer’s specified pattern of 4x L + 2x 0.75 mm² + 4x AWG 24 - DS, ensuring shielded encoder lines sit next to the power pairs inside the same sheath. Field termination is accomplished with the M23 Hybrid (SPEEDCON) plug on the motor side, while the drive end mates directly with the ctrlX DRIVE connector row, so no intermediate breakout is required. Classified as Hybrid Cables, the RHB2-022DCB merges power, signal and protective earth inside one jacket to streamline machine wiring.
