Product Description:
The RKL4731 is a flexible motor power cable produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It carries three-phase energy from drive amplifiers to servo motors and includes smaller control cores so feedback devices can share the same routed bundle. By combining power and auxiliary conductors in one factory-terminated assembly, the cable simplifies machine wiring and shortens installation time on automated axes.
This model is supplied as a Ready-Made Power Cable that arrives cut to length with mating ends already attached. The motor side terminates in a RLK1401 clamp box, while the drive side uses a RLS0721 plug connector; these keyed interfaces prevent polarity errors during maintenance. Four power conductors sized at 4x6.0 mm² carry the main phase current, and two signal pairs sized at 2 × 1.0 mm² + 2 × 1.5 mm² support brake release or temperature sensors without needing a separate harness.
The mechanical design withstands 5 million bending cycles, making the cable suitable for constantly moving drag-chain applications. Dynamic motion is permitted down to a bend of 7.5 × D dynamic radius, while stationary runs may be formed as tight as 5 × D static radius without degrading insulation. A PUR jacket resists cutting fluids and abrasives and is molded in orange (RAL 2003) for quick identification inside control cabinets. The total braid and foil arrangement provides a “Total Shield” that blocks conducted noise from inverter switching, helping servo feedback remain stable on long machine runs.
