Product Description:

The Bosch Rexroth Indramat RKH0401 is a hybrid energy and signal cable belonging to the RKH Hybrid Cables series. Designed for servo applications, it combines power cores and control pairs in one sheath to simplify routing between drive controllers and motor-encoder assemblies in automated machinery. By integrating separate conductors into a single flexible line, the product reduces cabinet congestion, supports synchronized motion components, and maintains electrical separation required for reliable feedback in industrial automation cells.

The mechanical life of the cable is verified for 5,000,000 bending cycles, allowing repetitive motion axes to operate without early fatigue. Because it is cable track suitable, the jacket and filler system resist abrasion and crush loads encountered in guided chains. Electrical design follows a mixed-core layout of 5×2.5 + 5×0.34 + (2×2×0.34) mm², supplying three-phase power, auxiliary voltage and differential signals within one round profile. The two power circuits can carry continuous currents of 2×25 A and 2×15 A, supporting medium-frame servo motors while limiting temperature rise. Despite this capacity, the assembly maintains a compact 16.2 mm outer diameter, aiding installation in densely packed machine enclosures.

Dimensional consistency is held to a ±0.5 mm diameter tolerance, so clamping elements maintain uniform strain relief after the dynamic duty described earlier. A rugged PUR jacket supplies oil, coolant and microbe resistance while preserving flexibility; it also meets halogen- and silicone-free requirements for paint shops. For modular system wiring, the factory-installed REH0800 inline coupler mates the motor side to extension segments, linking a RHS0001/C03 right-end connector with the complementary RHS0005/C03 plug on the drive end. Minimum bend radii of 5 × AD when fixed and 10 × AD during motion further coordinate with chain layout to prevent conductor deformation.
