Product Description:
The RKH0311 cable assembly is manufactured by Bosch Rexroth Indramat as part of the RKH Hybrid Cables series. It is a hybrid lead that carries both motor power and encoder feedback in a single sheath, allowing compact routing between IndraDrive controllers and synchronous motors in automated machinery. By merging functions that otherwise require two separate cables, the product simplifies installation and reduces cabinet space in industrial motion systems.
For continuously moving cable tracks, the RKH0311 is specified for 5,000,000 bending cycles, indicating the number of flex events it can withstand before conductor fatigue is expected. During dynamic motion, the manufacturer permits a minimum bend radius of 10xD, while stationary runs can be laid with a tighter 5xD radius; “D” references the cable’s outer diameter and defines the curvature that avoids internal stress. The permitted operating envelope extends from -40 °C up to 80 °C, so the polymer jacket and insulation remain stable in cold-start situations and in cabinets where elevated ambient heat is present. These limits establish the mechanical and thermal boundaries that system designers must observe when specifying drag-chain lengths, acceleration profiles, and enclosure ventilation.
Complementing those endurance figures, the RKH0311 is built on the Basic cable model and is delivered as a Ready-Made assembly, eliminating the need for on-site termination. A moulded RHS plug set is fitted at each end: drive-side connections use the RHS0005 interface and motor-side connections use the RHS0011 interface, providing keyed locking and strain relief for high-cycle motion. Internally, the conductors follow the REH0800 raw cable design and apply the hybrid cable variant’s power-plus-signal core arrangement, ensuring impedance balance for encoder channels while maintaining current capacity for servo phases.
