The Bosch Rexroth Indramat RKH0220 is a ready-made hybrid cable from the RKH Hybrid Cables series with a basic cable design. It features RHS0021 connectors at both ends, supports up to 5,000,000 bending cycles, and has a dynamic bending radius of 8xD and a static bending radius of 4xD. The cable operates in temperatures ranging from -40 to 80 degrees Celsius and uses the REH0803 raw cable variant.

Product Description:
The RKH0220 hybrid cable is manufactured by Bosch Rexroth Indramat as part of the RKH Hybrid Cables series. This component combines power and signal conductors in one sheath so drive controllers can be linked to servo motors with fewer individual leads and shorter installation times inside automated machinery.
The cable is supplied as a Ready-Made assembly, meaning it arrives cut to length and terminated, eliminating on-site crimping or soldering. Its service life is qualified for 5,000,000 continuous flex cycles, a figure suited to energy-chain or robotic axes that move every production cycle. Flexibility is protected by a dynamic bending radius of 8xD; when the cable is routed through moving carriers the inner conductors stay below their mechanical strain limit if this minimum radius is observed. In static routing, the permissible bend tightens to 4xD, which saves cabinet space without affecting reliability. Both cable ends use the compact bayonet connector type RHS0021, allowing fast, tool-free mating with IndraDrive power modules and motor feedback ports.
This variant is classified as Hybrid; power cores and digital feedback pairs share a common jacket to minimise electromagnetic coupling paths. Internally, the conductors are built from the REH-series raw material, identified here as REH0803, which provides a finely stranded copper bundle and an abrasion-resistant PUR outer jacket. Thermal ratings extend to 80 °C during operation, while the minimum service temperature reaches -40 °C, allowing installation in refrigerated or outdoor equipment. Identical upper and lower limits apply for storage, so spare lengths can be kept in the same warehouse climate where machines are assembled. The basic cable design omits additional shielding layers, reducing diameter and weight for cable-track layouts that already meet EMC requirements.
