The Bosch Rexroth Indramat RKH0903 is a basic hybrid cable from the RKH Hybrid Cables series with a length of 5.0 meters. It features a dynamic bending radius of 10 times the diameter, static bending radius of 5 times the diameter, and supports up to 5,000,000 bending cycles. The cable operates between -40 and 80 degrees Celsius and uses RHS0005 and RHS2321 connectors.

Product Description:
The RKH0903 is a hybrid power-and-signal cable manufactured by Bosch Rexroth Indramat within the RKH Hybrid Cables series. It links IndraDrive servo axes to controllers through a single jacket that carries energy conductors alongside digital feedback pairs, reducing cabinet wiring and installation time in automated machining centers and material-handling systems.
Mechanically the cable is qualified for 5,000,000 cycles of continuous flexing in drag-chain applications, so it withstands long service in high-duty production lines. A factory-terminated length of 5.0 m suits typical axis-to-cabinet runs without excess slack. Dynamic motion is governed by a minimum bend radius of 10xD, while static installations may tighten to 5xD; these ratios help installers prevent conductor fatigue and preserve shielding integrity. The hybrid construction merges motor phases, encoder cores, and protective earth within one sheath, which simplifies routing through confined energy chains.
Environmental limits span -40 °C to 80 °C for both operation and storage, allowing the assembly to travel unconditioned between staging areas and function inside heated enclosures. Factory-molded connectors – the drive-side RHS0005 and the motor-side RHS2321 – lock with bayonet threads to maintain vibration-proof contact. The Basic design keeps outer diameter moderate, and the declared hybrid variant avoids separate feedback cables, trimming machine weight and assembly time. Together these attributes complement the flex-life and radius data by guaranteeing reliable signal integrity across moving axes.
Wake Industrial can arrange same-day shipping when the cable is required quickly. A 1-year warranty covers each unit against manufacturing defects. Quotations remain valid for 30 days, allowing planners to align purchase orders with maintenance schedules.
