Product Description:

The RKH0301 is a hybrid power-and-signal cable produced by Bosch Rexroth Indramat for the RKH Hybrid Cables series. It links servo drives to moving actuators in automated machinery, combining motor conductors, control pairs, and encoder lines inside a single sheath so cabinet wiring remains compact while drag-chain motion remains reliable.

The flex life reaches 5,000,000 bending cycles, a rating that defines how often the cable can move in an energy chain before conductor fatigue becomes critical. A sheath of PUR resists oil, coolant, and abrasion, and it encloses a composite core specified as 5x2.5 + 5x0.34 + (2x2x0.34) mm²; these cross-sections separate motor phases, auxiliary power, and twisted signal pairs to minimise crosstalk. The drive-side Kcu plug is the keyed RHS0005/C03, allowing direct connection to Indramat inverters, and the total diameter remains 16.2 mm, which determines gland size and chain fill factor.

On the motor side, the Ksm interface is the compact RHS0001/C03 so installation time is shortened and pin assignment stays consistent across the series. Continuous operation is permitted up to 40 °C, while warehouse storage can reach 60 °C without degrading insulation. Dynamic routing requires a minimum bend radius of 162 mm; when the cable is fixed, 81 mm is sufficient, helping designers size cable carriers correctly.
