Product Description:

The RL2-023CBB motor power cable is produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It belongs to the Rexroth Cable product group and links second-generation IndraDrive servo amplifiers to matched motors in automated assembly stations, gantry loaders, and packaging lines. By combining power conductors and auxiliary cores within one jacket, the cable carries motor current and support circuits through moving cable paths. The assembly is intended for industrial use where motion and routing space are both limited.

Its internal layout follows the 4 x L + 4 x 0.75 mm² design, with four main cores for motor phases and four smaller conductors for brake release or sensor circuits. Each phase conductor has a cross-section of 1.0 mm², which provides sufficient ampacity for low-power axes and helps limit voltage drop over several meters. During continuous motion, the cable withstands a flex life of 5,000,000 bending cycles under repetitive machine travel. Mechanical stress is controlled by a dynamic bending radius of 7.5 × D, and the motor end is terminated with an M23 Power Connector for keyed, secure mating. This combination supports reliable routing in cable carriers that cycle throughout normal machine operation.

For parked or infrequent-motion sections, the cable can be laid with a static bending radius of 5 × D, which makes installation easier in compact control cabinets and fixed routing areas. Thermal endurance supports a wide operating range, and the conductor insulation remains stable from -30 °C to 80 °C. The cable is compatible with 2nd motor generation systems, so its shielding and electrical layout match the intended Rexroth servo arrangement. It also uses a basic jacket construction and a tinned-copper braid to protect the conductors and maintain stable electrical transmission during repeated motion.
