Product Description:
The RL2-147KBB is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It is intended to connect a drive controller to the C-type M50 terminal box on a servo motor, supplying three-phase power and auxiliary conductors to moving axes in automated machinery. By housing the required conductors in a single flexible assembly, the cable simplifies routing through drag chains and maintains reliable energy delivery for conveyors, gantries, and other motion platforms. This arrangement also reduces the number of separate cable runs needed between the drive and motor.
The copper cores have a cross-sectional area of 25.0 mm², which helps limit resistive losses over extended runs. The insulation system for the power conductors supports up to 600/1000 V, matching the voltage class of common low-voltage industrial inverters. Protection against oils, coolants, and repeated abrasion comes from a PUR outer jacket that remains pliable during continuous-flex operation. The minimum dynamic bending radius is 7.5 × D, while fixed installation permits a minimum static bending radius of 5 × D. Following these bending limits helps prevent conductor fatigue and preserves dependable electrical performance throughout the cable’s service life.
The cable has a rated service life of 5,000,000 bending cycles, supporting use in rapid-motion axes that move repeatedly during production. The conductor insulation withstands temperatures up to +90 °C. The complete cable operates within a temperature range of -30 °C to +80 °C, allowing cold starts in unheated plants while also accommodating elevated operating temperatures. The jacket is orange (RAL 2003), providing high visibility when the cable is routed through machinery or organized inside a cable carrier. Its flexible jacket and high cycle rating make it suitable for drag-chain routes exposed to repetitive motion, industrial fluids, and abrasion.
