RKL4711 by Bosch Rexroth Indramat

The RKL4711 motor power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. Designed for servo-drive installations, the cable links a power stage in the controller cabinet directly to a synchronous motor, carrying three-phase energy and auxiliary signals required by modern automation axes. Its construction targets assembly lines, gantry modules, and comparable equipment where compact wiring with matched connectors simplifies installation and maintains signal integrity under continuous motion. It integrates power and auxiliary lines in one sheath, reducing cabinet space and routing complexity.

The bulk conductor set uses the INK0604 cable family, providing an insulation system suited to factory environments. When the cable is installed in fixed routing, the minimum bend radius is 5 x D, while dynamic applications that require continuous flexing must observe 7.5 x D to protect the copper bundle. Three power cores with a cross section of 6.0 mm² support currents associated with drives up to 300 V. Four auxiliary cores, indicated by the control-conductor count of 4, carry enable, temperature, or brake signals without separate harnesses. Suitability for drag-chain trays lets the assembly follow high-speed axes without deformation, and the direct connection mode eliminates intermediate terminal blocks to reduce voltage drop.

On the control side, individual logic wires are sized at 1.5 mm², giving low-resistance paths for sensor circuits. The molded controller plug matches the RLS0723 (K06) interface, while the motor end is terminated with an RLK1201 coupling for direct mating at the motor. This connector pairing keeps shielding intact across the entire length and aligns pin assignments with compatible Bosch Rexroth Indramat drive families.
