Product Description:

The RKL4612 power lead is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is a dedicated motor-to-drive connection that carries three-phase power and ground between an Indramat inverter and its companion rotary or linear servo motor. The cable is intended for automated handling, packaging, and machining cells where stable power transfer is required during repeated machine motion. Its assembled format avoids separate conductor preparation at the connection points and supports consistent installation on servo-driven equipment.

This cable is supplied as a ready-made assembly, so it arrives cut to length and jacketed for direct installation. It is rated for 5,000,000 bending cycles in cable-track layouts, indicating suitability for continuously moving axes such as gantries or robotic wrists. Dynamic routing is supported down to a bend radius of 7.5 x D, while fixed installations can follow a tighter 5 x D radius; here, D refers to the outer diameter of the cable. Although it is described as a power cable, the PVC sheath also contains a tinned drain wire that bonds to the ground conductor to control common-mode noise.

The copper conductors feature a cross-section of 25.0 mm², offering low resistive losses on long runs and supporting high motor current peaks during acceleration. At the drive end, a keyed RLS0723 connector provides direct mating to Rexroth power modules, while the motor end is finished with crimped ferrules that fit screw or spring terminals in standard motor junction boxes. Continuous service is maintained from a minimum ambient of -30 °C up to a maximum of 80 °C. The same limits apply during storage, so the cable can be kept in unconditioned warehouses without material damage. This arrangement supports use on long cable runs where voltage drop and flex life both matter.
