Product Description:

The RKL4620 is a motor power cable manufactured by Bosch Rexroth Indramat and supplied in the RKL Motor Power Cables series. It connects servo motors to their drives in automated machinery, carrying phase and protective earth conductors through cable tracks that experience constant motion. As a basic model, the assembly is intended for standard mechanical loads while still supporting the repeated flexing commonly found in pick-and-place axes, gantries, and packaging lines. Its construction suits installations where reliable power delivery must be maintained while the cable is routed through moving machine sections.

The cable is rated for 5,000,000 continuous bending cycles, so it can operate for long duty periods without conductor fatigue. During motion, it must follow a minimum dynamic bending radius of 7.5 × D, which limits strain on the copper and insulation layers. It is delivered as a ready-made harness with factory-terminated contacts, reducing wiring errors and shortening installation time. The motor-side interface uses the keyed INS0381 connector, which mates directly with compatible Rexroth servo housings and helps maintain correct orientation during connection. The cable continues to transmit power down to -30 °C, and its PVC jacket resists oil splash while the power cores support the current demand of medium-frame synchronous motors.

For stationary routing, the assembly observes a static bending radius of 5 × D, allowing compact cabinet entry without exceeding strain limits. It is classified as a power cable, so the conductor arrangement is intended for motor voltage and current transmission rather than signal handling. The drive-end plug is coded RLS0724, allowing quick replacement without crimp tooling. Thermal endurance reaches 80 °C during operation, and the same upper limit applies during long-term storage. The lower storage boundary matches the low-temperature operating limit noted above, which supports use in cold storage areas and unheated production spaces.
