RKL0040 by Bosch Rexroth Indramat

The RKL0040 power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is a ready-terminated conductor set that links an IndraDrive controller to a synchronous motor, supplying three-phase power and a protective earth in automated machinery. By matching the drive and motor interfaces, the assembly reduces wiring work and supports dynamic axis motion in packaging lines, pick-and-place units, and other industrial equipment. Its ready-terminated layout also helps maintain a continuous grounding path and a consistent connection between compatible drive and motor components. This format helps keep installation orderly on axes where cable movement is repeated through many operating cycles.

Phase conductors inside the cable use a cross-section of 6.0 mm², which helps limit resistive loss during continuous current flow. An auxiliary pair sized at 1.0 mm² carries brake power or temperature sensor signals, so a separate small control lead is often unnecessary. During flexing operation, the assembly withstands 5,000,000 bending cycles, making it suitable for energy-chain or robot dress-pack routing. The minimum bending radius during motion is 7.5xD, which helps prevent the copper strands from being overstressed. On the controller end, the molded connector RLS0723/K06 mates directly with compatible IndraDrive terminals and preserves shielding continuity.

For fixed installation, the cable may be bent to a radius of 5xD, which helps conserve space in cabinets and cable trays. The motor end uses the keyed circular plug RLK3101/K06, which supports correct alignment at the motor junction and helps avoid connection errors in tight mounting spaces. Bulk material code INK0604 identifies the cable build used for the flame-retardant sheath and fine-strand copper intended for repeated motion. The protective-earth conductor is color-coded GNYE, making the grounding lead easy to identify during routing and connection. It is a Basic model supplied as a ready-made power cable assembly for direct installation on compatible equipment.
