RKL4767 by Bosch Rexroth Indramat

The RKL4767 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It provides the fixed and dynamic power connection between a drive controller and its motor, pairing with the dedicated RLK1401 connector on the motor side and the RLS1302/C10 plug toward the drive cabinet. The cable's total shield and PUR jacket support electrically quiet delivery of three-phase energy in industrial automation lines that require continuous motion inside cable carriers. It is intended for installations that combine stationary cabinet wiring with repeated machine movement.

The bulk conductor set corresponds to type INK0605, which identifies the internal stranding pattern and insulation layout used by the manufacturer. Electrical losses are limited by a conductor resistance of 1.91 ?/km measured at 20 °C, allowing predictable voltage drop calculations over long runs. Visibility in crowded routing trays is improved by the jacket color RAL 2003 (orange). That outer sheath is molded from PUR, a material selected for abrasion resistance, oil tolerance, and flexibility over an extended service life. Continuous conductor temperatures may reach 80 °C without degrading dielectric strength, enabling installation in cabinets that operate near typical drive heat sink exhaust levels.

The minimum fixed bend radius is 5 × D, and the flexible bend radius is 7.5 × D, where D is the overall diameter. With an outer diameter of 22.2 mm, these ratios simplify routing guidelines for energy chains and swing arms. The copper power cores provide a cross-sectional area of 10.0 mm², delivering ample ampacity for medium-frame servo motors while keeping cable bundle size manageable. The design is suited for drag-chain motion cycles and maintains shielding continuity across both connectors so that conducted emissions remain within drive system limits.
