Product Description:
The RKL4624 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is designed to supply three-phase power and auxiliary control lines between drives and servomotors in automated machinery. It also maintains electromagnetic compatibility in moving cable tracks and fixed cabinet runs.
The cable carries motor current through a power conductor cross-section of 25.0 mm², allowing moderate-to-high load transmission without excessive voltage drop. Its power cores are rated for up to 300/500 V under VDE rules, and the separate control pair operates at 300/300 V, so drive encoder or brake circuits stay within their own insulation class. Copper resistance is limited to 0.78 Ω/km at 20 °C, which reduces I²R heating over long runs, and a line-to-shield discharge capacity of 1.1 nF/m provides predictable drive output filtering. A total shield built from tinned-copper braid and foil encloses all conductors to block inverter-generated radio-frequency noise.
The cable uses a flex-optimized PUR jacket; the PUR (Adhesion-Free, Matte) outer sheath resists coolant, oil, and weld splatter while gliding smoothly in energy chains. Continuous motion applications are supported for up to 5,000,000 bending cycles, provided the dynamic bend radius is held at 7.5 × D; static routing may tighten to 5 × D without damaging the cores. The cable endures conductor temperatures up to 90 °C when fixed and up to 80 °C during motion, enabling operation in motor housings and warm control cabinets. Two twisted signal pairs, listed as 2×(2×1.5 mm²) StC, travel alongside the power cores for brake release or thermal sensing, and the cable is approved for drag-chain use with fillers and stranding that keep the bundle stable during high-speed reciprocating travel.
