Product Description:
The RKL4732 is a motor power cable produced by Bosch Rexroth Indramat and grouped within the RKL Motor Power Cables series. It links an IndraDrive controller to a synchronous or asynchronous motor so that three-phase power, protective earth, and control cores can be routed in a single shielded assembly for industrial automation axes that demand coordinated motion and low electrical noise.
This cable is supplied as bulk type INK0604, a designation that identifies its insulation and shield structure. Inside the sheath the core layout follows the pattern [4x6.0 mm²+(2x1.0 mm²)StC+(2x1.5 mm²)StC]C; four 6 mm² phase conductors carry the drive current, while two signal pairs with overall copper braids support temperature or brake circuits. Its mutual capacitance is rated at 0.8 nF/m, limiting charging currents on long runs, and the loop resistance is 3.30 Ohm/km at 20 °C, a value that guides permissible length before voltage drop becomes critical. The black outer jacket brings the overall diameter to 18.5 mm, and both the phase and PE conductors share a 6 mm² cross-section suited for circuits up to 600 V AC.
Mechanical service life is enhanced by a PUR jacket, denoted by the flexible and abrasion-resistant material tag PUR. When the cable is installed in energy chains the dynamic bend radius must not fall below 7.5xD, while stationary routing allows a 5xD static radius. Factory-terminated plugs simplify connection; the drive end is fitted with a RLS0723 (K06) angled hybrid connector, and the motor end uses the keyed RLK1401 coupling to match standard Rexroth motor housings. These connectors keep the shield intact, reduce assembly time, and preserve EMC compliance during high-frequency drive switching.
