Product Description:
The RKL4530 motor power cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is engineered for routing inside energy-guiding chains, delivering drive power and feedback signals between controllers and servo or spindle motors in automated lines. By combining high-current conductors with shielded auxiliary pairs, the cable supports rapid axis movement and maintains electromagnetic compatibility during continuous industrial operation.
The mechanical design is rated for 5,000,000 bending cycles, illustrating suitability for constant drag-chain motion. Electrical losses are limited by a conductor resistance of 0.78 Ω/km, keeping voltage drop low over extended runs. Two shielded control pairs identified as 2 x (2 x 1.5 mm²) carry encoder or brake signals separate from the three-phase supply. A robust outer sheath made of PUR resists oil, coolant and abrasion, while its high-visibility RAL 2003 orange color simplifies cable tracing in dense cabinets. Installation rules specify a minimum fixed bend radius of 149 mm and a dynamic radius of 223.5 mm, preventing conductor fatigue. Overall diameter measures 29.8 mm, a dimension that guides routing channels and gland selection, and four 25 mm² power cores provide the current-carrying capability required by medium-frame servo motors.
These characteristics allow the cable to retain electrical integrity under prolonged mechanical stress and to integrate easily with other Rexroth components. The pre-assembled power connector INS0382/C25 forms a sealed, vibration-safe termination that expedites field replacement and reduces wiring errors. Separation between the power bundle and the shielded pairs limits crosstalk, helping drives read feedback signals accurately during rapid acceleration. Observing the defined bend radii and using the abrasion-resistant jacket extends service life, enabling predictable maintenance intervals for gantry axes, tool changers, and packaging machines that rely on constant flex cables.
