Product Description:
The RKL4496 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It carries phase and protective grounding conductors from drive amplifiers to servomotors in industrial automation systems and is designed for continuously moving drag-chain installations on gantries, robots, and transfer lines. The cable combines fine-stranded copper cores with an abrasion-resistant sheath so that regulated power reaches the motor with limited voltage drop and without premature insulation wear.
The cable uses INK0605 bulk cable, which establishes the conductor geometry and insulation arrangement. Its dynamic service life reaches 5,000,000 bending cycles, allowing repeated travel in high-duty energy chains. An external diameter of 22.2 mm keeps the bundle compact while accommodating four 10.0 mm² power cores for medium-frame motors. The sheath consists of orange RAL 2003 PUR, a halogen-free material that resists oil, abrasion, and weld spatter. Electrical losses are limited by a conductor resistance of 1.91 Ω/km at 20 °C, helping reduce voltage drop over long cable runs. Phase identification follows the 1, 2, 3, and GNYE color code for clear conductor assignment during installation. The cable is approved for drag-chain use, and its fine-stranded conductors withstand the repeated bending associated with moving machine axes.
Thermal limits permit continuous service at up to +90 °C in fixed installations and up to +80 °C during continuous flexing, covering both stationary and moving cable routes. Fixed routing requires a minimum bend radius of 5 × D, whereas moving sections require a minimum bend radius of 7.5 × D to reduce conductor fatigue. The drive end terminates with an RLS0721/K10 controller connector, while the motor end uses an RLK0006 plug to provide secure connections at both interfaces.
