Product Description:
The RKL0050 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It serves as a flexible link between IndraDrive power stages and synchronous motors, carrying three-phase supply lines and low-level control cores in automated machinery that demands continuous motion. Because it integrates both power and auxiliary signals in a single shielded bundle, it lowers cabinet wiring time and reduces potential failure points on gantry axes, pick-and-place modules, palletizing robots, and other multi-axis assemblies.
To withstand repetitive movement the cable is rated for 5,000,000 bending cycles, and it can flex around a dynamic radius of 7.5xD while the static installation requirement is 5xD. The overall diameter of 12.2 mm keeps routing compact, and the jacket uses PUR to resist oil, coolant, and abrasion. Power conductors with a cross-section of 1.5 mm² are complemented by separate control pairs sized at 0.75 mm², enabling combined energy and feedback transmission. A braided copper screen surrounds all cores, providing low-impedance grounding for EMC compliance during high-frequency inverter switching. Bulk cable designation INK0650 is applied when assemblies are supplied in custom lengths to match unique axis travel.
Electrical performance is defined by a conductor resistance of 13.3 Ohm/km at 20 °C, supporting stable voltage over extended runs. The molded motor-side interface is the RLS1201/C02 connector, while the drive-side termination uses RLS0749/K02 to mate with cabinet modules and accept standard strain-relief clamps. For quick field identification the outer sheath is colored RAL 2003 (orange), and a control-core area of 0.75 mm² simplifies encoder or brake circuits that share the same drag chain. These parameters, together with the specified static bending radius of 5xD, align the cable with mobile axis packages that require high cycle life without derating during continuous shift operation.
