RKL4469 by Bosch Rexroth Indramat

The RKL4469 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series and serves as the primary power link between drive amplifiers and synchronous motors in automated equipment. It combines power cores and auxiliary control pairs in a single jacket, so routing remains straightforward in moving or stationary sections of a machine. By supporting both fixed and dynamic layouts, the cable suits gantries, pick-and-place axes, and other motion platforms that alternate between continuous travel and standstill.

The cable maintains a minimum fixed bending radius of 5 × D and requires a larger radius of 7.5 × D when used in drag chains, helping prevent conductor fatigue during millions of cycles. Its core arrangement of 4x16.0 mm² + 2x(2x1.5 mm²)StC separates three phase leads, a protective conductor, and two screened signal pairs to reduce crosstalk. The overall diameter of 25.5 mm helps size carrier trays and gland fittings without excess slack. A wear-resistant PUR outer sheath resists oil and coolant, supporting long service life in machining centers and packaging lines where lubricants or washdown conditions are present.

The cable includes 2 dedicated signal pairs that can support temperature sensors or holding-brake supply lines without requiring an additional harness. The high-visibility RAL 2003 (Orange) jacket helps distinguish power circuits from data cables inside electrical panels and machine runs. In fixed installation, the wire insulation tolerates continuous conductor temperatures up to 90 °C, while flexing operation is limited to 80 °C so heat rise from current load and ambient sources remains controlled. A power-wire resistance of 1.21 ?/km keeps voltage drop low over typical machine lengths, and the cable is suitable for repetitive motion in drag chain applications.
