Product Description:
The RKL4639 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Intended for dynamic servo axes, the cable delivers drive output to a motor while carrying auxiliary control cores in the same jacket, reducing routing complexity inside energy-chain systems.
Mechanically, the cable endures up to 5 million bending cycles, a rating that supports continuous motion in drag chains without conductor fatigue. Electrically, its line-to-line capacitance is specified at 1.0 nF/m; low capacitance limits reactive currents and helps the drive hold a stable switching pattern. Each copper core presents a resistance of 1.91 Ω/km at 20 °C, ensuring predictable voltage drop calculations over extended runs. Two 1.0 mm² and two 1.5 mm² control pairs, identified as 2x1.0 + 2x1.5 mm², are integrated for brake or temperature signals. All elements reside inside an overall diameter of 22.2 mm, allowing routing through standard chain separators and cable glands.
The outer sheath is colored Orange (RAL 2003) for quick identification of power wiring and manufactured from abrasion-resistant PUR to resist oils and coolants. When installed permanently, the cable operates between -30 to +40 °C; during dynamic movement the flexible range narrows to -20 to +40 °C, aligning with the mechanical limits of the sheath compound. Identical limits apply to storage, so warehouse conditions can match on-machine environments without additional controls.
