Product Description:
The RKL0042 is a motor power cable from Bosch Rexroth Indramat’s RKL Motor Power Cables series. Intended for dynamic servo-axis wiring, the assembly routes three-phase power and auxiliary signals between drive controllers and motors while tolerating continuous motion typical of gantry, robot, and transfer applications. Its construction balances mechanical flexibility with electrical capacity so that motion systems maintain consistent current delivery throughout long service lives.
The main conductors use a cross-section of 10.0 mm2, allowing low-loss transmission of high motor currents, while the separate auxiliary core is sized at 1.0 mm2 for brake or sensor supply lines. An overall diameter of 22.2 mm keeps routing manageable in drag chains without compromising insulation thickness. For fixed installation the cable may be bent to a radius of 5 × D; under continuous flex it should follow a wider arc of 7.5 × D to avoid conductor fatigue. Conductor resistance is specified at 1.91 Ω/km, a value that minimizes voltage drop over typical machine lengths while staying within IEC load limits.
Durability is defined by a lifecycle of 5000000 bending cycles, enabling multishift operation in high-duty plants. When clamped in place, it remains functional from -30 to +40 C; during mobile use the allowable temperature window is -20 to +40 C, covering most indoor production environments. The outer sheath is a rugged PUR compound colored orange (RAL 2003) for quick identification and high resistance to cutting fluids. Together these features ensure stable electrical characteristics, chemical resilience, and mechanical endurance in automated material-handling or machining cells.
