Product Description:
The RKL4440 is a flexible motor-power cable from Bosch Rexroth Indramat RKL Motor Power Cables series, specified for routing drive output to servo motors in dynamic automation axes. Its construction, accessories, and tested life make it a ready-to-install link between IndraDrive amplifiers and terminal boxes where mechanical motion and electrical noise must be controlled simultaneously.
The cable endures up to 5,000,000 bending cycles, so energy-chain applications can operate through years of acceleration without conductor fatigue. A robust outer diameter of 25.5 mm provides space for low-resistance phase conductors with a cross-section of 16.0 mm², limiting voltage drop and heating at continuous motor currents. Mechanical protection is delivered by a PUR jacket that resists cutting oils, welding sparks, and abrasion while maintaining flexibility at low temperatures.
Thermal performance is capped by a maximum conductor temperature of 80 °C, allowing the assembly to run beside warm motors and drives without insulation degradation. Signal integrity is maintained by a Total Shield wrapped around the cores, reducing common-mode emissions into neighboring feedback lines. At the motor end, an EMC fitting thread of M40 × 1.5 bonds the shield 360 degrees to the housing, while the drive-side bulk cable designation INK0606 confirms compatibility with prefabricated RKL connectors. The orange jacket (RAL 2003) meets machinery-safety color codes, and the assembly mates to terminal-box size 4 without additional ferrules.
