Product Description:

The RKL0061 is a motor power cable from Bosch Rexroth Indramat’s RKL Motor Power Cables series, supplied to link IndraDrive or Diax servo amplifiers with matched motors in automated machinery. Its multi-core layout carries three-phase power, protective earth, control, and auxiliary signals in a single sheath, providing a compact wiring route inside drag chains and fixed-installation conduits.

An overall diameter of 18.5 mm balances current capacity with routing space, while the composite core build of [4x6.0 mm²+(2x1.0)StC+(2x1.5)StC] separates power, control, and brake circuits to minimise crosstalk. Copper resistance is limited to 3.30 Ohm/km at 20 °C, so voltage drop stays low on long runs. The cable shows a discharge capacitance of 0.8 nF/m, reducing common-mode noise that can trip drive monitoring. A tough PUR (adhesion-free, matte) outer jacket resists oil and coolant and allows easy bundle separation during service.

For cabinet wiring the minimum static bend is 5 x D, and in continuously moving energy chains it tolerates a dynamic radius of 7.5 x D, supporting tens of millions of cycles without conductor fatigue. The core insulation endures up to +90 °C when clamped, yet remains flexible down to +80 °C in motion, ensuring thermal stability near servo motors. Three power conductors plus PE each carry 6 mm², while two 1.0 mm² control conductors and two 1.5 mm² auxiliary conductors provide brake and sensor supply, so a separate feedback cable is not burdened by auxiliary loads.
