Product Description:

The RKL0102 is a power transmission cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is supplied as a pre-assembled line intended to convey three-phase drive power from inverter outputs to synchronous or asynchronous motors in automated machinery. By arriving pre-terminated, the assembly reduces installation time and helps maintain consistent electrical performance on dynamic axes that experience continuous motion.

As a moving-chain component, the cable is rated for 5,000,000 flex cycles, indicating the number of reciprocating bends it can withstand before conductor fatigue becomes critical. It tolerates combined bending and torsion of ±180°/30 cm, so the assembly can twist half a turn over a 300 mm span without insulation damage. Delivered as a ready-made unit, it does not require on-site crimping before installation. During operation, motion loops must respect a dynamic bend radius of 7.5 x D. When the machine is idle, the static radius can be tightened to 5 x D without exceeding allowable strain on the copper cores. The designation power cable indicates that the conductors are intended for motor current rather than encoder or feedback signals.

The cable uses a molded motor-side plug coded RLS1108 and a drive-side plug coded RLS0746, enabling direct connection to compatible Rexroth drives and motors without adapter hardware. Thermal endurance in service spans from -30 °C at cold startup to 80 °C during operation, so the installation environment must remain within that range. The same temperature range applies during storage, which helps preserve jacket flexibility before the cable is placed into service. Because the assembly carries only power conductors, it is intended for motor power runs rather than mixed-signal routing. Its bending and temperature capabilities suit high-cycle linear slides, pick-and-place arms, and gantry axes that operate under repetitive movement.
