RKL4606 by Bosch Rexroth Indramat

The RKL4606 is a motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It is supplied as a finished assembly that links servo drives to field-mounted motors, carrying three-phase power while maintaining the bend endurance required inside moving machine axes and cable chains. In automated production cells, the cable's predefined length, connectors, and jacket geometry reduce wiring work and provide a predictable electrical connection between the controller and actuator.

The cable has a Basic construction class, meaning the jacket and conductor insulation use the standard material mix for general-purpose motion tasks. It is delivered as a Ready-Made harness, so no additional crimping or overmolding is needed at installation. Mechanical service life is rated for 5,000,000 bending cycles, allowing repeated flexing in dynamic drag-chain applications before conductor fatigue becomes critical. During motion, the jacket must not be forced tighter than a dynamic radius of 7.5 x D, where D is the cable's outer diameter, while stationary routing may use a reduced static radius of 5 x D. Following these bend radii helps prevent microcracking of copper strands and preserves shield integrity against electromagnetic leakage.

Power conductors are terminated on the motor side with pre-installed Ferrules, and the drive-side interface uses a keyed RLS0721 Plug Connector. This pairing helps prevent pinout mismatches and keeps the assembly ready for direct connection. The product is a power cable variant within the RKL family, so it transmits motor phase current and protective earth without embedded feedback cores. Operating temperatures range from -30 °C for cold-start conditions in unheated plants up to 80 °C for continuous use near heat sources, so dielectric strength and jacket flexibility remain suitable across typical industrial temperature changes.
