Product Description:
The RKL4483 is a flexible motor power cable from Bosch Rexroth Indramat within the RKL Motor Power Cables series. It carries three-phase drive power and auxiliary signals between an IndraDrive controller and the motor terminal box in automated machinery. Combining power conductors and low-voltage control pairs in one jacket simplifies routing inside energy chains while maintaining the signal integrity required for coordinated servo motion. This combined arrangement also reduces the number of separate cables that must pass through moving carriers and confined machine spaces.
The assembly uses four power conductors, each with a cross-sectional area of 6.0 mm², to carry three-phase power and protective ground. Under dynamic motion, the cable withstands 5,000,000 bending cycles, allowing installation in high-duty drag chains without premature fatigue. During continuous flexing, the jacket must not be forced below a bend radius of 7.5 × D, while fixed runs permit a minimum bend radius of 5 × D. Observing these bend limits preserves the conductor geometry and helps minimize electrical losses across long machine axes. The conductor arrangement supports the power demands of compatible servo motors while leaving dedicated paths available for auxiliary functions.
The cable operates within a temperature range of -30 °C to +80 °C, supporting startup in unheated facilities and operation under full electrical load. It is manufactured from the INK bulk cable family and carries the designation INK0604. Its outer material resists oils and welding sparks that may be present near automated assembly lines. Factory-crimped contacts inside the RLS0721/K06 controller plug mate directly with compatible IndraDrive output terminals. The opposite end is fitted with ring terminals that connect to the RLK0003 motor terminal box without requiring separate connector assembly. Two shielded sensor pairs run beside the power cores, with 1.0 mm² conductors assigned to pins 5 and 6 and 1.5 mm² conductors assigned to pins 7 and 8. These shielded pairs carry temperature or brake signals while limiting crosstalk from the adjacent phase conductors.
