Product Description:
The RKL4485 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for connecting servo motors to their drives, the product carries both power and auxiliary control signals between the controller cabinet and the motor housing in automated machinery. Its construction, interfaces, and thermal limits are intended to maintain stable current delivery and signal integrity in dynamic cable-chain applications common in industrial robots and material handling axes.
The electrical section consists of four stranded copper power cores with a cross-section of 2.5 mm²; they are rated for a continuous phase-to-phase potential of 300/500 V. A separate shielded quad of control leads handles encoder or brake feedback and maintains a discharge capacitance of 0.7 nF/m, a value that reduces reactive currents when long lengths are driven from fast-switching inverters. On the controller end, termination is pre-molded to a RLS0722/K03 plug, allowing direct engagement with Rexroth drive modules without field crimping. The identical power and control reference counts simplify sizing calculations when selecting circuit protection and contactors.
At the motor side a RLK0004 connector mates with the housing feed-through, preserving the cable’s sealing concept. Four signal conductors for temperature sensors or brake release are present, matching the 4 power conductors so that control and power share the same external sheath. Each auxiliary core uses a diameter of 1.0 mm², balancing flexibility with voltage drop limits. Thermal endurance reaches +90 °C when the run is fixed and +80 °C during continuous motion, which meets drag-chain requirements for accelerated cycles. The outer jacket is extruded from PUR in a highly visible Orange (RAL 2003) tone that resists abrasion, oil, and cutting fluids. Overall capacitance, interface coding, and mechanical shielding combine to limit electromagnetic coupling into neighboring cables.
