Product Description:
The RKL4338 cable is a factory-terminated power lead manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It links drive controllers to servo motors and carries main phase current as well as protective earth, eliminating onsite crimping or soldering. Because it is supplied as a ready-made assembly, installation time is shortened and wiring errors are minimized in automated machinery that features continuously moving axes.
This power cable is specified for 5,000,000 flex cycles, so it withstands repeated motion in drag-chain or robot-arm routing. Four conductors with a cross-section of 4x6.0 mm² handle motor currents while keeping voltage drop within drive limits. An outer diameter of 18.5 mm balances ampacity with compact routing space inside energy tracks. During operation, the cable may be bent dynamically to a radius of 7.5xD, reducing stress on terminations during high-speed travel. Its sheath is formed from PUR, a material chosen for abrasion resistance, coolant compatibility, and low halogen content, making the assembly suitable for machining centers and automated assembly lines.
Total electromagnetic interference is curtailed by a Total Shield that encloses the core bundle, improving motor feedback signal integrity in parallel cable runs. Factory-molded plugs—RLS1301 on the drive side and RLS1302 at the motor—provide keyed, vibration-resistant latching without additional adapters. The construction tolerates ambient temperatures from -30 °C up to 80 °C, allowing cabinet or robot-arm mounting near warm servo stages. A static bend radius of 5xD supports fixed routing points, and the orange jacket in RAL 2003 gives rapid visual identification of energized motor lines within multi-cable harnesses.
