Product Description:
The RKL4336 cable is a factory-terminated motor power lead produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is intended for routing three-phase energy and protective earth to servo motors while also carrying four auxiliary control cores, enabling coordinated motion in automated machinery that demands high flexing endurance.
The power cores are dimensioned as 3 × 2.5 mm² plus a matching PE conductor and are rated for 600 V AC. When installed immobile, the cable can be bent to a minimum arc of 5xD, whereas dynamic energy-chain runs require a larger radius of 7.5xD. An outside diameter of 14.8 mm allows compact routing through drag-chain separators, and the construction survives up to 5,000,000 flex cycles under prescribed test conditions. Terminations are supplied with RLS1301/C03 on the drive side and RLS1302/C03 on the motor side, eliminating field assembly. Power conductors are paired with the INK0602 bulk core design to maintain identical impedance along the full length.
The electrical path resistance of the copper phase set is 7.98 Ω/km, while line-to-shield capacitance measures 0.7 nF/m; together these values define voltage drop and common-mode current in long-axis installations. Four signal leads, each realised as 4x1.0 mm², permit temperature sensors or brake control to share the same harness. A robust outer sheath made of PUR provides abrasion and coolant resistance and remains flexible from −20 °C to +40 °C in mobile layouts; fixed routing extends the lower limit to −30 °C. The specification also lists a bending radius class of 5xD for fixed mounting, confirming compatibility with static cabinet wiring.
