Product Description:
The RKL4444 cable is a motor power lead manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It supplies three-phase drive current and auxiliary signals between Indramat servo drives and synchronous motors, supporting automated machinery that relies on timed torque delivery and low-resistance conductors. The cable is specified for dynamic routing in cable chains and on moving axes, making it integral to flexible robotic and gantry installations.
At core level, the bulk cable type is INK0605, indicating insulation and conductor geometry compatible with RKL connector assemblies. Its composite build of [4x10.0 + 2x(2x1.0)StC + 2x(2x1.5)StC]C separates power, brake, and sensor pairs to reduce crosstalk during high-frequency switching. Overall diameter measures 22.2 mm, so cabinet glands and drag-chain guides must accept a 23 mm bore. Each power core provides a cross-section of 10.0 mm², keeping voltage drop low at typical servo currents. The outer jacket is made of PUR, chosen for abrasion resistance and coolant immunity, and it is molded in the visibility-standard orange tone designated RAL 2003 for quick identification in multi-cable bundles.
Thermal limits are defined so continuous stationary wiring can reach +90 C at the copper while flexing applications are limited to +80 C; these ratings assist drive engineers in predicting conductor loss and derating factors. During motion, ambient operation can continue down to -20 C without jacket embrittlement. For repeated bending, the minimum dynamic loop is 7.5 × D, which equates to roughly 167 mm for this cable, while static harnesses may be clamped at five-diameter curves. These parameters allow routing inside energy chains or rotary trays without exceeding mechanical strain.
