Product Description:

The RKL4413 belongs to the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. It is a shielded motor power cable intended to connect Indramat servo drives to synchronous or asynchronous motors in automated machinery. The cable supports stable power transmission while limiting electromagnetic interference, making it suitable for cabinet-to-motor runs on moving axes and in stationary installations.

For cabinet routing, the minimum fixed bending radius is 5 × D, while dynamic cable chains require a larger radius of 7.5 × D; these limits help maintain conductor integrity during repeated motion. The power cores are rated for up to 300/500 V, and each power core has a cross-sectional area of 6.0 mm², matching the current demands of typical Rexroth motors up to approximately 20 A. Internal wiring follows a composite layout of 4 × 6.0 mm² + 2 × 1.0 mm² StC + 2 × 1.5 mm² StC. This arrangement places two smaller shielded control pairs alongside the four larger power conductors, allowing brake or temperature signals to travel without a separate cable. Bulk cable code INK0604 identifies the extrusion profile and screening geometry used throughout the series.

The copper conductors have a loop resistance of 3.30 Ω/km, which keeps voltage drop within drive tolerances for cable lengths typically encountered on gantry systems. The insulation system has a mutual capacitance of 0.8 nF/m, so reactive current remains low even when the cable run approaches 50 m. A wear-resistant outer jacket made from PUR resists oils and cutting fluids, while its matte surface helps prevent adhesion inside drag chains. Visual identification in crowded cable trays is simplified by the jacket’s high-visibility RAL 2003 orange color. The shielding helps contain electrical noise generated by motor switching and reduces interference with nearby signal wiring.
