Product Description:
The RKL4575 is a dedicated motor power cable created by Bosch Rexroth Indramat for use in the RKL Motor Power Cables series. Designed for integration into servo-drive loops, the cable transmits mains power and encoder auxiliary lines between the cabinet inverter and moving motor assemblies. Its purpose in industrial automation is to maintain reliable electrical delivery while withstanding continuous movement inside cable tracks, allowing gantries, robots, and linear stages to operate without unplanned downtime during daily production.
Bending endurance of 5 million cycles allows the cable to survive repetitive motion in high-duty drag chains. A robust outer diameter of 25.5 mm gives adequate wall thickness for dielectric strength and mechanical protection. The copper conductors exhibit a loop resistance of 1.21 Ω/km, so voltage drop remains low over typical machine lengths. Its construction is rated as Drag Chain Suitable, confirming the bundle resists torsion and abrasion during accelerated travel. Finally, the insulation system supports an operating line potential of 600 VAC, matching most medium-power servo drives.
The signal and power layout follows the 4x16 + 2x(2x1.5) StC scheme, separating four 16 mm² phase cores from paired 1.5 mm² control pairs to reduce crosstalk. A distributed capacitance of 1.2 nF/m limits reactive current in high-frequency switching environments, helping the drive maintain a clean sine-wave form. The orange outer sheath is made of resilient PUR, providing resistance to oils and coolants while meeting machine-tool safety visibility requirements. When routed dynamically, the cable may bend to a radius of 7.5×D; fixed installations can tighten to 5×D. The specified bulk type INK0606 aligns with Bosch Rexroth assembly drawings.
