Product Description:

The RKL4535 cable is part of the RKL Motor Power Cables series from Bosch Rexroth Indramat. It combines motor power conductors, a protective earth, and shielded control cores in one assembly, so a drive and a synchronous servo motor can be linked with a single cable run. This layout helps reduce routing complexity in automated production lines, including linear stages, gantry axes, and packaging equipment.

For stationary routing, the cable can be bent to 5 × D, while moving applications require a minimum bend radius of 7.5 × D. The cable has an outer diameter of 25.5 mm and a jacket in RAL 2003 (orange), which makes it easy to identify in cable ducts and machine frames. The jacket material is PUR, which helps resist abrasion and oil exposure in areas with repeated movement. The power conductors have a resistance of 1.21 Ω/km, which helps limit voltage drop over longer cable runs. Continuous conductor temperature can reach +90 °C in fixed routing, and the same temperature is permitted in flexing sections when the stated bend limits are observed.

At both the motor and cabinet ends, the cable uses an 11-pin bayonet lock connector for secure and vibration-resistant attachment. The control section uses conductors sized 4 × 1.5 mm², and these cores are intended for brake or sensor signals that are kept separate from the three-phase power set and protective earth. The control conductors carry a 600 VAC UL rating, supporting use in industrial machine wiring where auxiliary circuits need the same dependable insulation system as the main cable body. Line-to-shield capacitance is limited to 1.2 nF/m, which helps keep leakage current and EMC-related effects under control at typical PWM switching frequencies. This cable is suited for indoor machine tools and automated storage systems where combined power and control wiring is needed in one robust assembly.
