Product Description:
The RKL4603 is a pre-assembled motor power cable produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. Designed for dynamic cable-track applications, it supplies three-phase energy and auxiliary signals between drive controllers and servo motors in automated equipment. By integrating power and control cores within a tough industrial jacket, the cable simplifies wiring and maintains electromagnetic compatibility on packaging machines, pick-and-place axes, and other continuous-motion assemblies.
The cable withstands a fixed ambient range of -30 to +40 °C; during motion the allowable window is -20 to +40 °C. A matte, adhesion-free PUR jacket in RAL 2003 orange resists oils and aids visibility. Flexibility is maintained with a dynamic bend radius of 7.5 × D and a static limit of 5 × D. These parameters minimize conductor fatigue and keep electrical performance stable.
The service life is validated for 5,000,000 bending cycles in high-speed chain tracks, a figure derived from the underlying INK0602 bulk cable that forms the core of the assembly. Four power cores, each with a cross-section of 2.5 mm², deliver the motor phase current, while four screened control wires of 1.0 mm² relay brake or temperature signals. At the drive side, an RLS0721/K03 molded connector locks to IndraDrive power modules; the motor side is factory-crimped with ferrules to speed installation and guarantee low contact resistance. This conductor layout balances current capability with manageable outer diameter so the chain can operate smoothly under the specified mechanical envelope.
Orders can be routed through Wake Industrial, where same-day shipping is available for time-critical maintenance. International shipping options let facilities outside North America receive genuine Rexroth cabling without extended delays. For budgeting purposes, quotations issued for this model remain valid for 30 days.
