Product Description:
The RKL4646 is a motor-power cable manufactured by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It links a drive controller to a servo motor, transferring three-phase power and protective earth while tolerating repetitive motion inside drag chains that populate modern CNC machines and automated assembly lines.
This cable survives up to 5,000,000 flex cycles without conductor or jacket failure. A nominal outside diameter of 29.8 ± 1.0 mm balances current-carrying cross-section with compact routing in energy guides. Distributed capacitance is held to 1.1 nF/m, minimizing reactive loading on fast-switching inverters, and loop resistance is limited to 0.78 Ω/km at 20 °C to curb voltage drop on extended runs. For fixtures that remain stationary after installation, the copper bundle can operate continuously at a conductor temperature of +90 °C without derating.
A tough PUR outer sheath protects the cores and maintains a fixed bend radius of 5xD, whereas dynamic installations must respect a flexible radius of 7.5xD to avoid work-hardening. The jacket is colored Orange (RAL 2003) for quick visual identification of high-power circuits among signal wiring. Bulk cable type INK0607 is factory-terminated with an RLS0724/K25 controller plug and an RLK0007 motor connector, so no field crimping is required. Positive drag-chain suitability, together with PUR abrasion resistance and the specified radii, ensures service life in robotic axes where torsion and linear travel occur simultaneously.
