Product Description:
The RKL4727 is a flexible motor power cable developed by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It forms the electrical backbone between an IndraDrive controller and a servo motor, carrying three-phase power and protective earth through factory-terminated connectors. The cable is built for continuous motion in drag-chain environments, helping automation systems maintain stable current delivery under fast, repetitive axis movement.
The mechanical life of the cable reaches 5,000,000 bending cycles, indicating suitability for high-duty cable carriers that open and close thousands of times per shift. Three power cores with a cross-section of 25.0 mm² minimise voltage drop on long runs and allow high peak currents during motor acceleration. Dynamic routing is assisted by a recommended minimum loop of 7.5xD, so the conductor bundle can bend without copper fatigue. A tough PUR outer jacket shields the cores against coolants and oil mist while resisting abrasion inside metal guide channels.
For static sections, the installation bend can be reduced to 5xD, simplifying cabinet entry without adding strain to the conductors. Internal control pairs are sized at 1.5 mm² to carry brake or sensor supply lines alongside mains phases. The jacket is coloured RAL 2003 orange for quick identification of hazardous voltage runs, and the phase-linked earth wire is coded GNYE to meet EU protective-conductor conventions. These features combine to keep electrical parameters stable over the full dynamic range outlined in the previous paragraph.
Wake Industrial stocks this cable assembly, can arrange same-day shipping when required, and keeps quotations valid for 30 days so maintenance teams can schedule replacements with minimal paperwork.
