Product Description:
The RKL4351 is a motor power cable developed by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It delivers three-phase power and auxiliary control signals between Indramat drives and servo motors, supporting dependable energy transfer in drag-chain guided axes and other motion platforms where repeated flexing is unavoidable.
The mechanical design centers on endurance and flexibility. A flex life of 5,000,000 bending cycles allows the cable to operate for prolonged periods inside high-duty cable carriers. Overall outer dimensions are shaped by a 17.0 mm cable diameter that balances current capacity with routing convenience in densely packed tracks. Dynamic movements are accommodated by a minimum bend radius of 7.5 × D when the cable is in motion, limiting copper strand fatigue during continuous acceleration and reversal. A tough PUR jacket resists abrasion, coolants, and industrial oils while maintaining flexibility across common plant temperature ranges.
Electrical and interface features match standard Rexroth servo packages. The power cores support up to 600 VAC, providing headroom for synchronous motor systems fed from modern inverter outputs. Each phase is formed by a 4 × 4.0 mm² conductor set, giving low voltage drop over typical machine lengths. At the cabinet end, wiring terminates in the RLS0721/K04 drive connector set, while the motor side is equipped with a keyed RLS1207 mating plug for fast installation without field crimping. These factory-fitted connectors maintain shielding continuity and ensure reliable strain relief during rapid axis motion.
Wake Industrial holds this cable in stock, offers same-day shipping options for urgent orders, and supplies a 1-year warranty with every purchase. Quotations issued for the RKL4351 remain valid for 30 days to simplify budget approval cycles.
