Product Description:
The RKL4578 is a factory-terminated power lead manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It links servo drives to motor terminals in automated machinery, delivering three-phase energy and auxiliary signals while remaining flexible enough for continuous motion axes and drag-chain routing.
The copper cores devoted to motor phases feature a cross-section of 16.0 mm², permitting a continuous load of 71.3 A at 40 °C without derating. When laid in a stationary run, the cable may be bent down to a radius of 5 × D; this compact curvature is aided by a PUR jacket that resists abrasion and oils. An overall diameter of 25.5 mm balances ampacity with routing convenience, and the braid plus foil construction forms a Total Shield that limits emitted electromagnetic noise in dense control cabinets. Two twisted-pair control cores, each 1.5 mm², share the sheath for brake release or thermal sensing.
Dynamic service life is extended to 5,000,000 bending cycles when the cable moves in a drag chain at the recommended flexible radius of 7.5 × D. Machine builders gain rapid enclosure sealing thanks to the pre-crimped metal plug that mates with a thread size of M40 × 1.5. During overloads, the conductor strands may reach up to 80 C yet remain within the thermal limit of the insulation system, and the vivid Orange (RAL 2003) outer jacket ensures clear identification among signal wiring. PUR compound insulation, along with the affirmative drag-chain rating, reduces downtime caused by cable fatigue in high-stroke gantries or palletizers.
Wake Industrial offers a 1-year warranty on each RKL4578 cable. Same-day shipping is available for urgent maintenance orders. Quotations issued for this part remain valid for 30 days to aid budgeting.
