Product Description:
The RKL4407 motor power cable is manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It serves as the link between drive amplifiers and servo motors, carrying three-phase power, control voltage, and protective earth conductors so motion axes in industrial automation remain supplied under dynamic duty cycles.
The cable’s composite bundle contains 4 × 6.0 mm² power cores plus twin signal pairs, expressed as the 4x6.0 + 2x1.0 + 2x1.5 mm² conductor configuration. A PUR sheath rated to RAL 2003 (Orange) resists oils and weld spatter while its 18.5 mm outer diameter fits standard Rexroth connectors. Power lines support up to 300/500 V whereas the auxiliary pair is limited to 300/300 V, allowing mixed-voltage routing in one cable. For continuously moving machine sections the flexible section may bend down to 7.5 × D; below this radius mechanical fatigue will accelerate. When flexed, the assembly remains serviceable up to +40 °C, preventing insulation softening during typical enclosure temperatures.
Bulk cable type INK0604 designates the exact material stack and screen layout adopted by Rexroth. A low - resistance copper matrix of 3.30 Ω/km curtails voltage drop across long runs, and individual 6.0 mm² power wires handle peak load currents without overheating. The product is approved for drag-chain use, so repeated cycles exceed one million strokes provided the fixed bend radius of 5 × D is respected. Continuous conductor temperatures may reach +90 °C, while operation can start at −20 °C and the 6.0 mm² power cross-section maintains ampacity through that range. The vivid orange jacket and PUR compound simplify identification and ensure abrasion resistance in guided-way carriers.
Wake Industrial offers a 1-year warranty on each cable, can arrange same-day shipping for urgent orders, and keeps quotations valid for 30 days to assist maintenance planners.
