Product Description:
The RKL0049 cable is supplied by Bosch Rexroth Indramat as a member of the RKL Motor Power Cables series. It links drive controllers to synchronous motors in industrial automation lines, carrying phase power, auxiliary feedback, and protective earth across continuously moving machine axes. Use in cable tracks demands mechanical resilience, and this model is built to maintain electrical performance while executing millions of reciprocal strokes inside packaging, printing, or assembly equipment. The plug-and-play terminations on each end further shorten installation time in control cabinets and motor junction boxes.
Primary current is transmitted through 4x6.0 mm² power conductors, a cross-section selected to keep voltage drop low on axes with moderate continuous current. Control and thermal sensors can share the auxiliary bundle of 2x1.0 mm² + 2x1.5 mm² cores, segregated from the motor phases to avoid crosstalk. The overall circular jacket measures 18.5 mm in diameter, giving room for the conductor set and PUR insulation while still fitting standard drag-chain compartments. Resistivity of 3.30 Ω/km at 20 °C defines losses over long runs, and the cable is supplied in Bulk Cable type INK0604 for cut-to-length production. During motion, a dynamic bending radius of 7.5xD supports chain articulation, and testing confirms a service life of 5,000,000 bending cycles without conductor breakage.
Stationary sections may be laid with a minimum loop of 5xD, reducing stress at cabinet entries. The outer sheath is formed from PUR, which resists mineral oil and coolant splash while preserving flexibility. Thermal ratings allow continuous operation up to 90°C on fixed portions and 80 °C on moving sections, ensuring conductor insulation does not embrittle during enclosure heating. An over-moulded RLS0749/K06 connector mates with the controller, while the motor end terminates in an RLS1201/C06 plug for quick exchange. Together these features create a matched interface that minimizes wiring time and maintains signal segregation through the power and auxiliary paths.
