Product Description:
The RKL4759 is a flexible motor power and control cable produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. Designed for servo-axes that move in energy chains or robotic joints, the assembly conveys mains power and auxiliary signals from a drive controller to the motor. It is supplied as a finished lead that uses the RLK1301 motor-side interface and the RLS1202/C04 cabinet plug, allowing direct connection without onsite terminations. The underlying bulk cable type is INK0602, ensuring mechanical compatibility with other products within the same cable family.
Four copper power cores of 2.5 mm² each handle the main phase current, and with 4 power conductors available the cable maintains symmetrical loading for three-phase drives that also need a protective earth. For motor winding insulation, the assembly supports a maximum system voltage of 300/500 V, while line losses are limited by a conductor resistance of 7.98 Ohm/km at 20 °C. During dynamic motion the cable may bend to a radius of 7.5 x D, a value chosen to avoid conductor strand fatigue when the product is routed inside high-cycle drag chains.
Control functions are handled by two shielded pairs, each built with conductors of 1.0 mm², and these auxiliary cores are rated for 300/300 V instrumentation circuits that run alongside the power phases without crosstalk. The cable carries a polyurethane jacket in Orange (RAL 2003) for high abrasion resistance and easy identification, and the PUR sheath resists cutting oils common near machine tools. For static installation the minimum bend limit improves to 5 x D, while tests confirm service life beyond 5 million cycles when installed in a drag chain. Continuous movement is possible because the design is approved for drag-chain use and the matched RLK1301 and RLS1202/C04 connectors prevent torsional stress at the terminations.
