Product Description:
The RKL4533 belongs to the RKL Motor Power Cables series produced by Bosch Rexroth Indramat. It is a flexible motor power lead designed to link drive controllers to servomotors in automated machinery, carrying mains power and auxiliary signals while maintaining electromagnetic compatibility on moving machine axes.
This cable carries phase conductors with a cross-section of 6.0 mm², giving sufficient ampacity for typical medium-power motors. Its overall layout is identified by the designation 4x6.0 + (2x1.0)StC + (2x1.5)StC, meaning four power cores plus two shielded 1.0 mm² pairs and two shielded 1.5 mm² pairs for brake or sensor lines. Despite the multi-core build, an outer diameter of 18.5 mm keeps routing straightforward in energy chains. The motor-end connector presents 3 + PE power contacts so the protective earth runs alongside the three phases, while the control insert offers 7 low-current pins for temperature, brake or encoder supply. A PUR jacket with a matte, adhesion-free surface resists cutting fluids and simplifies cleaning, and the green/yellow PE conductor remains immediately identifiable during installation.
Dynamic applications are supported by a service life of 5 million bending cycles when the motion radius stays above 7.5 x D. During continuous drag-chain duty the cores endure ambient conductor temperatures up to +90 °C in fixed routing and up to +80 °C when flexing, protecting insulation integrity during stop-start production. Auxiliary pairs provide 1.0 mm² and 1.5 mm² cross-sections to match typical brake coil and sensor loads, and crimp-style pin contacts ensure low resistance terminations under vibration.
Wake Industrial offers a 1-year warranty on each cable, can arrange same-day shipping for urgent orders, and maintains a free chat tool for questions on type codes or pin assignments.
