Product Description:
The RKL4537 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It transfers drive power and auxiliary control signals between Indramat servo motors and their inverters in automated cells. By combining energy conductors and twisted signal pairs in a single sheath, the cable simplifies routing and maintains electromagnetic compatibility on moving axes.
Designed for dynamic cable chains, the RKL4537 endures up to 5 million flex cycles without conductor fatigue. A sheath diameter of 14.8 mm balances mechanical strength with tight bend radii in confined tracks. Line-to-shield capacitance is specified at 0.7 nF/m; low capacitance limits reactive current and permits longer distances before inverter switching losses rise. Both power and control cores are rated for 600 V AC, giving the assembly uniform insulation coordination. The flexible conductor insulation survives ambient motion temperatures up to 80 °C, preserving dielectric integrity in warm enclosures.
Core materials further define electrical and installation behaviour. The bulk cable is catalogued as INK0602, indicating conductor alloy, strand count, and shield geometry verified for EMC. Its composite layout of 4x2.5 mm² + 2x(2x1.0 mm²)StC supplies three-phase motor current, protective earth, and paired brake or sensor circuits within one jacket. Factory-installed connector shell INS0482 mates directly to Rexroth drive terminals, removing field crimp steps and ensuring correct shielding termination. An outer jacket of PUR (adhesion-free, matte) provides abrasion resistance, resistance to cutting fluids, and easy sliding in drag chains while keeping the surface free from tackiness.
Wake Industrial stocks this cable and can arrange same-day shipping when production lines require immediate replacement. Price quotations remain valid for 30 days to accommodate maintenance budget approvals.
