Product Description:
The RKL4523 is a motor power cable manufactured by Bosch Rexroth Indramat and supplied within the RKL Motor Power Cables series. Designed for servo axes, the cable links drive controllers to motors while carrying both power and auxiliary control conductors, allowing motion systems to operate reliably in demanding automation cells and flexible handling modules.
A nominal outer diameter of 18.5 mm determines gland sizing and ensures proper strain relief. When routed in static trays the cable may be bent down to 5 × D, while dynamic drag-chain runs require a minimum loop of 7.5 × D; these limits prevent conductor fatigue and jacket cracking. The bundled conductors follow the arrangement 4x6.0+(2x1.0)StC+(2x1.5)StC mm², combining three-phase motor leads, protective earth and shielded signal pairs inside one sheath. Copper losses across long distances are moderated by a resistance of 3.30 Ω/km, supporting accurate voltage at the motor terminals during acceleration peaks.
The auxiliary pair is rated for 600 V AC, matching the power cores and simplifying cabinet fusing. A rugged PUR (adhesion-free, matt) jacket resists oils and welding spatter, so the assembly endures continuous flexing on gantry axes. For permanently installed sections, conductors may reach up to +90 °C without derating, whereas moving cable chains are limited to +80 °C to preserve insulation life. These electrical and thermal margins complement the mechanical limits outlined earlier, giving designers a clear operating envelope for both stationary and high-cycle applications.
