Product Description:
The RKL4762 power cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is intended to connect servo drives to synchronous motors in automated production cells, carrying main three-phase power together with auxiliary conductors for feedback devices, brakes, or thermal sensors. Its molded connectors provide quick installation and minimize wiring errors, so the cable serves as a ready-to-install link between cabinet-mounted inverters and moving axes on packaging machines, transfer lines, and material-handling equipment.
The power cores have a cross-sectional area of 10.0 mm², allowing the cable to conduct the motor’s continuous phase current without overheating. The rated insulation supports drive output voltages up to 600 VAC. When routed in an energy chain, the cable can flex to a minimum dynamic bending radius of 7.5 × D, while stationary installations require a minimum bending radius of 5 × D. The cable has a rated service life of 5,000,000 bending cycles, supporting its use on high-duty linear axes. The assembly is not suited for torsional motion and should not be twisted around its longitudinal axis.
Electrical losses are limited by a conductor resistance of 1.91 Ω/km at 20 °C, helping drives maintain voltage headroom over long cable runs. Two auxiliary pairs are embedded beside the power cores: wires 5 and 6 have a cross-sectional area of 1.0 mm² for low-current status signals, while wires 7 and 8 have a cross-sectional area of 1.5 mm² for brake-release or thermal-switch power. The drive end is terminated with an RLS1302 (C10) molded plug that locks into the inverter, while the motor end connects through an RLK1301 receptacle. The cable uses INK0605 bulk cable with an adhesion-free, matte PUR jacket that provides abrasion resistance and allows smooth movement in drag chains.
