Product Description:
The RL2-068KBB motor power cable is manufactured by Bosch Rexroth Indramat as part of the RL2 Motor Power Cables series. Designed for the Rexroth Cable product group, this basic-design assembly links a second-generation synchronous motor directly to its drive without intermediate terminal boxes. Within automated machines the cable delivers three-phase power and encoder supply while accommodating continuous movement inside drag chains, making it a critical component for compact, high-cycle axes on packaging lines and gantry loaders.
The mechanical service life is defined by 5,000,000 bending cycles, meaning the conductors can flex that number of times before fatigue limits are reached. During motion the copper bundle conforms to a dynamic bending radius of 7.5xD, so routing paths must respect this minimum loop size to avoid strain. A cross-section of 25.0 mm² allows the power cores to carry currents consistent with the cable’s rated voltage of 600/1000 V, limiting resistive losses across typical drive lengths. The outer sheath is made of PUR, giving abrasion resistance and oil tolerance suitable for plant-floor conditions.
When the installation is fixed, the routing radius can tighten to 5xD, reflecting lower mechanical stress. The integrated signal pair operates at 450/750 V, separating control lines from the higher-energy cores without additional shielding. Continuous conductor temperatures are permitted up to 90 C, so the cable remains thermally stable beside motors or inside sealed enclosures. Visibility in energy chains is improved by the Orange (RAL 2003) jacket color, and the halogen-free compound limits corrosive gas release during any fire event.
