Product Description:

The RL2-542GBB is a motor power cable in the RL2 Motor Power Cables series from Bosch Rexroth Indramat. Designed for the 2nd motor generation, it routes three-phase power and auxiliary signals between drive inverters and moving axes in automated machinery. The cable belongs to the Rexroth Cable product group, so its mechanical and electrical parameters match standard routing hardware in modular production lines. By combining load conductors and control pairs in one PUR-sheathed bundle, it simplifies installation and reduces panel space. The orange RAL 2003 jacket also provides clear circuit identification on the shop floor.

Inside the Basic design, four 6 mm² power cores and two shielded signal pairs follow the conductor build 4x6.0+(2x1.0)+(2x1.5) mm². The layout supports up to 5,000,000 bending movements in energy-chain duty and maintains phase balance through the stranded geometry. Its specified cable type of 4x L + 4x 0.75 mm² assigns separate auxiliary wires for brake release or temperature sensors. Each power core has a cross-section of 6.0 mm², enabling low resistive losses while carrying currents associated with drives rated to 600/1000 V. Continuous operation is admissible up to 90 °C in fixed routing and 80 °C when flexed, so enclosure heating does not exceed insulation limits.

The pre-moulded connector option uses size M40 to couple directly to motor terminal boxes without field crimping. A leakage capacitance of 0.5 nF/m keeps common-mode currents low, supporting EMC compliance for fast-switching inverters. Installation clearance is predictable because the fixed installation bend limit is 5 x D and rises to 7.5 × D in dynamic loops. With an outer jacket diameter of 18.2 mm, the cable fits standard clamp glands while the PUR sheath resists oil and weld spatter. Separate signal cores withstand 450/750 V, and the orange outer layer preserves visibility even after prolonged plant service.
