Product Description:
The RL2-166LBB is a motor power cable supplied by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It serves as the dedicated link between a drive controller and a second-generation Indramat motor, carrying power and low-level feedback signals in automated machinery. By combining large conductors for phase current with smaller signal pairs, the cable streamlines wiring inside moving axes and helps maintain electromagnetic compatibility on assembly lines, gantries, and robotic cells.
The cable is rated for a minimum of 5,000,000 bending cycles, supporting continuous motion in energy chains. A conductor cross section of 35.0 mm² allows the power cores to deliver high motor current without excessive voltage drop. Its torsional capability of ±30°/m permits rotation around the cable axis on articulated joints. The power insulation withstands up to 600/1000 V, providing sufficient capacity for typical 400 V AC drives. During dynamic operation, the cable requires a minimum bend radius of 7.5 × D, which establishes the routing limit inside compact cable tracks. The cable also has a Basic design and PP core insulation that resists moisture.
The internal layout consists of four load conductors and four 0.75 mm² conductors arranged according to IEC color codes. The four smaller conductors form two shielded signal pairs that share the sheath with the load cores, reducing the overall bundle diameter. A flame-retardant and oil-resistant PUR jacket in RAL 2003 orange protects the assembly against coolants and cutting fluids. Insulation integrity is maintained with a minimum resistance of 20 MΩ/km at 20 °C. The motor end terminates through an E (M50) terminal box, while the opposite end is prepared for drive-side connectors. The signal cores can operate at 450/750 V, and fixed routing permits a bend radius of 5 × D without stressing the PP insulation.
