Product Description:

The RL2-002CBT is a motor power cable manufactured by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It is intended to route three-phase power from a drive to a second-generation Rexroth motor while tolerating continuous torsional movement inside articulated robot arms and other dynamic axes in industrial automation. The construction and connector geometry allow the cable to be installed quickly between the controller cabinet and the motor housing without additional adapter hardware, providing a dedicated link for both power conductors and auxiliary signal cores.

The cable carries four load conductors and four auxiliaries arranged as 4x L + 4x 0.75 mm²; the load cores each use a 1.0 mm² cross-section that matches the conductor make-up of 4×1.0 + 4×0.75 mm². Its insulation system offers a resistance of ≥ 20 MΩ/km, reducing leakage current over long runs. Power cores are rated for 600/1000 V, while the signal pair is qualified for 450/750 V, so separate feedback wiring is unnecessary in typical servo installations. The round profile measures 12.2 mm in diameter and can be clamped or routed through standard cable chains. When fixed in place, the sheath can be bent to a radius of 5 × D, enabling compact cabinet layouts without exceeding mechanical stress limits on the copper bundle.

The torsion-optimized design withstands cyclic twists of ±180°/30 cm, making it suitable for joints that rotate back and forth during every machine cycle. Electrical performance is further stabilized by a distributed capacitance of 0.4 nF/m, limiting reactive load on the drive inverter at high PWM frequencies. Its outer sheath is manufactured from PUR (Orange RAL 2003), giving abrasion resistance and easy visual identification within mixed cable trays. At the motor end, an integrated M17 Power Connector mates directly with Rexroth Generation 2 motors, allowing the product, listed under the Rexroth Cable group, to complete a sealed power interface without additional gaskets or strain-relief adapters.
