Product Description:

The RL2-066HBB motor power cable is produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It connects second-generation motors to their inverters, carrying both power conductors and four 0.75 mm² signal cores defined by the 4× L + 4× 0.75 mm² cable type. The assembly belongs to the Rexroth Cable product group and is supplied with an M58 motor-side connector, allowing direct mating without field crimping. A basic internal layout and a PUR outer jacket in orange RAL 2003 give abrasion resistance and visibility on automated production lines.

The cable is rated for mechanical motion common to robotics and gantry axes. It tolerates torsional stress of ±30 °/m along its length and endures up to 5 million bending cycles before fatigue limits are reached. During continuous flexing, a minimum dynamic loop of 7.5 × D is required, while static routing can tighten to 5 × D without sheath damage. The copper power cores have a cross-section of 10.0 mm², supporting thermal dissipation when full-load current is applied. For drive outputs, the insulation system sustains a conductor-to-conductor operating voltage of 600/1000 V, so cabinet components can be specified to the same category.

The auxiliary signal pair is separated from the power bundle and carries encoder or brake supply lines up to 450/750 V. Insulation resistance is not less than 20 MΩ/km at 20 °C, reducing the risk of leakage currents on long drag-chain runs. When permanently installed, the cable functions between -30 to +80 °C; in moving tracks it remains flexible from -20 to +60 °C. These temperature envelopes, combined with the PUR jacket and the specified static bending radius, allow the RL2-066HBB to operate in press, packaging, and material-handling cells without additional environmental shielding.
