Product Description:
The RL2-066JBB is a motor power cable produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It links second-generation IndraDrive or MSK motors directly to compatible drives, supplying three-phase power and protective earth without intermediate junctions. In automated cells, this cable carries rated current to the motor while maintaining electromagnetic compatibility between cabinet inverters and field-mounted servomotors. Its layout is intended for servo installations that need a direct cable run between the cabinet and the motor location.
The conductor bundle uses 6 AWG copper, which corresponds to a cross-sectional area of 16.0 mm². This conductor size affects resistive voltage drop along long machine axes and helps keep current transfer stable over extended cable runs. Based on that geometry, the cable can carry up to 71.3 A continuously without exceeding permissible thermal rise. During dynamic motion in cable chains, the minimum bend radius is 7.5 × D, so energy-guiding troughs must follow that radius to avoid conductor fatigue. A molded M58 Power Connector is factory-installed, allowing plug-in power delivery to the motor from the drive. The cable is listed as Basic in the Rexroth Cable product group and supports direct connection to second-generation motors without adapter boxes.
For repetitive machine cycles, the insulation and shielding are rated for 5,000,000 flex motions, which suits high-duty linear gantries and other equipment with constant travel. Internal phasing follows 4 x L + 4 x 0.75 mm², combining four power conductors with four smaller cores for temperature sensor signals. When stationary, the cable may be coiled to a tighter radius of 5 × D without risking microcracks in the insulation system. Ambient service is approved from -30 to 80 °C, and the cable can be stored within the same temperature range.
