RL2-067JBB by Bosch Rexroth Indramat

The RL2-067JBB is a motor power cable manufactured by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It belongs to the Rexroth Cable product group and is intended to supply power between a drive controller and a second-generation servo motor through its factory-fitted M58 power connector. By combining phase conductors and auxiliary signal cores in one assembly, the cable simplifies routing in automated machinery where space and motion limits are strict. This layout helps keep cable paths compact around moving axes and reduces the amount of separate wiring needed at the motor connection.

The power cores are rated for a continuous line-to-line voltage of 600/1000 V, while the integrated signal pair is approved for 450/750 V, allowing mixed-voltage operation inside the same sheath. Each phase uses a cross-section of 16.0 mm², and the overall configuration follows a 4x L + 4x 0.75 mm² layout that keeps power and control circuits in one cable without requiring extra conduits. Insulation resistance exceeds 20 M?/km at 20 °C, which helps limit leakage current over longer runs and supports stable electrical performance. Dynamic applications are supported by more than 5,000,000 bending cycles, allowing repeated travel in energy chains during continuous machine motion. External protection comes from a PUR (Orange RAL 2003) jacket that resists oil, abrasion, and common industrial coolants.

For fixed installation, the cable can be bent to a radius of 5 × D, whereas moving axes require a minimum of 7.5 × D, allowing routing through both static and dynamic sections. Thermal limits are separated by mounting style: fixed runs may reach 90 °C on the conductor, while flexing segments are capped at 80 °C to protect the insulation during motion. The basic cable design omits additional screens, which helps reduce overall weight and supports easier handling in compact carrier systems. The cable is suitable for packaging equipment, transfer lines, and other automated systems that rely on repeated axis movement.
