RL2-023CBB by Bosch Rexroth Indramat

The RL2-023CBB cable is produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series and belongs to the Rexroth Cable product group. It serves as the power link between a drive controller and its matched actuator, carrying three-phase supply lines and auxiliary conductors through moving drag-chain tracks. The cable is intended for moving applications where power and auxiliary circuits must remain stable during repeated axis travel. Its conductor arrangement suits second-generation Indramat motors and provides the flexibility needed for continuous travel in pick-and-place assemblies, gantry modules, and packaging stations.

This model is rated for up to 5,000,000 bending cycles, which indicates long service under constant reciprocating motion. Mechanical stress is limited by a dynamic bending radius of 7.5xD, and this limit applies whenever the cable moves through chain links or rolling supports. The conductor layout of 4x L + 4x 0.75 mm² includes the main power paths, a protective earth conductor, and four auxiliary conductors. A cumulative copper area of 1.0 mm² for the live cores supports the cable's electrical load capacity while keeping the assembly compact. The outer jacket keeps the overall diameter low, which helps reduce drag-chain fill and surface friction during motion. The cable remains usable from -30 °C to 80 °C.

When the cable is fixed to a cabinet wall or motor junction box, a minimum static bending radius of 5xD is permitted to reduce long-term conductor stress. An M23 Power Connector is molded to the motor end, so the cable attaches with a twist-lock connection rather than separate field wiring. Compatibility with the manufacturer's 2nd motor generation keeps the electrical pinout and keyed shell alignment consistent with matching motors. This supports proper mating at the motor interface without altering the intended connector orientation.
