RLC1-013BAB by Bosch Rexroth Indramat

The RLC1-013BAB cable is manufactured by Bosch Rexroth Indramat and is part of the RLC1 Motor Power Cables series. Intended for fixed or moderately flexible installation between IndraDrive amplifiers and servo motors, it delivers phase power and auxiliary signals required for coordinated motion in automated lines. The basic design follows the dimensional and electrical conventions of the series, so the cable fits compatible amplifier-to-motor connections without unusual routing changes. The product ships ready-terminated with series-specific connectors, which helps keep installation orderly in modular production cells. It is suited to applications where the motor cable must remain organized around machine frames, cable trays, or short guided bends.

The cable contains 4x 0.75 mm² + 2x 0.14 mm² conductors arranged under a common jacket. The four power cores each have a cross-section of 0.75 mm², which corresponds to American wire size 18 AWG. Two auxiliary control cores, each sized at 0.14 mm², allow encoder reference or brake release signals to travel beside the main phases without a separate harness. In total, the assembly carries 6 individual copper conductors, which helps keep routing compact in tight enclosures or energy-chain systems. A PVC outer sheath holds the bundle together and guards against coolant splashes. Keeping the power and auxiliary conductors in one jacket also reduces cable clutter between the drive and motor.

Each power conductor is rated for a continuous load of 10.4 A when operated at the stated ambient reference of 40 °C. The insulation system tolerates conductor temperatures up to 90 °C, so the cable maintains dielectric strength during momentary overloads that remain within this thermal ceiling. The thermal rating helps the cable remain stable when load cycles cause periodic heating during normal machine operation. Classified as a Power Cable, the RLC1-013BAB is intended for motor power transmission while also carrying the auxiliary conductors included in the assembly. This layout supports repeated axis movement in automated equipment without requiring a separate parallel harness for basic auxiliary functions.
