RLB2-062HDB by Bosch Rexroth Indramat

The RLB2-062HDB belongs to the RLB Motor Power Cables series produced by Bosch Rexroth Indramat. It is a power cable assembly intended to link MS2(X) servo motors directly to ctrlX DRIVE inverters, carrying three-phase supply and protective-conductor lines inside a single sheath. By combining the power conductors and protective conductor in one assembly, it supports cleaner routing through machine frames, drag chains, and cabinet exits. In automated machinery, the cable provides dependable power transmission while preserving electrical and mechanical compatibility between the drive and motor connection points.

This model has a conductor cross-section of 10 mm² to support the current demanded by high-torque MS2(X) motors. For fixed routing, the cable uses a static bending radius of 5 × D, while moving applications in cable carriers use a dynamic bending radius of 7.5 × D. Its flex life is rated for 5,000,000 bending cycles, making it suitable for continuous-motion gantries and pick-and-place axes. The internal conductor layout of 4× L + 4× 1.0 mm² + 2× 1.5 mm² keeps motor phase, brake, and sensor supply lines in one jacket while separating their functions for orderly routing and stable signal support.

The cable operates from -30 to +80 °C, and the storage range matches that temperature window. This range allows use in cold storage areas and hot production cells when the cable remains within its stated limits. It is supplied as a ready-made length, so the terminated ends provide consistent strain relief and shielding continuity at installation. Compatibility with ctrlX DRIVE controllers and the MS2(X) motor family allows direct connection without added interface hardware. That arrangement keeps the motor-to-drive path straightforward and avoids intermediate terminal blocks in the power run.
