Product Description:

The RLB2-065KEB cable is a motor power lead from Bosch Rexroth Indramat’s RLB Motor Power Cables series. Designed for MS2(X) servo motors, it carries three-phase energy between a ctrlX DRIVE inverter and the motor while also routing auxiliary logic lines. The basic construction, shielding, and industrial jacketing allow reliable transmission of current in dynamic drag-chain environments commonly found in automated packaging, handling, and assembly cells. Together with matched encoder lines, it completes the motor connection set recommended for next-generation Rexroth platforms.

It incorporates 4 × 25 mm² copper cores for the main phases and an additional 4 × 1.5 mm² set for brake or sensor supply. The jacket is tested for 5 million flex cycles, a value that suits high-frequency gantry or robot axes. During motion, the cable may bend to a minimum arc of 7.5xD without fatigue, while stationary installations can observe a tighter 5xD radius. These figures explain why the lead endures constant torsion yet maintains insulation integrity.

Thermal performance spans from -30 °C up to 80 °C, permitting outdoor or chilled-room mounting as well as warm control cabinets. A threaded M58 motor connector mates directly to MS2(X) stators and seals against oil splash. Compatibility with the ctrlX DRIVE platform simplifies wiring layouts, because identical pinouts handle feedback and power through unified terminal blocks. The basic design combined with a 4L plus auxiliary layout reduces impedance rise during acceleration, limiting voltage drop across long machine bridges.

Wake Industrial stocks this cable in multiple lengths. Same-day shipping is available when rapid replacement is needed. Quotations remain valid for 30 days to aid maintenance budgeting.
