Product Description:

The RL2-105GBB is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. Intended for second-generation servo motors, it delivers three-phase power and auxiliary conductors in one assembly, reducing cabinet wiring and simplifying routing through drag chains in automated machinery.

The outer jacket is extruded from abrasion-resistant PUR (Orange RAL 2003), and the internal geometry follows a 4x L + 4x 0.75 mm² layout that separates power and signal cores. Each power conductor features a cross-section of 6.0 mm², enabling low resistive loss over extended runs while remaining flexible. System insulation supports a power wire rating of 600/1000 V, so the cable pairs safely with drives that operate on conventional industrial bus voltages. Leakage capacitance is limited to 0.5 nF/m, which helps drive inverters meet EMC limits by minimizing common-mode current.

Mechanical service life is enhanced with a tested minimum of 5,000,000 bending cycles, making the cable suitable for energy-chain applications. Dynamic motion is allowed down to a bending radius of 7.5 x D, whereas static installation can tighten to 5 × D without conductor fatigue. Copper strands tolerate conductor temperatures up to 90 °C in fixed routing and 80 °C in constantly moving sections, supporting continuous duty near servo motors. An overall diameter of 18.2 mm fits standard Rexroth cable glands and drag-chain cross-sections while still delivering the required ampacity.

Wake Industrial stocks this cable, offers same-day shipping when schedules are tight, and keeps quoted prices valid for 30 days to streamline procurement.
