Product Description:

The RL2-166LBB motor power cable is produced by Bosch Rexroth Indramat as part of the RL2 Motor Power Cables series, itself listed in the Rexroth Cable product group. Built with a Basic design and a 4x L + 4x 0.75 mm² layout, the assembly connects second-generation motors that use an E (M50) terminal box to their drives, supplying three-phase power and auxiliary signals in dynamic industrial automation axes.

Mechanical durability is a key feature: the cable is rated for 5,000,000 bending cycles, allowing continuous motion in cable tracks without premature conductor fatigue. The copper bundle follows a conductor make-up of 4x35 mm² plus 2x(2x1.5 mm²), and each strand is insulated with PP to maintain dimensional stability under heat. A cross-section of 35.0 mm² in the power cores minimizes voltage drop at high current densities. During installation the assembly tolerates a torsional load of ±30°/m, while minimum bend radii of 5xD for fixed routing and 7.5xD for dynamic routing help prevent kinking and internal shield damage.

Electrical integrity is supported by a tough PUR (RAL 2003) outer jacket that resists coolants and abrasion. Power conductors operate safely up to 600/1000 V, and the paired signal leads are insulated for 450/750 V control potentials, keeping feedback lines isolated from high-energy phases. A measured insulation resistance of 20 MΩ/km at 20 °C limits leakage currents, while polypropylene insulation and the specified conductor make-up further control capacitive coupling across long runs.

Wake Industrial stocks this cable and offers same-day shipping when orders are placed before the daily cutoff. Every purchase is backed by a 1-year warranty that covers workmanship and component reliability. For budgeting purposes, written quotations remain valid for 30 days.
