Product Description:
The RL2-066KBB motor power cable is manufactured by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It serves as the primary energy path between 2nd-generation Rexroth servomotors and their drives, delivering phase power and auxiliary signals through a pre-assembled connector so that installation in moving cable tracks is straightforward within automated machinery.
The power cores are dimensioned for a rated voltage of 600/1000 V, so the assembly can be wired directly to converters that operate on standard industrial DC links without additional isolation. A conductor cross-section of 25.0 mm² limits resistive losses and keeps thermal rise low during continuous high-current duty. Separate signal pairs inside the bundle carry encoder reference or brake supply lines and follow a 450/750 V rating to match typical feedback hardware. To support constant motion in energy chains, the cable is certified for 5,000,000 bending cycles, and dynamic routing is possible as long as the bend radius never falls below 7.5 × D; when clamped in a fixed tray, the radius may be reduced to 5 × D. These metrics qualify the cable for multi-shift production where motion cycles accumulate quickly.
The orange outer sheath is made from PUR (RAL 2003), providing abrasion resistance and oil immunity while remaining flexible. A factory-installed connector with size M58 and A/B keying mates to standard IndraDrive motor sockets, eliminating field crimping and preserving shielding integrity. The overall construction follows the basic layout adopted across the RL2 group, with concentric fillers and braid shielding to contain conducted noise. When the cable is laid permanently, copper conductors may reach up to 90 °C; in moving operation they are limited to 80 °C, and ambient service can extend down to -30 °C, enabling reliable use in refrigerated production halls and outdoor handling systems.
Wake Industrial stocks this cable, can arrange same-day shipping when needed, and backs every purchase with a 1-year warranty.
