The Bosch Rexroth Indramat RL2-044FBB is part of the RL2 Motor Power Cables series and is designed with basic cable construction featuring 4x L and 4x 0.75 mm² wires, plus a 4.0 mm² cross section. It uses PUR jacket material and PP insulation, supports up to five million bending cycles, and has a dynamic bending radius of 7.5 times the cable diameter. This cable is suitable for rated power voltages of 600/1000 V and is built for use with second-generation motors.

Product Description:
The RL2-044FBB is a motor power cable produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It is intended to link 2nd-generation Rexroth servo motors with their drive controllers, carrying both power and auxiliary signals through one assembly. In automated machinery, the cable forms the physical path for drive current and feedback conductors in a single run, simplifying routing in cable tracks and reducing installation time on multi-axis systems.
The cable is rated for 5 million flex cycles, so it can be placed in continuously moving energy chains without premature conductor fatigue. A dynamic installation requires a minimum bend of 7.5 × D, while stationary routing may follow a tighter 5 × D radius; these limits protect the PP-insulated cores from mechanical stress. Each power conductor has a cross-sectional area of 4.0 mm², sized to handle motor currents without exceeding permissible voltage drop or thermal rise. When energized, the assembly withstands a drive potential of 600/1000 V on the power pair and up to 450/750 V on the signal cores, allowing one hybrid cable to serve both torque-producing phases and low-level sensor lines in compliance with industrial low-voltage rules.
The outer sheath is molded from PUR (orange RAL 2003), giving abrasion resistance and high visibility inside machine enclosures. Under fixed mounting, the cable remains serviceable up to +80 °C, while moving applications are limited to a low-temperature floor of −20 °C to prevent jacket cracking. Conductor strands may reach 90 °C during overload yet stay within the listed maximum conductor temperature for fixed runs. These thermal boundaries, together with the specified bend radii and cycle life, support routing the cable in pick-and-place modules, gantries, and other high-duty automation axes.
