RLB2-102ECB by Bosch Rexroth Indramat

The RLB2-102ECB cable is produced by Bosch Rexroth Indramat as part of the RLB Motor Power Cables series. It is categorized in the Rexroth Cables product group and serves as a power link between the motor-side terminal box and a junction cabinet in ctrlX DRIVE systems. By carrying drive output to compatible synchronous motors, the assembly supports closed-loop speed and torque control in automated axes. Its construction maintains the insulation system and conductor layout needed for industrial motion duty during repeated machine cycles. This arrangement lets the cable serve as the motor-side segment in modular machine wiring.

The cable is rated for 5 million flex cycles, so it can withstand continuous motion in energy chains or robotic dress packs without early conductor fatigue. A conductor cross section of 2.5 mm² supports the current demand of midsize servo motors while helping limit voltage drop over the cable run. During dynamic travel, a minimum bend radius of 7.5 × D helps prevent kinking, while fixed installation permits a tighter radius of 5 × D. The assembly uses four load conductors and four 1.0 mm² auxiliary cores, and the motor end terminates in a T (M32) terminal box interface that mates directly with the motor housing.

This cable is supplied as a ready-made assembly, which removes the need for field connector crimping and helps maintain shielding continuity across the prepared cable section. It can operate up to 80 °C and remains pliable down to -30 °C, allowing use in machines exposed to heat during washdown or low temperatures in storage areas. The design supports the ctrlX DRIVE controller family and is matched to the MS2(X) motor series for impedance and pin assignment. It is intended for the motor-to-junction portion of a multi-section harness, where a separate cable segment can be used between the junction cabinet and the drive.
