Product Description:

The RLB2-065KEB is a motor power cable manufactured by Bosch Rexroth Indramat for the RLB Motor Power Cables series. It provides the primary energy path between compatible Rexroth MS2 synchronous motors and their drives, carrying phase current and auxiliary power through dynamic machine axes. The integrated cable assembly supports dependable power distribution in automated production cells that require frequent movement and compact routing. Its dedicated conductor arrangement also reduces the need to route separate brake, sensor, or temperature-monitoring wires alongside the main motor leads.

The cable contains four 25 mm² power cores, which carry the output current required by medium-frame servo motors while limiting voltage drop. It also includes four 1.5 mm² auxiliary wires for brakes, sensors, or temperature monitors. This conductor arrangement corresponds to the 4×L + 4×1.5 mm² cabling code and uses the manufacturer’s basic cable design. In continuously flexing drag-chain applications, the sheath can withstand up to 5 million bending cycles. During movement, a minimum dynamic bending radius of 7.5 × D helps prevent conductor fatigue, while fixed routing permits a minimum static bending radius of 5 × D. The cable terminates in an M58 motor connector that connects directly to the corresponding housing on compatible MS2 motors.

The cable can be stored at temperatures as low as -30 °C and can withstand conductor temperatures up to 80 °C during continuous service. Compatibility with the ctrlX DRIVE platform provides the appropriate pin arrangement and shielding for operation with modern inverter systems. Dedicated connector coding supports the MS2(X) motor family and helps prevent connection to an incompatible motor interface. The integrated power conductors, auxiliary wires, shielding, and connector hardware provide a complete cable assembly for direct installation in industrial motion systems.
