RL2-025CBB by Bosch Rexroth Indramat

Bosch Rexroth Indramat produces the RL2-025CBB power cable as part of the RL2 Motor Power Cables series. Within automated handling lines, this cable transfers three-phase power and auxiliary signals from a drive controller to a servomotor, forming an interconnect that tolerates continuous motion inside cable carriers. By combining motor power and support circuits in one assembly, it helps keep moving harnesses organized where separate cable runs would add bulk. The layout is intended for compact machine routing and continuous axis travel, and it supports cleaner cable paths in enclosed automation spaces.

The cable is rated for 5,000,000 bending cycles, which suits high-duty drag-chain applications. A basic cable design keeps the outer diameter low, while the PUR (Orange RAL 2003) jacket resists cutting oils and remains easy to identify on the factory floor. Power conductors use a cross section of 1.0 mm², which supports low-loss current delivery at the intended load level. During dynamic motion, the assembly must follow a minimum bend radius of 7.5 x D. The power cores are rated for 600/1000 V, and the shielded signal pair is approved for 450/750 V, allowing power and auxiliary circuits to share one routed cable.

Thermal limits allow stationary conductor temperatures up to +90 °C and flexing operation up to +80 °C, so the insulation remains suitable for use near servo housings and inside moving cable chains. The static installation radius is 5 x D, which allows a tighter bend after routing is complete. Compatibility with second-generation motors is supported by a direct-connection layout that mates with standard Rexroth hybrid connectors. The product also sits within the Rexroth Cable group, where it is grouped with related power and feedback harnesses for the same equipment platform.
