RL2-045EBB by Bosch Rexroth Indramat

The RL2-045EBB is a power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It forms the power link between an IndraDrive controller and a synchronous servo motor in automated cells. With flexibility matched to moving axes, it delivers constant current while fitting inside standard drag chains. It is intended for servo applications where the cable moves with the machine axis rather than remaining in a fixed conduit. That role requires stable electrical contact during acceleration, deceleration, and repeated positioning cycles. The item belongs to the Rexroth Cable product group and supports layouts that use direct connections instead of intermediate terminal boxes.

The conductor cross-section is 2.5 mm², which helps limit voltage drop while keeping the outer diameter compact. During motion, the jacket can flex to a dynamic bending radius of 7.5 × D, and in fixed trays it holds a static radius of 5 × D. Mechanical endurance reaches 5,000,000 flex cycles, supporting long service in cable carriers. Thermal limits run from -30 °C up to 80 °C, allowing installation in non-climate-controlled areas and storage in warehouse environments. A basic cable design is used, so the insulation layers and screening follow a standard layout without extra liquid-tight jackets, and the drive connection terminates directly at the inverter output.

On the motor side, the harness ends in an M40 circular connector that matches the contacting pattern required by second-generation Rexroth synchronous servomotors. The RL2-045EBB is matched to drive axes that specify MS2x Plug V, so the pin assignment, shielding layout, and strain-relief length fit the motor housing without modification. This arrangement supports direct installation on compatible motors and helps keep routing straightforward in machines where the cable must move with the axis. The connector format also helps maintain a secure mechanical interface during normal machine vibration and repeated travel.
