Product Description:
The RKL4718 is a flexible motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It links a Rexroth drive to the terminal box on a synchronous or asynchronous servo motor, carrying three-phase power and auxiliary signals through a factory-assembled harness. The cable is intended for cable-chain and moving-axis installations in industrial automation, where continuous motion and high cycle counts demand consistent electrical performance and abrasion-resistant insulation.
Power transmission is handled by three phase conductors, each with a cross-sectional area of 2.5 mm², enabling the drive to deliver rated current without excessive voltage drop. Control and feedback connections are supported by four auxiliary conductors, each with a cross-sectional area of 1.0 mm²; these cores can serve brake releases, temperature sensors, or encoder power supplies. At the drive end, the assembly terminates in an RLS0723 (K03) circular connector that locks directly to the inverter’s power output. The opposite end is prepared for an RLK1301 terminal box, allowing the conductors to be connected inside the motor housing. The overall bundle includes a green-and-yellow grounding conductor sized like the phase conductors, and the direct wiring arrangement eliminates intermediate junctions that could add resistance or potential failure points.
The cable is rated for 5,000,000 continuous bending cycles, allowing it to operate in high-speed gantries and pick-and-place robots without premature conductor fatigue. During motion, the jacket can flex around a dynamic radius of 7.5 × D, while stationary loops can rest at a tighter 5 × D radius to reduce the required routing space. The outer sheath remains pliable from -30 °C to 80 °C, helping the cable maintain its insulation integrity in unheated warehouses, refrigerated processing areas, and warm production environments that approach its upper temperature limit.
