Product Description:

The RKL4323 motor power cable is supplied by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for servo drive installations, the assembly transfers three-phase power from a controller cabinet to a Rexroth motor while tolerating continuous motion inside cable tracks. Its mechanical and electrical properties make it suitable for high-cycle pick-and-place stations, gantry axes, and other factory-automation zones where dependable energy delivery under constant flexing is critical.

The cable core is engineered for durability, surviving up to 5,000,000 bending cycles in drag-chain service without conductor fracture. Installation rules specify a fixed bending radius of 5xD, while dynamic routing must observe 7.5xD to prevent jacket fatigue; both values relate to the external diameter. That diameter measures 18.5 mm, combining individually insulated power leads and an overall PUR jacket that resists oils, coolants, and weld spatter. Together these mechanical limits define clear routing envelopes and ensure service life in fast-moving machine modules.

Electrical behavior is optimized for low losses and stable drive operation. The copper conductors exhibit a resistance of 3.30 Ω/km at 20 °C, limiting voltage drop over typical machine lengths. A distributed capacitance of 0.8 nF/m minimizes reactive current spikes when the inverter switches at high PWM frequencies. Each phase conductor presents a cross-section of 6.0 mm², supporting the continuous motor current specified for the compatible Rexroth drives. On the motor end, the shielded plug coded RLS1301/C06 mates directly with MSK and MAD motors, shortening commissioning time and eliminating wiring errors.

Wake Industrial offers same-day shipping on this cable for facilities that must restore motion quickly. International shipping options are also available to support plants outside North America. To aid budgeting, quotations issued for the RKL4323 remain valid for 30 days.
