Product Description:
The ZK4500-0004-0070 cable is produced by Beckhoff within the ZK Motor Cables series. It is supplied as a hybrid motor lead that carries drive power and encoder signals between a servo amplifier and its matched motor inside automated production cells. Combining multiple conductors in one sheath reduces panel space, shortens installation time, and keeps the motor-to-controller link electrically consistent during continuous machine movement. Using one cable for both power and feedback also helps keep moving cable paths compact on servo axes.
This assembly is delivered in a fixed length of 7.00 m. Inside the jacket, a 4x2.5 + 2x(2x1) mm² conductor set provides separate paths for phase current and feedback lines, matching typical low-voltage servo layouts. This layout keeps motor power and low-level feedback circuits in the same cable while separating their conductor paths. The power cores can carry up to 30 A and withstand phase-to-phase or phase-to-ground stress up to 630 V AC/DC, while the overall dielectric spacing supports a system potential of 1000 V AC. Bare copper strands limit power losses; their resistance is held to ≤7.98 Ω/km, and the paired signal cores are limited to 19.5 Ω/km to help preserve encoder accuracy. Polypropylene insulation and a PVC outer sheath work with a specified insulation resistance of 10 MΩ·km to restrict leakage currents. During flexing cycles, the cable tolerates a dynamic tensile load of 20 N/mm² without conductor breakage.
An outer diameter of 13.4 mm ±0.4 mm fits standard drag-chain clamps, and a braided screen with ≥85% optical coverage shields both power and data conductors from electromagnetic noise. The construction survives static pulls up to 50 N/mm² and torsional motion of ±30 °/m, so it can be used on rotary axes or robots. PP insulation and the PVC jacket maintain flexibility and help resist coolant splashes and general shop contamination.
