Product Description:
The ZK4500-8022-0020 is a flexible motor cable produced by Beckhoff for the ZK Motor Cables series. It carries both power and encoder feedback between a servo drive and a moving axis, allowing coordinated motion in automated packaging lines, gantries, and material-handling cells. By combining power cores and signal pairs in a single jacket, the cable simplifies routing inside energy-chain assemblies and maintains consistent electrical characteristics along the entire run.
For fixed installation, the minimum bend radius is 5 × OD, while dynamic routing in drag chains requires a radius of seven times the outer diameter to reduce conductor fatigue. The assembly is supplied in a factory-terminated length of 2.00 m, and its conductor arrangement of 4×1 mm² + 2×0.75 mm² + 2×AWG22 separates motor phases, protective earth, brake supply, and differential encoder signals. A rated insulation strength of 1000 V AC supports connection to servo inverters without additional conduit. The outer sheath is molded from TPU, giving high abrasion resistance and oil tolerance, and the design mass of 215 kg/km helps keep moving inertia predictable in cable carriers. Static tensile resistance reaches 50 N/mm², and the permitted dynamic tensile load is 20 N/mm², so the cores remain dimensionally stable during rapid traverses. Termination on side A uses a Power 3 + PE connection plus five-pole feedback, while side B uses an M23 interface with a 7.62 mm pitch that matches Beckhoff servomotor receptacles.
This construction endures continuous motion up to a speed of 4 m/s and an acceleration of 30 m/s². Endurance testing confirms a life of 5 million bending cycles, matching high-duty repetitive motion. Horizontal carrier lengths can extend to 20 m, and vertical travel of up to 5 m is allowable without additional strain relief. The cable is intended for continuous travel in energy chains rather than fixed cabinet wiring alone.
