Product Description:
The ZK4500-8027-0030 is a flexible motor connection cable engineered by Beckhoff within the ZK Motor Cables series. It is supplied as a pre-assembled cable assembly that links servo drives to matching motors, carrying power, brake, and feedback signals in automated machinery. By integrating power conductors, brake cores, and screened signal pairs inside one jacket, the cable streamlines installation on production lines and minimizes wiring errors in motion-control cabinets.
With a designated length of 3.00 m, the lead suits short-axis or cabinet-to-machine runs. The insulation system withstands an operating voltage of 1000 V AC under UL listing, and the copper power conductors have a cross-section of 10 mm² with a direct current resistance not exceeding 1.91 Ω/km. Dedicated brake cores use a reduced cross-section of 1.50 mm² to actuate holding brakes without excess bulk. Integrated star-quad signaling maintains a characteristic impedance of 110 Ω ± 10 Ω, while pair capacitance is held at 45 ± 15 pF/m to support synchronous encoder links. The overall jacket measures 20.9 ± 0.5 mm in diameter, and composite insulation achieves at least 500 MΩ·km to limit leakage currents. An AWG 22 signal gauge completes the internal layout for differential feedback lines.
Dynamic handling requirements are covered by a service life of 5 million bending strokes in drag-chain guidance, linear velocities up to 4 m/s, and peak acceleration of 30 m/s². The cable can be routed through loops no tighter than a 209 mm radius and has torsional stability of ± 30° per meter along vertical runs. Signal integrity is preserved by shielding coverage of ≥ 85%, which attenuates induced noise during rapid axis reversals. The cable is intended for continuous-duty pick-and-place, gantry, and packaging axes that require motor, brake, and encoder connectivity.
