Product Description:
The ZK4500-8025-0050 motor cable is produced by Beckhoff and belongs to the ZK Motor Cables series. This assembled connection line combines power, brake, and encoder conductors inside a single sheath, providing a compact link between servo drives and their associated rotary motors. By placing these circuits in one cable, the installation stays organized and the number of separate cable runs is reduced. Within automated production cells, the cable maintains consistent voltage delivery and signal quality while it travels inside drag chains or robot arms, reducing wiring time and helping prevent connection errors.
Electrically, the cable is rated for a continuous system voltage of 1000 V AC, and its three power cores each use copper conductors of 4.00 mm². Differential feedback pairs have a characteristic impedance of 110 Ω ± 10 Ω and are limited to 90 pF/m mutual capacitance to reduce reflection on fast encoder edges. A separate AWG22 signal pair is included for auxiliary functions. The thermoplastic polyurethane jacket resists coolants and abrasion, and it gives the cable an overall diameter of 15.9 mm. The stranding is built to withstand a dynamic tensile stress of 20 N/mm², which supports repeated motion in moving cable systems. The molded Head A connector endures 500 mating cycles without contact degradation.
In strongly articulated axes, the construction accepts a torsional offset of ± 30°/m while moving at speeds up to 4 m/s. The cable has a service life of 5 million double strokes when the installed length is 5.00 m. For controlled stopping, a dedicated brake pair with a cross-section of 1.00 mm² runs alongside the power cores and keeps brake current separate from encoder wiring. This layout helps the cable support motion systems that combine motor power, feedback, and brake functions in one routed assembly.
