Product Description:
The ZK4500-0023-0100 flexible drag-chain motor cable is produced by Beckhoff within the ZK Motor Cables series. Intended for dynamic routing between servo amplifiers and moving axes, this product combines four 1.5 mm² power conductors with two shielded signal pairs of 0.75 mm² so power and feedback can travel in one line. Its standard assembly length of 10 m suits medium-sized gantries and pick-and-place modules, and the PUR outer jacket resists oils and coolant splash common in automated machining cells.
When installed in an energy chain the cable withstands continuous bending at a minimum radius of 7 × outer diameter, allowing compact carrier layouts without overstressing the copper cores. It remains stable under accelerations up to 30 m/s², so axes that start and stop abruptly do not stretch or fatigue the conductors. Travel velocities may reach 4 m/s over strokes as long as 20 m, and the design endures more than 10 million flex cycles before mechanical failure is expected. A dynamic tensile strength of 20 N/mm² resists longitudinal loads during rapid traverse, and the PUR sheath prevents cable jacket abrasion inside aluminum or polymer guide channels.
Electrically, the core insulation is rated for continuous operation at up to 1000 V AC, and the twisted power pairs exhibit a linear resistance not exceeding 13.3 Ω/km, minimizing voltage drop over extended runs. The overall diameter of 12.4 mm limits fill in standard carrier cavities while still providing room for a braided shield that covers at least 85 % of the circumference to suppress motor-drive EMI. The cable tolerates torsional motion of ± 30 °/m, making it suitable for robotic wrists, and maintains full flexibility between –20 °C and +80 °C during movement without cracking or changing dielectric properties.
