Product Description:

The ZK1090-3131-1001 is a motor supply cable assembled by Beckhoff for the ZK Motor Cables series. The component links drive controllers to compact servomotors, providing both power and sensor leads in one routed line. Its short form factor and molded connectors allow integration inside cable carriers and tight control cabinets, making it a common accessory in automated packaging, pick-and-place, and handling stations where space, flexibility, and electrical reliability are required.

This model uses a cross-section of 1 x 4 x 0.34 mm² (AWG22), indicating four equal conductors grouped into a single element for low-power motor phases and feedback lines. The male connector is A-coded and uses M8 geometry, so mating devices can be aligned in a keyed orientation that helps prevent wiring errors. The interface is protected to IP65/67 against dust ingress and temporary water exposure during machine washdown. Its fixed overall length of 0.10 m suits jumper applications between adjacent terminal rails. Seven-strand tinned copper cores and a PUR outer jacket sustain chain movement while carrying up to 4 A at 40°C without excess heating. The conductor bundle follows a 7 × 0.25 mm configuration that maintains flexibility under continuous motion.

The internal arrangement uses a star quad layout, twisting the four conductors into two balanced pairs that minimize crosstalk and keep mutual capacitance at 52 nF/km for stable encoder signals over a 4.5 m travel path. Dynamic stress testing validates a service life of 3 million bending cycles when routed in an energy chain. Signal integrity is further aided by a propagation delay of 5.3 ns/m, keeping motor feedback timing predictable. Installation uses a coupling nut tightened to 0.4 Nm, and the 4-pin arrangement preserves standard IEC pin assignments.
