Product Description:
The ZK1090-3131-0100 is a pre-terminated motor feedback cable from Beckhoff’s ZK Motor Cables series. Designed for use in motion control and distributed I/O assemblies, the cable links encoders or other low-power sensors to a control cabinet while flexing inside drag-chain installations. Both ends are fitted with M8 plugs that align to the A-coded pin layout, allowing quick replacement without crimping. A star-quad pair arrangement inside the polyurethane jacket maintains balanced signal transmission and limits crosstalk caused by high-frequency switching equipment.
The cable operates on a maximum potential of 30 V, matching the extra-low-voltage level typically supplied by encoder interfaces. Star-quad geometry coupled with a characteristic impedance of 100 Ω ±15 Ω (100 MHz) supports differential signaling and minimizes reflections on fast serial links. Total length is 10.00 m, providing adequate reach between a moving axis and a stationary controller without exceeding the impedance budget. Despite this reach, the assembly maintains a compact outer diameter of 5.4 mm ±0.3 mm, which simplifies routing through cable carriers and cabinet glands. The molded connector shells and continuous PUR sheath achieve a protection category of IP65/67, so the interface remains sealed against dust ingress and temporary water exposure in washdown areas.
The cable uses a conductor cross-section of 1 × 4 × 0.14 mm² (AWG26), formed from 19 strands of 0.1 mm copper that balance flexibility with conductor strength. A braided screen of tinned copper provides 90 % optical coverage, giving low transfer impedance when the cable is routed beside motor power conductors. The loop resistance is 250 Ω/km, which helps keep voltage drop low across the cable run. For high-frequency edges, a signal propagation delay of 5.55 ns/m helps predict timing skew in multi-axis systems while staying within fieldbus timing constraints.
