Product Description:
The ZK1090-3131-0030 is a flexible motor cable manufactured by Beckhoff as part of the ZK Motor Cables series. It carries encoder or auxiliary power signals between servo drives and moving axes, allowing coordinated motion in automated machinery and handling systems where continuous flexing and moderate voltages are required. It is intended for installations in which the cable moves with the axis rather than remaining fixed inside the cabinet.
This cable uses a conductor cross-section of 1 x 4 x 0.14 mm² (AWG26) built from a strand bundle of 19 x 0.1 mm tinned-copper wires. That structure keeps loop resistance low while preserving flexibility during repeated motion. The ground capacitance is held to 3400 pF/km, and the loop resistance is limited to 250 Ω/km for predictable voltage drop under the 30 V rating. Mutual capacitance is 51 pF/m at 1 kHz, which helps maintain signal integrity at high encoder frequencies. Additional electrical limits include a signal running time of 5.55 ns/m, a test voltage of 700 V for insulation verification, and an unbalanced resistance tolerance of 2 percent. Polypropylene insulation surrounds each core, and a PUR outer jacket adds oil and abrasion resistance.
The cable is supplied in an overall length of 3.00 m and features braided shielding that achieves 90% coverage to reduce electromagnetic coupling. Mechanical ratings allow dynamic chain installations with continuous accelerations up to 10 m/s² and traversal speeds up to 15 m/s. A polyurethane sheath, combined with the tinned-copper braid, supports repeated bending without jacket cracking, and the polypropylene core insulation sustains low dielectric losses under the 30 V operating voltage. The cable is suited to compact routing inside energy chains or robot arms, where fast signal transfer and durable flex performance are required.
