Product Description:

The ZK4500-0003-0080 is a motor power and feedback cable produced by Beckhoff within the ZK Motor Cables series. It links servo drives to field-mounted motors and transmits both three-phase power and low-level sensor signals, ensuring coordinated motion in automation cells and machine tools. By integrating power conductors, signal pairs, and shielding in a single assembly, the cable simplifies routing inside drag-chain channels and control cabinets.

The cable is supplied in a fixed length of 8.00 m, allowing direct point-to-point installation without intermediate junctions. Its molded connector on the drive side uses the M23 interface, a common circular form that mates with Beckhoff servo amplifiers and maintains contact integrity under vibration. For power conductors, a cross-section of 1.50 mm² is used to balance current capacity with overall flexibility. Feedback and auxiliary lines use a 0.75 mm² conductor pair that supports encoder or brake circuits while minimizing bundle diameter. The assembly tolerates up to 1000 V AC between cores, which provides margin for transient overvoltage events. Bare copper conductors with PP insulation and a PVC outer jacket resist oils and common coolants, while the power wire resistance remains below 13.3 Ω/km to limit voltage drop.

The dielectric system delivers an insulation resistance of ≥ 500 MΩ·km, which helps limit leakage currents in long multi-axis runs. A tinned-copper braid and foil provide ≥ 85 % overall shield coverage so that switching noise from adjacent drives does not couple into encoder lines. The cable supports a dynamic tensile load of 20 N/mm² and a static limit of 50 N/mm². During high-potential testing, each conductor withstands 4000 V without breakdown, confirming adequate spacing and material performance. At 224 kg/km, the cable weight supports orderly routing while maintaining the stiffness needed for fixed installation.
