Product Description:
The ZK4500-0003-0050 is a motor power and feedback cable assembled by Beckhoff within the ZK Motor Cables series. This prefabricated lead connects servo drives to matching motors, carrying three-phase power, brake conductors, and encoder signals in a single run for automated machinery. By integrating multiple circuits, it simplifies routing in drag chains and supports cleaner cable management on modular production lines.
At a specified length of 5.00 m, the assembly delivers fixed impedance characteristics between the drive and motor. The power cores use a cross-section of 1.50 mm² made from bare copper, supporting continuous currents up to the rated operating potential of 1000 V AC. Polypropylene insulation surrounds each conductor, and the bundle is finished with a PVC jacket; this layering works with the overall outer diameter of 11.7 mm to fit standard energy-chain separators. When the cable moves, the copper and polymer structure tolerates a dynamic tensile stress of 20 N/mm², so accelerated strokes in pick-and-place axes do not exceed the mechanical limit. Total mass is 224 kg/km, a value that affects chain fill calculations.
For stopping control, an integrated brake pair with a cross-section of 0.75 mm² is routed alongside signal pairs that share the same area rating. Position feedback reaches the controller through Head A, an M23, 8-pin molded connector, while the motor end terminates in 7.62 mm four-pin and 3.50 mm five-pin plugs to match Beckhoff servos. Once installed, the cable withstands a static pull of 50 N/mm², enabling use in vertical cable trays without conductor creep over time. Electrical integrity under surge testing is verified at 4000 V. Polypropylene insulation and the PVC sheath keep moisture away from the bare copper strands, maintaining signal fidelity and protecting the 0.75 mm² brake and feedback pairs during continuous operation.
