Product Description:
The ZK4500-8022-0050 motor cable is produced by Beckhoff as part of the ZK Motor Cables series. It is intended for servo drive installations, linking a drive controller to the motor so that power, brake energy, and feedback signals reach the actuator without separate harnesses. By combining multiple conductor groups under one TPU outer jacket, the cable reduces cabinet penetrations and simplifies routing through energy chains, gantries, and articulated robots found in modern industrial automation.
The three power cores are dimensioned at 1.00 mm² each, while a dedicated brake pair uses a reduced cross-section of 0.75 mm². Encoder or sensor lines are implemented as twisted pairs sized to 22 AWG. All conductors share an insulation system able to withstand up to 1000 V AC, enabling the assembly to support high-torque servo axes without overvoltage stress. Bare copper strands provide low resistance, PP insulation gives dielectric strength, and the surrounding TPU sheath resists oils and weld spatter. The factory-terminated length of 5.00 m suits compact machines, and clearly printed legends ease identification when multiple cables are present.
Mechanical endurance is verified for 5 million drag-chain cycles at operational speeds reaching 4 m/s and horizontal strokes of 20 m. During motion, the copper bundle tolerates a continuous tensile stress of 20 N/mm², rising to 50 N/mm² in static cable trays. Installation flexibility is maintained with a minimum dynamic bend radius of 7 × OD, and the design permits torsional displacement of ±30 °/m so that six-axis robots can rotate without conductor fatigue. A linear weight of 215 kg/km helps damp vibration while keeping carrier loads manageable during continuous motion.
