Product Description:
The ZK4704-0421-2050 motor cable is manufactured by Beckhoff and belongs to the ZK Motor Cables series. It is a preassembled connection lead designed to deliver power and feedback signals between a servo drive and its associated motor inside automated machinery. By combining shielded signal pairs with dedicated power conductors in one assembly, the cable simplifies routing and supports reliable motion-control operation across moving machine axes.
At a fixed length of 5.00 m, the cable can reach most junction boxes without intermediate terminations. A flexible PUR jacket resists oil and coolant exposure, and when the threaded coupling is tightened, the assembly achieves IP66/67 protection for washdown or dusty cells. The three power cores plus protective earth inside Head A are sized to carry 14 A continuously at up to 630 V AC or DC, making the lead suitable for medium-frame servo motors. The molded plug uses a female contact arrangement, and its layout separates the 3+PE power group from the five-pole signal set, while the motor end uses an eight-wire interface with an overall shield that helps maintain encoder integrity near high-frequency switching.
The copper power cores use a cross-section of 0.75 mm² and are terminated by crimp connections that provide stable contact resistance. During reciprocating motion, the construction withstands a dynamic tension of 20 N/mm² and offers a flex life of 5 million bending cycles, supporting continuous movement in cable chains. To avoid conductor fatigue, the routing path must respect a minimum loop of 5 × OD, and the screw-locked connector tolerates up to 500 mating actions before contact wear approaches its design limit. The separate power and signal pin layouts help keep motor power and encoder conductors organized in moving-axis installations.
