Product Description:
The ZK4000-6100-2020 is a motor supply cable produced by Beckhoff within its ZK Motor Cables series. With pre-assembled connectors and mechanical durability, the cable links a drive controller to a distributed servo motor in an automated machine. By integrating power and feedback conductors in one assembly, ZK4000-6100-2020 reduces wiring effort and ensures consistent electrical characteristics along the motion axis.
At the drive end, the cable uses an M12 circular plug that is A-coded and configured as a 4-pin male interface, so it matches standard EtherCAT P and servo field devices. The four conductors have a cross-section of 4 x 0.5 mm² (AWG20), a size that balances current capacity with flexibility for dynamic routing. Under nominal load, the assembly carries 5 A, while the insulation system supports a rated voltage of 250 V and operation up to 300 V; dielectric integrity is verified at a test voltage of at least 3000 V. Environmental sealing is classified as IP65/67, preventing dust ingress and protecting against temporary immersion when the molded backshell is correctly fastened. This sealing helps the cable transmit power and signal on moving machine axes as well as in enclosed control cabinets.
Mechanical service life is rated for 4 million flex cycles when the installation follows a minimum bend radius of 10 x outer cable diameter. The polyurethane outer jacket, identified as PUR, resists cutting fluids and weld spatter during continuous motion. A connector nut tightening torque of 0.6 Nm secures the threaded coupling and maintains the specified contact resistance over vibration. With a finished length of 2.00 m, the cable can be routed neatly within linear guides or energy chains, and its operating limit of 300 V aligns with low-voltage drive systems common in packaging, assembly, and intralogistics equipment.
