Product Description:
The ZK4704-0421-2030 is a factory-assembled motor cable produced by Beckhoff within the ZK Motor Cables series. It links servomotors to drive controllers. The cable carries both power and feedback signals, streamlining installation in automated machinery and gantry systems.
The cable offers a reach of 3.00 m, enough for typical cabinet-to-axis routing without excess slack. Rated at 630 V AC/DC and 14 A on the power cores, it supports standard Beckhoff servomotor current draw while maintaining voltage integrity over the full length. A fixed bending radius of 5 x outer cable diameter prevents conductor fatigue when the harness is tied down inside machine frames. In dynamic cable chain applications, its outer sheath withstands accelerations up to 4 m/s, allowing fast axis motion without snagging. Copper conductors with a 0.75 mm² cross-section deliver the required ampacity, and the AWG22 signal pairs remain separate from the power bundle to limit crosstalk.
The PUR jacket is molded for IP66/67 protection when the bayonet-locked plug is fully tightened, blocking dust ingress and high-pressure washdown during maintenance. Internal materials are rated for 5 million flex cycles, so the assembly can endure long service intervals in continuous bend tracks. Separate contact layouts of 3+PE / 5 isolate motor phases from encoder lines, and the shielding around the 8-wire plus braid bundle limits EMC emissions. The outer covering is composed of PUR (Polyurethane), which resists cutting oils and welding sparks. A female plug equipped with crimp contacts mates directly to Beckhoff servo connectors, and the opposite end uses the same housing style. The bayonet locking method secures the connection, and crimp terminations maintain stable resistance throughout the cable's life.
