The Beckhoff ZK4500-0003-0030 is a motor cable belonging to the ZK Motor Cables series and features a length of 3 meters with a test voltage of 4000 V. This cable has a conductor layout of 4 x 1.5 mm² plus 2 pairs of 0.75 mm² made of bare copper, and a PVC jacket for added durability. The cable comes with an 8-pin Head A rated up to 30 amps and a 4-pin Head B, both tailored for specific electrical connections.

Product Description:
The ZK4500-0003-0030 motor cable is supplied by Beckhoff within the ZK Motor Cables series. Intended for servo and spindle connections, the assembly transfers power and feedback between a drive controller and the actuator in automated machinery. Its pre-assembled, keyed connectors reduce wiring time during installation and help maintain signal integrity in dynamic routing chains. This arrangement also avoids field termination at the machine connection points.
At a fixed length of 3.00 m, the cable suits short runs inside a control cabinet or between closely mounted axes. Internally, the conductor bundle follows a 4 x 1.5 mm² + 2 x (2 x 0.75 mm²) layout, where the larger cores deliver motor phase power and the paired smaller cores carry feedback signals. The phase cores can handle a 30 A maximum when connected to the head A plug, which is an eight-pole interface in the M23 format. Polypropylene insulation surrounds each bare copper conductor, and a polyvinyl chloride sheath passes a 4000 V dielectric test. The jacket material is PVC, giving resistance to oils and coolant splash while helping the cable remain flexible over repeated machine cycles. Head B ends with a four-pole plug on 7.62 mm pin spacing, and Head D provides a five-pole feedback link on 3.50 mm pitch for direct connection to Beckhoff servomotors without field crimping.
The cable mass is 224 kg/km, so the delivered three-meter piece adds less than one kilogram to moving-axis payloads, which helps limit added inertia in gantry or robot applications. The signal connector pin grid of 7.62 mm aligns with spring-cage terminal blocks, simplifying panel routing when extensions are required. Inside the paired shielded leads, each feedback conductor has a cross-section of 0.75 mm², which balances voltage drop and flexibility for tight bend radii. Separate power and feedback paths also help reduce crosstalk between high-current and signal channels.
