Internal Product Review
The ZK4500-8003-0070 is a Beckhoff ZK motor cable with an M23 interface and a 1000 V AC maximum operating voltage. Bare copper conductors and a PVC jacket support clean signal integrity and dependable service in industrial motion systems. A 1.50 mm² power cross-section paired with AWG22 signal conductors makes the cable a strong choice for servo installations.

Product Description:
The ZK4500-8003-0070 is a pre-assembled motor cable produced by Beckhoff for the ZK Motor Cables series. Designed for servo drive installations, the assembly carries power, brake supply, and low-level signals between a controller and its motor, simplifying routing inside automated production equipment and ensuring consistent electrical characteristics over the specified length. It is intended for fixed or flexed machine sections, where a single hybrid line reduces panel openings and minimizes electromagnetic coupling among separate conductors.
In this variant, the total length is 7.00 m, allowing placement of a drive up to seven meters from the actuator without intermediate junctions. Each of the three power cores is sized at 1.50 mm², while the dedicated brake pair is 0.75 mm²; these conductor areas help limit voltage drop under typical servo currents. For insulation, polypropylene surrounds the individual wires, and a polyvinyl chloride outer jacket shields the bundle from coolants and abrasion. The stranded conductors use bare copper for low resistance. The rated insulation withstand is 1000 V AC, so the cable can feed motors on high-power three-phase systems. When clamped, the assembly tolerates a maximum static tensile stress of 50 N/mm², and it should be laid with a bending radius of at least 61 mm to maintain conductor integrity.
The electrical layout follows the composite scheme 4 x 1.5 mm² + 2 x 0.75 mm² + 2 x AWG22, so power, brake, and feedback lines share one sheath. At the drive side, an M23 connector uses the Power 3+PE; Signal 5 pattern, while the opposite ends terminate in a 4-pin power plug and a 5-pin feedback plug for standard Beckhoff motors. Under repetitive motion, the cable tolerates a dynamic axial stress of 20 N/mm², making it suitable for drag-chain routing. The outer sheath remains flexible and abrasion-resistant on moving axes, while the dedicated signal pair carries encoder data apart from the higher-current conductors.
