Product Description:

Beckhoff’s ZK2000-2162-0020 is a flexible motor cable from the ZK Motor Cables series that links servo drives to field-mounted motors in automated machinery. The molded M8 plug on one end and the M12 socket on the opposite end let the cable carry power and feedback over a single lead while keeping panel wiring minimal. Its polyurethane jacket, A-coding, and compact outer diameter support continuous motion tasks on gantries, pick-and-place axes, and other moving-cable assemblies.

The conductor bundle has a length of 2.00 m, giving a fixed reach for short-stroke axes and tool heads without excess slack. Each core has a cross-section of 3 × 0.25 mm² (AWG24), so the cable can carry control-level power without adding bulk. Electrical insulation is rated for up to 300 V, and within this range the three cores may deliver or sense power without dielectric breakdown. Continuous current capability reaches 4 A at 40 °C, allowing typical 24 V auxiliary loads or low-power motor phases to run at full duty while the assembly remains within its thermal limit. A straight M8 three-pin to straight M12 four-pin interface establishes a compact, keyed connection that resists vibration in mobile installations, and contact resistance across the M12 side stays below 10 mΩ to keep voltage drops low.

The cable’s motion limits describe how it behaves on moving carriers. Track speeds can reach 5 m/s and accelerations up to 10 m/s², so drag-chain applications with sharp starts and stops are supported. The jacket diameter is only 4.4 mm, keeping mass and space requirements down, and a minimum bend radius of 6 × outer diameter helps avoid conductor fatigue during routing through tight loops. Dielectric integrity is verified with a test potential of 3000 V, giving a wide margin above the operating voltage and helping the insulation remain intact through mechanical flexing and ambient humidity changes.
