Product Description:
The ZK1090-3131-1020 motor cable is produced by Beckhoff for the ZK Motor Cables series and is intended to connect servo amplifiers to small-frame motors in automated handling equipment. Supplied in a 2.00 m length, the assembly is finished with an M8 male straight 4-pin A-coded connector so it can be routed through tight carrier chains without field terminations. A PUR outer jacket resists cutting fluids and abrasion, while an overall copper braid provides continuous electromagnetic shielding. The cable supports up to 4 A of load current at 40 °C under normal duty.
Inside the cable, the conductor set uses 1 × 4 × 0.34 mm² (AWG 22), a cross-section large enough to limit voltage drop on decentralized drives. The core layout follows a star quad geometry, so differential signals share equal electrical lengths and crosstalk is minimized. Individual conductors are stranded with 7 × 0.25 mm wires for flexibility, allowing continuous motion at line accelerations up to 4 m/s² without conductor fatigue. Dynamic life is rated for 3 million bending cycles, and the specified mutual capacitance of 52 nF/km helps keep impedance matched for fast drive switching edges. At 1 kHz, the signal delay is 5.3 ns per meter, supporting encoder transmission over the short link between a local drive and its connected motor.
For continuous drag-chain service, the assembly is rated for cable-carrier speeds up to 4 m/s across strokes as long as 4.5 m. The straight M8 coupling is designed for a tightening torque of 0.4 Nm, which helps prevent thread damage while maintaining a secure connector fit. During motion, the specified unbalanced capacitance of 1600 pF/km helps keep common-mode noise low so resolver or brake channels remain stable. These limits apply when the cable is looped through multi-axis pick-and-place or gantry stages, where repeated motion and stable electrical behavior are both required.
