Product Description:
The ZK1090-3191-0030 is a preassembled industrial cable manufactured by Beckhoff and supplied within the ZK Motor Cables series. As a finished assembly with an M8 A-coded plug on one end and an RJ45 plug on the other, it carries low-voltage motor or sensor signals between field devices and control cabinets. In automated lines, the cable provides a compact connection for decentralized modules while maintaining consistent electrical performance during continuous motion. The factory-terminated ends also remove the need for field assembly and help keep pin assignment consistent between connected devices.
With an overall length of 3.00 m, the assembly reaches from moving axes to stationary controllers without intermediate junctions. Its cores are rated for a nominal voltage of 30 V, which suits extra-low-voltage motor feedback and sensor loops. Each conductor uses a flexible bundle of 19 × 0.1 mm copper wires, so bending cycles in cable tracks create minimal metal fatigue. A loop resistance of 250 Ω/km helps limit voltage drop over longer runs, and the flexible strand structure also supports routing through compact drag-chain paths. The molded M8 connector supports up to 4 A at 40 °C, allowing power and signal transmission through the same cable.
A braided and foil screen provides 90 % coverage, which helps reduce electromagnetic interference when the cable accelerates up to 10 m/s² or reaches travel speeds of 15 m/s inside drag chains. The dual shield arrangement also helps preserve communication quality near motors, drives, and switching components. Signal propagation has a delay of 5.55 ns/m, keeping time-sensitive pulses within controller tolerances. The PUR jacket resists oils and abrasion, and the conductor size of 1 × 4 × 0.14 mm² (AWG26) supports the specified RJ45 continuous current of 1 A at 40 °C. A dielectric strength of 700 V supports insulation integrity during installation surges, and a tightening torque of 0.4 Nm on the M8 nut helps secure the connection without damaging the threads.
