Beckhoff Automation ZK1090-3131-3040 EtherCAT Cable

Beckhoff ZK1090-3131-3040 is a 4.00 m PVC-fixed EtherCAT pre-assembled cable with M8 male straight 4-pin A-coded connectors on both ends, engineered for reliable, plug‑and‑play connections between Beckhoff EtherCAT devices in industrial automation. The cable uses AWG26 conductors and features shielding on both ends to suppress electromagnetic interference in harsh environments. Its electrical data include a rated voltage of 50 V AC / 60 V DC and a current rating of 4 A at 40 °C, along with insulation resistance of at least 100 GΩ, and installation torque for the fixing nut of 0.4 Nm. This 3040 variant belongs to the ZK1090-3131-3xxx family, which offers multiple fixed-installation lengths; the 3040 designation confirms the 4.00 m length. The M8 connectors are straight, 4-pin, and A-coded, making it suitable for connecting EtherCAT masters to slaves or other fieldbus devices in control cabinets, robotics, conveyors, and broader automation projects where a compact, shielded cable is required.
