Product Description:
The ZK1090-3191-0100 motor cable is produced by Beckhoff and belongs to the ZK Motor Cables series. This prefabricated assembly links servo drives with decentralized field devices and is intended for combined power and Ethernet transmission in automated machinery. By integrating an M8 molded plug on one end and an RJ45 plug on the other, it simplifies installation in moving cable chains and supports real-time feedback between motion controllers and I/O nodes on the machine. The combined design also helps keep mobile cable runs organized where both communication and auxiliary power must travel through the same routing path.
At a length of 10.00 m, the assembly spans medium-sized gantries without splices. Its conductors follow a Star Quad layout that preserves pair symmetry and reduces crosstalk for EtherCAT traffic. Differential pairs hold a characteristic impedance of 100 Ω ±15 Ω at 100 MHz, enabling matched termination in Beckhoff drives. Each core uses 19 × 0.1 mm strands, and the Ethernet bundle follows the 1 × 4 × 0.14 mm² (AWG26) profile, giving a loop resistance of 250 Ω/km. A PUR jacket resists oils and endures 20 million flex cycles while containing the 5.4 mm ± 0.3 mm cable in drag-chain runs. The flexible stranded construction also helps the cable tolerate repeated bending while maintaining stable communication during axis motion.
The M8 male plug on the drive side carries 4 A at 40 °C and is cleared for 50 V AC/60 V DC. The RJ45 plug at the controller end permits 1 A at 40 °C and up to 125 V. Propagation delay is 5.55 ns/m, which keeps signal timing predictable across the assembly. The stranded conductors and PUR sheath support high-cycle energy-chain motion while helping preserve both power delivery and data quality. Stable timing and durable insulation are useful where servo axes exchange motion data and I/O signals during constant machine movement.
