Product Description:
The ZK1090-3191-0020 is a preassembled motor feedback cable produced by Beckhoff within the ZK Motor Cables series. It links servo drives to encoders and I/O modules, carrying both power and high-speed EtherCAT signals between moving axes and the control cabinet. By supplying a factory-terminated harness, the assembly avoids field termination work and maintains the signal consistency required for deterministic motion control in industrial automation. This arrangement is useful in compact machines where reliable communication and clean cable routing are equally important.
Its total length of 2.00 m supports short runs inside machines while keeping slack manageable. The cable is approved for circuits up to 30 V, so low-voltage motor sensors can be powered without additional protection. A controlled impedance of 100 Ω ±15 Ω at 100 MHz helps maintain signal integrity for EtherCAT, and the fine-strand conductor set uses nineteen 0.1 mm wires per core to reduce bending stress during repeated motion. Those strands are made of tinned copper and arranged in a 1 x 4 x 0.14 mm² (AWG26) layout that balances flexibility with current-carrying capability. An M8 4-pin plug on End A mates directly with Beckhoff IP67 field modules. The PUR outer jacket resists oils and weld spatter, and the cable remains compact enough for narrow energy chains because its outside diameter stays within a small range. Shield attenuation of at least 43 dB and a mutual capacitance of 51 pF/m at 1 kHz also help reduce crosstalk between adjacent conductors.
At the controller side, a RJ45 8-pin plug allows direct connection to standard EtherCAT switch ports, completing the daisy chain. The DC loop resistance is limited to 250 Ω/km, which helps keep voltage drop low over the stated cable length. Electromagnetic interference is reduced by a braided screen of tinned-copper wires that provides 90 % optical coverage. With a point-to-point latency of only 5.55 ns/m, the cable supports fast signal transmission in synchronized multi-axis systems. The combination of shielding, low resistance, and stable transmission characteristics makes it suitable for motion applications that require dependable feedback communication during continuous machine operation.
