GM400.020A102 SSI Codeur absolu Custom Replacement Solution

We provide a professional 1:1 customized replacement solution for the GM400.020A102 encoder, ensuring complete compatibility with the original Baumer design. By reproducing all critical dimensions, electrical interfaces, and mounting provisions, our solution allows for direct replacement without any modifications to the existing system. With a rapid production cycle of 10–15 working days, this solution enables operators to secure quick delivery, reduce downtime, and maintain continuous operation in wind turbine and industrial automation applications. The custom replacement provides a reliable and cost-effective alternative to extended lead times often associated with OEM components, helping customers sustain efficient and uninterrupted workflows.

The GM400.020A102 replacement encoder is a multiturn SSI absolute encoder utilizing optical sensing for accurate position measurement. With up to 14-bit resolution per revolution for singleturn operation and 16-bit multiturn capability, it delivers precise and stable feedback for wind turbine pitch and yaw control, as well as industrial motion applications. It is fitted with a clamping flange for secure mounting, includes electronic zero-point adjustment for easy setup, and features a counting direction input for integration flexibility. Additional incremental output signals are available to extend control options. Built with strong magnetic field resistance, the encoder ensures reliable performance in environments with high electromagnetic interference, such as turbine nacelles, heavy machinery, or automated production lines, ensuring consistent operation over the long term.
