GM400.020A002 SSI Mutlak Enkoder Custom Replacement Solution

We offer a fully customized replacement solution for the GM400.020A002 encoder, designed to provide seamless compatibility with the original Baumer model. Our approach follows a 1:1 non-standard customization process, ensuring that the mechanical dimensions, electrical interfaces, and mounting features match the original precisely. With a production cycle of just 10–15 working days, our solution dramatically shortens delivery time compared to traditional overseas supply channels. This fast turnaround is particularly valuable for operators of wind turbines and industrial automation equipment, where minimizing downtime is critical for maintaining productivity and reducing maintenance costs. Our custom replacement not only guarantees reliable performance but also provides a cost-effective alternative to extended lead times from OEM suppliers, ensuring continuity in operations without compromising quality.

The GM400.020A002 replacement encoder is engineered for high-precision absolute position feedback under demanding conditions. As a multiturn SSI encoder using optical sensing technology, it delivers accurate singleturn resolution of up to 14 bits and multiturn resolution of 16 bits, meeting the stringent requirements of wind turbine pitch and yaw control, as well as industrial motion control systems. The encoder is designed with a clamping flange for robust mechanical installation, supports electronic zero-point adjustment for simplified commissioning, and includes a counting direction input for flexible integration. Optional incremental outputs are available, providing extended functionality for complex control architectures. Additionally, the encoder is built to withstand strong magnetic fields, ensuring stable and reliable operation even in environments with significant electromagnetic interference, such as nacelles, generator housings, or heavy-duty industrial machinery.
