GM400.012A102 SSI Codeur absolu Custom Replacement Solution

Our GM400.012A102 encoder replacement is designed as a 1:1 customized solution to ensure full compatibility with the original Baumer product. Through our non-standard production process, we replicate all critical mechanical and electrical specifications, providing a seamless replacement without requiring modifications to existing systems. With a typical production cycle of 10–15 working days, we can deliver these encoders quickly, allowing wind energy operators and industrial users to reduce downtime and maintain uninterrupted operation. This accelerated supply chain helps customers minimize maintenance delays and achieve higher operational efficiency, while also providing a dependable alternative to OEM components with longer delivery times.

The GM400.012A102 encoder features multiturn SSI absolute feedback with optical sensing, offering high-resolution position measurements suitable for wind turbines, industrial automation, and precision motion systems. Singleturn resolution reaches up to 14 bits, and multiturn resolution is 16 bits, ensuring accurate and reliable feedback in continuous-duty applications. The device is equipped with a clamping flange for stable installation, electronic zero-point adjustment for simplified setup, and counting direction input for flexible integration into control systems. Optional incremental outputs further expand its functionality. Designed with strong resistance to magnetic interference, the encoder performs reliably even in electrically noisy environments, making it suitable for turbine nacelles, generator housings, and industrial machinery where precision and durability are essential.
