GM400.Z54 SSI Codeur absolu Custom Replacement Solution
Our customized replacement solution for the GM400.Z54 encoder offers a practical and reliable alternative for Baumer users. We deliver products through a 1:1 non-standard customization method, ensuring exact mechanical fit and full electrical compatibility. With a rapid production cycle of only 10–15 working days, customers benefit from shorter waiting periods, which is essential for wind energy projects where maintenance speed and supply reliability are critical factors.
The GM400.Z54 replacement encoder is designed for absolute position measurement under challenging conditions. Utilizing an optical sensing principle, it provides high precision and long-term stability. The encoder achieves resolutions of up to 14-bit per revolution in singleturn mode and 16-bit in multiturn mode, suitable for wind turbine pitch control and yaw feedback systems. It is equipped with a clamping flange, enabling stable installation, and allows for electronic zero-point adjustment to simplify calibration. Additional functions include counting direction input and optional incremental outputs, while its construction ensures excellent resistance to strong magnetic fields, maintaining accuracy even in environments with significant electromagnetic noise.
