GM400.Z21 SSI Absolute Encoder Custom Replacement Solution
For the GM400.Z21 encoder, we provide a customized replacement solution based on precise 1:1 non-standard customization. This approach guarantees that the replacement product maintains the same performance and interface characteristics as the original Baumer encoder. With a fast manufacturing cycle of 10–15 working days, our service shortens the supply chain and provides users with quick access to reliable components, reducing turbine downtime and increasing operational efficiency.
The GM400.Z21 replacement encoder offers multiturn absolute measurement through SSI communication, using optical scanning for dependable accuracy. With singleturn resolution up to 14 bits and multiturn resolution up to 16 bits, the encoder ensures precise position data transmission. Designed with a clamping flange, it installs securely and withstands mechanical stress. Functions such as electronic zero-point setting and direction input support flexible integration into different control architectures. Its strong resistance against magnetic fields makes it suitable for high-interference industrial environments, especially in wind turbine nacelles where electrical noise is common.
