High-end incremental linear encoders – SV Series

Incremental linear encoder – SV series

Specially designed for high performance environment requiring high speed and accuracy and the need to withstand higher vibrations.

The TDMS™ mounting system incorporated through a separate back bar ensures greater accuracy, higher repeatability and ability to withstand vibrations without compromising machine performance.
