High-end incremental linear encoders – SV2 Series

Incremental linear encoder – SV2 series

Linear encoder with threaded head option for different installation options without the need for nuts.
Small mounting support that may be secured from the top or from the bottom for easier installation.

Especially indicated for high standard environments in terms of speed and vibration.
Their special design of the securing points of the linear encoder (TDMS™), drastically reduces the errors and ensures the accuracy and repeatability of the encoders.
