TK90

TK910 – TK911 – TK920 – TK921

Optical incremental encoder – Solid shaft

Robust incremental optical encoder suitable for different industrial applications, especially in harsh environments.
Thanks to its robust construction and high protection degree this model allows to operate in harsh environments where
challenging ambient conditions such as dust, liquids, temperature, shocks and vibrations are available, ensuring high
reliability and long service life.
