The L18T Optical Linear Encoder is a compact and precise incremental encoder designed for reliable linear measurement. It keeps the core performance of the L18 series but includes a new housing fixation and improved thermal stability for more consistent operation.
It supports measuring lengths up to 1,240 mm and offers multiple grating periods and reference-mark configurations. With low moving force, IP64 protection (with compressed air), and solid vibration and shock resistance, the L18T performs well in demanding industrial applications.
