L35
The L35 Optical Linear Encoder delivers high-precision incremental linear measurement for reliable and vibration-resistant position feedback. It supports measuring lengths up to 3,240 mm and achieves accuracy up to ±3 µm per meter, depending on the selected module length. The L35 series offers enhanced vibration resistance compared to the L18 series, making it ideal for precision motion control applications.
Its modular reference mark options, low required moving force, and IP64 protection with compressed air ensure consistent, robust performance in demanding industrial environments.
