L50 optical modular linear encoder
The L50 Optical Modular Linear Encoder is a high-precision incremental linear encoder designed for accurate position measurement in industrial automation and precision machinery. Its modular design allows measuring lengths from 3,240 mm up to 30,040 mm, with a grating period of 40 µm and accuracy of ±10 µm per meter, making it ideal for long-travel applications.
The L50 encoder features programmable reference marks, high repeatability, and low required moving force, ensuring smooth, reliable operation. Its IP64 protection with compressed air, combined with robust vibration and shock resistance, allows it to perform in harsh industrial environments.
