L37
The L37 Optical Linear Encoder is a high-precision incremental linear encoder designed for reliable position measurement in compact and industrial automation systems. Its reversible reading head and reproducible thermal behavior ensure consistent, accurate feedback.
The L37 supports measuring lengths up to 3,240 mm, with accuracy grades up to ±3 µm per meter, making it ideal for precise motion control applications. Its modular reference mark options, low moving force, and IP64 protection with compressed air provide robust performance in harsh environments.
