    Tips: How to choose an incremental optical linear encoder?

    • Resolution: Choose the resolution (e.g., 0.1 µm, 0.5 µm, 1 µm) based on your required precision.
    • Signal Output: Decide between digital (e.g., AB quadrature) or analog signals based on your system’s needs.
    • Installation and Size: Ensure the encoder fits your mounting requirements.
    • Environmental Conditions: Select one that can operate reliably in your environment (e.g., temperature, humidity).
    • Additional Features: Consider features like built-in reference points or robust shielding for interference resistance.
    • Cost vs Performance: Balance your budget with the required performance specifications.
