The optical rotary encoder consists of a precision circular optical scale and a compact readhead, providing high-resolution position feedback for demanding motion control applications.
The compact readhead features a built-in LED indicator for easy installation and setup. It provides digital output resolution up to 32 nm, while the integrated index detector simplifies system integration and enhances positioning reliability.
Non-contact Design: Utilizes a non-contact optical sensing principle to eliminate mechanical wear, ensuring long-term stability and durability.
High-resolution Output: Offers digital output resolution up to 32 nm, enabling ultra-precise positioning and measurement.
Compact Readhead with Built-in LED Indicator: The compact readhead features an integrated LED for easy installation and alignment verification.
