How It Works: Optical Rotary Encoder Technology

Optical rotary encoders work by shining an LED light through a precision code disk that’s attached to the rotating shaft. Photodetectors on the other side pick up the light patterns, translating them into electrical signals representing position and movement. This optical encoding principle delivers high accuracy and repeatability.

There are two main configurations: transmissive and reflective. In the transmissive setup, the light passes through the code disk’s transparent and opaque sections. In the reflective type, the LED shines light onto a patterned surface, and the reflected light is detected. Both types offer distinct advantages depending on your application needs.

Our optical rotary encoders come in incremental and absolute output versions. Incremental encoders generate A/B quadrature signals plus an index pulse to track relative position changes, ideal for motion control that resets or tracks movements dynamically. Absolute encoders provide a unique position code for every shaft angle, perfect when precise, non-volatile positioning is required.

Compared to magnetic encoders, optical rotary encoders offer higher resolution and better immunity to electromagnetic interference (EMI), making them well-suited for precision tasks in clean and controlled environments. This makes them a reliable choice for demanding applications that require precise position feedback and consistent performance.Explore related solutions like our optical incremental shaft encoder to see how these technologies deliver efficiency and accuracy in real-world setups.
