As the disk rotates, these patterns interrupt the light emitted onto the photodetector, generating a digital square-pulse output. 1. In an optical encoder (left), a pair of light-source/reflector ...

A fairly common method for electronic interpolation is to use a voltage divider circuit ... with a magnetic pulse wheel that shares many characteristics with the encoders based on this technology ...

In encoders with Wiegand-based coils that count multiple revolutions, this change in magnetic polarity generates a current pulse in a copper coil wrapped around the Wiegand wire. As the external ...

Sponsored by Digi-Key and CUI Inc.: Optical and magnetic encoders dominate the market, but the capacitive electric encoder is pushing its way into the mix with enhanced resolution, ruggedness ...
