My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
