The Avago HEDR-5xxx Series encoders are high performance replacements for our existing low cost HEDS-5xxx series three channel optical encoders. These upgraded encoders now come with higher resolution ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

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 ...
