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 ...

Get the most out of brushless dc motors by specifying optical encoders. They measure finer movements than hall sensors, because their operation doesn't rely on motor phases. Brushless dc (BLDC) motors ...

While standard optical encoders have traditionally been used to meet the needs of high-precision sensing and control applications (such as steering-wheel position detection or industrial motion ...

The AEDR 8400 series are the industry’s smallest reflective incremental optical encoders, according to Avago Technologies. The encoders combine this extremely small size—3.00 mm by 3.28 mm by 1.262 mm ...

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 ...

Continuing his tradition of making bits of wire and scraps of wood work wonders, [HomoFaciens] is back with a unique and clever design for an electromechanical encoder. There are lots of ways to build ...
