I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

A while back we featured a magnetic rotary encoder that [LongHairedHacker] designed. The heart of the system is an AS5043 magnetic rotary sensor which runs from $6.5-$11 and has a 10 bits precision… ...

Long-life manual rotary encoder EBE Sensors+Motion has revised its manual handwheel rotary encoder, designed for precise adjustment of machines. Inside the encoder, called HR100, the 100 detent ...

Similar in size and shape to the common panel-mounted potentiometer, the incremental rotary encoder provides an inexpensive ‘digital’ alternative to the analog potentiometer. It is typically used to ...

Encoders are prominent in the medical industry because of the precision necessary to accurately and safely test and treat the human body—and develop new procedures in the lab.

Once you have a suitable donor mouse with a rotary encoder, you will gut the mouse removing the scroll wheel, rotary encoder, cord, and circuit board.

The SMA3 bearingless absolute encoder can be installed in rotary and linear applications and integrates the Multipole Pitch Technology. It is designed for linear measuring lengths up to 19.3 m (63 ...
