Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

Rotary encoders are critical to many applications, even at the hobbyist level. While considering his own rotary encoding needs for upcoming projects, it occurred to [Jan Mrázek] to try making his own ...

This is an incremental rotary encoder that uses contactless magnetic sensing to detect rotational speed and direction. The two Hall Effect sensors measure the 66-pole ring magnet and output two ...

As per its creator, the AEAT-6600-T16 debuts as the industry’s highest-resolution Hall-Effect magnetic encoder. The component targets industrial applications, particularly those in harsh environments.
