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 ...

Noncontact magnetic rotary encoders are hard to beat when it comes to measuring rotary motion in machinery, as they are relatively small, strong, and inexpensive devices compared to traditional ...

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

SICK has unveiled its next-generation family of large-bore hollow-shaft incremental encoders, the SICK DGS80. An innovative design concept has opened up versatileintegration possibilities for the ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

It’s easy to treat optical encoders as “black boxes” that need minimal consideration before they are installed to translate rotary motion into position or velocity feedback signals for a motion ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Incremental-rotation or linear encoders are very common, but normally they do not provide a direction signal. This design shows an easy way to detect forward or reverse direction. Incremental encoders ...
