I'm doing a project that involves detecting rotary motion. One type of sensor I'm considering is a potentiometer which would be connected to a rotating disc. The problem I'm having is that all the potentiometers I can find are limited to 1 full revolution, whereas I need one that can tolerate an endless number of revolutions--like a radio dial.
The tough part is that is has to be very small. Smaller than these **broken link removed** ones if possible. I've tried Digikey, Newark, and local shops, but I can't find one that meets the size requirement--possibly because it goes by another name. Where can I find this kind of component?
Also, would "rotary potentiometer" be the proper name for such a device, or does it go by some other description?
