I am trying to find a component, that, similar to a potentiometer, delivers an analog output, but which can be turned indefinitely in a single direction.
I have tried searching for something like this, but I never quite found anything that does what I want, while being relatively cheap.
Please note, that I am not searching for a rotary encoder, since they either are clicky, do not have the resolution I require, do not support absolute positioning and are usually too expensive if they do support any of these.
I imagine something like a normal potentiometer with multiple wiper contacts might work in this case.
It would provide a smooth precise output even when turned in a single direction for multiple turns.
Does a cheap part exist that behaves like this and if so what is it called?
Edit: thanks /u/quetzalcoatl for providing the output potential diagram.
