After a slight purchasing mishap, I am to end up with an encoder whose max RPM is too low for the application for which it is to be used. To achieve roughly the same purpose (that is, sensing of an angle) with a lower budget, we are now looking to use a potentiometer. Just to make sure that we don't make the same mistake again, is there a maximum speed which potentiometers can generally be turned? Say, something faster than the 60 RPM max we found out about on the purchased parts? I've looked through the data sheets for a couple different potentiometers, but I can't seem to find anything (though I suppose that makes sense since these potentiometers are fixed rotation).
Any advice is appreciated.
