Hi,
Hi, I search a rotational potentiometer to connect it in a DC motor for know the angle (I purposely don't want a servo)
Does anyone know if there are a potentiometer without limitation ?
I see a lot of potentiometer that have until 10 rotation limitation but my question is if there are exist a non rotation potentiometer limitation ?
They do exist (there's two on the table right in front of me), but they're usually only made for special uses, so they're not exactly cheap.
Regular potentiometers can be found which can be modified if you're handy, but all potentiometer based encoders will go from a few Ohm to max. and then repeat of course.
Then there's angular encoders of various construction, switches, gated infrared light, hall based etc. For the critical stuff, some people still use resolvers (devices that outputs a sine and a cosine signal).
If you tell us what it's for, the needed precision, estimated lifetime etc. and your budget, I'm sure a solution can be found.
