Re: Walking Encoder Values

To measure the arm position, I prefer an absolute angular position sensor. Such as a potentiometer. There are some problems with pots since they are a mechanical device. We prefer to use magnetic absolute encoders. Last year we used a Cherry AN8 series 360 non-contact absolute encoder. This year we are using Vishay 981HE encoders for our pivot modules and arm. They give an analog voltage output from .5 to 4.5 volts 0-360 degrees. Both of these devices are rugged and automotive qualified.
