ABSTRACT:
A non-contact magnetic potentiometer comprising a rotatably supported first yoke, a second yoke arranged as opposed to the first yoke at a slight spacing, a pair of permanent magnets fixed as inclined on the surface of the first yoke opposed to the second yoke and magnetized in the thickness direction, and a hall effect device fixed on the second yoke as opposed to the pair of permanent magnets, whereby the structure and manufacture can be simplified and an output voltage of any desired wave form can be obtained. This potentiometer is provided with a means for preventing the influences of the temperature and the variation with the lapse of years.
