Nidec Copal JP-30B Single-turn Cement Potentiometer Nidec Copal JP-30B Single-turn Cerment Potentiometer Potentiometers are displacement sensors that produce electrical output (voltage) in proportion to the mechanical displacement. They are basically composed of a resistor and a wiper (brush), with the mechanical displacement of the resistor relative to the wiper being accurately converted into an electrical […]
