The key components of potentiometer are resistance body and brush. According to the structural form between both and whether to contain switch, potentiometer can be divided into a few kinds of types. Potentiometer still can press the material classification of resistance body, if line is wound, synthetic carbon film, metallic glass glaze, organic solid core and conductive plastic wait for type, electric property basically decides at the material that uses. In addition, there are metal foil, metal film and metal oxide film made of resistor potentiometers, with special purposes. Potentiometer according to the characteristics of use, there are general, high precision, high resolution, high resistance, high temperature, high frequency, high power potentiometer; According to the resistance value regulation method, there are adjustable, half adjustable and fine tuning, after the two also called half fixed potentiometer. To overcome the brush on resistance body mobile contact to potentiometer performance and life to bring adverse impact, there is no contact non-contact type potentiometer, such as photosensitive and magnetic sensitive potentiometer, for a few special application.
