Nidec Copal J Series Single-turn Wirewound 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 voltage output. A voltage is applied to both ends of the resistor, and the wiper is moved.
Model of potentiometer
Precision wire winding technology has been used to achieve low noise and long life. Wirewound types include the single-turn J series for use in servo drives and the multiturn M series for use in settings.
Conductive Plastic Type
Special film resistors and original contact construction provide long life, with degradation that is theoretically infinitely small. Conductive plastic types include single-turn types and linear types, both for use in servo drives.
The use of cermet resistors allows for a low price. The degradation is theoretically infinitely small. Cermet types are single-turn for use in servo drives and for settings.
