Model of Nidec Copal JC22E/JC22S Single-turn Conductive Plastic Potentiometer

Wirewound Type: 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.
Cement Type: The use of cermet resistors allows for low prices. The degradation is theoretically infinitely small. Cermet types are single-turn for use in servo drives and for settings.
Optical Contactless Type: The contactless configuration offers a much longer life and lower noise compared with the conventional contact method.
