Nidec Copal JC10 Single-turn Conductive Plastic Potentiometer

Nidec Copal JC10 is a high-precision, single-turn conductive plastic potentiometer engineered to function as a linear shift sensor by translating mechanical displacement into an accurate analog voltage signal.

Model of a 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.

Cerment 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.
