Nidec Copal J Series Single-turn Wirewound Potentiometer

Nidec Copal J Series Single-turn Wirewound Potentiometer serves as a high-precision displacement sensor designed to convert mechanical movement into a proportional electrical voltage output through a robust resistor-and-wiper mechanism.

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.

Cement Type

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.
