Nidec Copal JC30S/JC40S Single-turn Wirewound PotentiometerIndonesia Industrial Parts

Description

Nidec Copal JC30S/JC40S potentiometers are essentially displacement sensors. They work by converting mechanical movement into an electrical signal (voltage). This happens through a simple mechanism: a resistor and a moving contact (wiper). As the resistor moves relative to the wiper, the resulting voltage output precisely reflects the amount of movement.

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.
