Description Of Nidec Copal JP-30 Single-turn Cement 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.

Nidec Copal JP-30 Single-turn Cerment Potentiometer

A voltage is applied to both ends of the resistor, and the wiper is moved. The displacement is measured by the voltage between one terminal of the resistor and the wiper. Looking at the component structurally, we can see the following: (Fig. 1) Further, the following formulas apply to the voltage output

Model of 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

Contactless configuration offers a much longer life and lower noise compared with the conventional contact method.

Perform soldering of the terminals at 380 °C for no more three seconds, and avoid applying excess heat. Also, avoid applying outside force to the terminals.
In case of using multiturn potentiometers, when rotating the shaft to the mechanical limit, apply torque below the strength of the stopper. Also, give due consideration to thrust and radial loading.
