The solid potentiometer is a kind of variable resistor. It is usually composed of a resistor and a rotating or sliding system, that is, a moving contact moves on the resistor to obtain a partial voltage output.
The resistor body of the solid potentiometer is mixed and heated with carbon black, quartz powder, organic binding powder and other materials, pressed into the plastic substrate, and then polymerized by heating.
It has the advantages of good wear resistance, high resolution, high reliability, wide resistance range and small size.
Adjust the size of voltage (including DC voltage and signal voltage) and current.
The resistor body of the potentiometer has two fixed ends. By manually adjusting the rotating shaft or slider to change the position of the moving contact on the resistor body, the resistance value between the moving contact and any fixed end is changed, thereby changing The magnitude of voltage and current.
Carbon black, quartz powder, organic binding powder
Solid potentiometers can be divided into small solid potentiometers, linear solid potentiometers, logarithmic solid potentiometers, etc. by type.
