The structure of rocker potentiometer sensor is explained in detail

　　1, solid potentiometer sensor: It is made of carbon black, graphite, quartz powder, organic adhesive and other materials mixed and heated, pressed on the plastic matrix, and then heated and polymerized.

　　Advantages: high resolution, good wear resistance, wide range of resistance values, high reliability, small size;

　　Disadvantages: loud noise, poor high temperature resistance.

　　Variety: Can be divided into small solid potentiometer sensor, linear solid potentiometer sensor, logarithmic solid potentiometer sensor.

　　Straight slide potentiometer sensor: the resistance body is rectangular bar shape, which changes the resistance value by linear movement of the slide handle connected with the slide seat.

　　2. Synthetic carbon film potentiometer sensor: It is the most used potentiometer sensor. The resistance body is made of a mixture of carbon black, graphite, quartz powder, organic adhesive, etc., which is coated on a rubber board or fiberglass board.

　　Advantages: high resolution, wide resistance range;

　　Disadvantages: large sliding noise, poor heat and moisture resistance.

　　Breed: There are ordinary synthetic carbon film potentiometer sensors, small synthetic carbon film potentiometer sensors with switches, single link switch (no switch) potentiometer sensors, double coaxial switchless (with switch) potentiometer sensors, double different axis switchless (with switch) potentiometer sensors, small precision synthetic carbon film potentiometer sensors, push open and close synthetic carbon film potentiometer sensors, straight slide synthesis Carbon film potentiometer sensor, precision multi-turn synthetic carbon film potentiometer sensor, etc.
