What is the cause of bad synchronization of adjustable potentiometer?

What is the cause of bad synchronization of adjustable potentiometer?

1. Poor design of the potentiometer carbon sheet or improper process control (such as Angle design of the edge of each transition layer and proportional control of resistance value);

2. The connection between the inner and outer contact bubble points of the brush is not on the same line or through the center point of the brush;

3. Excessive or insufficient brush compression (such as the improper matching height of R121G series housing and shaft may lead to excessive or insufficient brush compression);

4. Adhesive on the terminal leads to poor contact between the terminal and the probe of the detection fixture;

5. Carbon chip cracking or terminal loosening cause no output on one side;

6. The brush track completely slides out of the carbon plate printing pattern at a certain point;

7. The brush disconnects from the contact with the carbon sheet at a certain point due to the foreign body attached to the surface of the carbon sheet;

8. The deformation of the potentiometer brush results in poor contact with the carbon sheet;

9. For R161G series products, improper assembly of the up-moving piece (such as uneven or not in place) may lead to poor synchronization. http://www.abf.wang
