Carbon PCB Application scenarios

Carbon oil-printed PCB is a core contact resistive sensing component.

1. Game controllers: PS2, XBOX game controller joystick position detection

2. Automotive electronics: Windscreen wiper, car light, air conditioner rotary control sensors

3. Industrial electronics: Motor speed control modules, rotary potentiometers, angle position sensors

4. Home appliances: Fan, blender, oven rotary control knobs.

The arc carbon traces capture rotating movement and output an accurate resistance signal

for position & speed feedback.
