POT-W10L333 is a resistive long-strip type film position sensor.
The PIN3 of the sensor is grounded, PIN1 is connected to the power voltage V+, and PIN2 is the output voltage of the sensor. When no voltage is applied to the sensing area, PIN2 is in an open state and the output voltage V1 is 0; when there is pressure (20g – 50g), the sensor is triggered, and V1 outputs a voltage signal. As the pressure application position moves from the right end of the sensor to the left end, V1 increases, and the change range is from 0V+ to V+ in a linear manner. The voltage value of V1 is determined by the pressure application position; after the pressure is removed, the sensor returns to the disconnected state, and the voltage of V1 is 0.
