This 100mm SoftPot membrane potentiometer is a very thin variable potentiometer. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculates the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

To use Connect one side pin to ground via a 10K resistor in series. Connect the other side pin to your Vcc power line (3V, 5V etc) via a different 10K resistor in series. Then read the analogue voltage on the centre pin. It will range from 1/3 Vcc to 2/3 Vcc.

Please Note:

  • Do not connect to Ground and Power directly!
