This is a very thin variable potentiometer. By pressing down on various parts of the strip, the resistance linearly changes from 100Ω to 10,000Ω allowing you to very calculate the relative position on the strip accurately. It can be used as a positional indicator for CNC head positioning, variable user input (e.g. volume level input), straight user input (multiple button areas translate to given resistance levels), and many other applications.
The SoftPot comes with adhesive backing. Its connector is 0.1" spaced and breadboard friendly. This version has a 500mm active area.
