Interlink's FSR 402 is a thin polymer film whose resistance collapses as you press it - over 10 megohms untouched, down to about 1 kilohm at full force - so one resistor and an analog pin tell you how hard it is being pressed. It responds from about 0.2 N to 20 N across a 12.7 mm round active area on a 0.46 mm flexible tail. A good 'how hard' sensor rather than a calibrated scale.
Key features
- Resistance drops from over 10 megohms to about 1 kilohm
- Force range about 0.2 N to 20 N
- 12.7 mm round active area, 0.46 mm thin and flexible
- Rated for up to 10 million actuations
- Passive - just add one resistor for a voltage divider
- For touch pads, grip sensing and pressure-triggered projects
