The FSR 402 is a single-zone force-sensing resistor with a 0.5-inch circular active sensing area that decreases in resistance as physical pressure increases.
Key Specifications
- Force Range: 0.2 N to 20 N (approx. 100 g to 10 kg)
- No-Pressure Resistance: Greater than 1 MΩ
- Full-Pressure Resistance: Down to ~1.8 kΩ
- Durability: Over 10 million actuations
- Operating Temperature: -30°C to +70°C (or up to +85°C depending on build)
Common Applications
- Robotics: Sensing grip pressure on robot fingers or ground contact on feet
- Interface Design: Touch-sensitive pads and custom musical/MIDI controllers
- Consumer Electronics: Pressure-activated switches and wearable measurement devices
