FSR402 Force Sensitive Resistor – Pressure Sensor 0.2–20N

The FSR402 Force Sensitive Resistor detects physical pressure, squeezing, and weight, outputting a variable resistance based on the applied force. With its thin, flexible design, it’s ideal for robotics, wearable electronics, musical instruments, and interactive projects.

• Sensing range: 0.2N to 20N (approx. 0.02kg to 2kg)

• Shape: Round sensing area (~12mm diameter)

• Thickness: ~0.5mm flexible polymer film

• Output: Resistance decreases as force increases

• Operating voltage: 0–5V (compatible with Arduino, Raspberry Pi, ESP32, etc.)

• Applications: Touch detection, grip sensing, robotics feedback, pressure mapping
  Lightweight, durable, and easy to integrate into any pressure-sensitive interface.
