The FSR402 Force Sensitive Resistor is a lightweight, ultra-thin pressure sensor that precisely detects forces from 100 grams up to 10 kilograms. Designed for intuitive integration with Arduino, UNO R3, and other microcontrollers, this sensor changes its electrical resistance depending on the pressure applied. The stronger the force, the lower the resistance—making it ideal for various smart sensing and interactive applications.
Built for durability with a lifetime of more than 10 million actuations, the FSR402 provides consistent and accurate performance. Its compact 0.5-inch circular sensing area ensures easy installation in robotics, medical devices, and touch-based interfaces.
