FSR 406 Force Sensing Resistor – 38.1 mm Square

The FSR 406 Force Sensing Resistor is a thin, flexible pressure sensor designed to detect and measure applied force. With a square sensing area of 38.1 mm (1.5 inches), it is ideal for applications that require uniform pressure detection over a wider surface. As force increases, the sensor’s resistance decreases, enabling easy integration with microcontrollers and analog circuits.

Built for reliability and ease of use, the FSR 406 is commonly used in robotics, IoT projects, human–machine interfaces, industrial automation, medical devices, and educational prototyping. Its lightweight, low-profile design allows it to be embedded in tight spaces without affecting performance.
