Force-Sensing Resistor: 1.5cm-Diameter Circle, Short Tail FSR 402 ShortInterlink
This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.58″-diameter (1.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimized for use in human touch control applications.
