The Interlink Force Sensing Resistor uses a 0.2” (5mm) circular pad to sense applied force.

Force Sensing Resistors (FSRs) are very thin, robust, polymer thick film (PTF) devices that decrease in resistance when increased pressure is applied to the surface of the sensor.

FSRs are not a load cell or strain gauge devices though they have many similar properties. They are more appropriate for qualitative rather than precision measurements.

It can be used to provide a 0-5vdc output that is proportional to the amount of force applied. Includes one FSR and one rubber bumper.
