1/2" Circular Force Sensing Resistor

This force-sensing resistor (FSR) is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the circular active area (0.5"/12.7mm diameter), allowing you to create a sensor that is able to detect force or pressure. The polymer thick film (PFT) device is optimized for use in human touch control of electronic devices and can sense an applied force ranging from a few dozen grams to over 10 kg (22 lb).


  • Diameter: 0.5" (12.7 mm)
  • Length of flexible leads: 1.4" (35.56mm)
  • Lowest amount of force measurable: 50 grams


  • Pressure-sensitive touch user interface
  • Tactile sensor for robotic appendages
  • Finger pads for special gloves
  • Target contact detection
