The FSR 400 model is a single zone forced sensing resistor ®， Optimized for human touch control of electronic devices such as automotive electronics, medical systems, and industrial and robotic applications. FSR is a dual line device. They are robust polymer thick film (PTF) sensors that exhibit a decrease in resistance as the force applied to the sensor surface increases. It has an effective area with a diameter of 5.1mm and 4 connection options. The Interlink Electronics FSR 400 series is part of the single zone force sensing resistor series.
