Force Sensor

The model 402 FSR is a single-zone Force Sensing Resistor optimized for use in human touch control of electronic devices such as automotive electronics, medical systems, and in industrial and robotics applications. FSRs are two-wire devices. They are robust polymer thick film (PTF) sensors that exhibit a decrease in resistance with increase in force applied to the surface of the sensor. It has a 14.7mm diameter active area and is available in 4 connection options. Interlink Electronics FSR 400 series is part of the single zone Force Sensing Resistor family.

Product Description


You can buy this force sensor at great ratings and price from amazon by clicking here and if available, you can buy it from ebay in much cheaper price then amazon by clicking here.


You can view or download the datasheet of FSR(Force Sensitive Resistor) from here.


As this is one kind of resistor which is in other words a passive device, doesn’t have any particular pin diagram.The resistance between both the ends of FSR will vary according to the pressure applied.


This video will let you know how this FSR works an also let you know how to use it with one simple project.
