FSR® 400 Series

Interlink Electronics FSR™ 400 series is part of the single zone Force Sensing Resistor™ family.

Force Sensing Resistors, or FSRs, are robust polymer thick film (PTF) devices that exhibit a decrease in resistance with increase in force applied to the surface of the sensor.

This force sensitivity is optimized for use in human touch control of electronic devices such as automotive, electronics, medical systems, and in industrial and robotics applications.
