FSR 400 Series Data Sheet Force Sensing Resistors Features and Benefits Description Actuation Force as los w as 0.2N and sensitivity range to 20N 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 Cost Effective (PTF) devices that exhibit a decrease in resistance with increase in force applied to Ultra Thin the surface of the sensor. This force sensitivity is optimized for use in human touch Robust up to 10M actuations control of electronics devices such as automotive electronics, medical systems, Simple and easy to integrate iinndduussttrriiaall,, aanndd rroobboottiiccss aapppplliiccaattiioonnss.. The 400 series sensors come in six different models with four different connecting options.
