Force Sensing Resistors®
Description
Interlink Electronics FSR® 400 Series is part of the single zone Force Sensing Resistor®
family. Force Sensing Resistors, or FSR's, 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 machine interface devices
including automotive electronics, medical systems, industrial controls and robotics.
The FSR 400 Series sensors come in seven different models with four different connecting
options. A battery operated demo is available. Call us for more information at

Connector Information
Application Information
For specific application needs please contact Interlink Electronics support team.
An Integration Guide and Hardware Development Kit (HDK) are also available.
FSR's are two-wire devices with a resistance that depends on applied
force. Below is a force vs. resistance graph that illustrates a typical FSR®
response characteristic. Please note that the graph values are reference only
and actual values are dependent upon actuation system mechanics and
sensor geometry.
For simple force-to-voltage conversion, the FSR device is tied to a measuring
resistor in a voltage divider (see figure below) and the output is described by the
following equation.
Force Sensing Resistor®
FSR® 400 Series Data Sheet
In the configuration shown, the output voltage increases with increasing force. If RFSR
and RM are swapped, the output swing will decrease with increasing force. The
measuring resistor, RM, is chosen to maximize the desired force sensitivity range and
to limit current. Depending on the impedance requirements of the measuring circuit,
the voltage divider could be followed by an op-amp.
A family of force vs. VOUT curves is shown on the graph below for a standard FSR in a
voltage divider configuration with various RM resistors. A V+ of 5V was used for these
examples. Please note that the graph values are for reference only and will vary between
different sensors and applications.
Refer to the FSR Integration Guide for more integration methods and techniques.
