FSR402 FSR 402 Round Force Sensing Resistor
FSR 402 18.28 mm round force sensors from Interlink are robust polymer thick film (PTF) devices
Image of Interlink Electronics' FSR 402 Round Force Sensing ResistorInterlink 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 an 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 industrial and robotics applications.
The standard 402 sensor is around sensor 18.28 mm in diameter. Custom sensors can be manufactured in sizes ranging from 5 mm to over 600 mm. Female connector and short tail versions can also be ordered.
