Force-Sensing Resistor: 0.5cm-Diameter Circle, Short Tail FSR 400 Short

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.25-diameter (0.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimized for use in human touch control applications.

We have seven versions of force-sensing resistors available, which lets you choose the one with the dimensions that best suit your application:

• 0.5cm-diameter circle (FSR 400)
• 0.5cm-diameter circle, short tail (FSR 400 Short)
• 1.5cm-diameter circle (FSR 402)
• 1.5cm-diameter circle, short tail (FSR 402 Short)
• 4cm x 4cm square (FSR 406)
• 3.6cm x 1.0cm strip (standard FSLP)
• 10cm x 1cm strip (10 cm FSLP)
