Force Sensing Resistor (FSR)

FRX1T

The FRX1T is a miniature single-zone force-sensitive resistor (FSR) with a 5mm diameter sensing area and a 13mm x 7mm form factor. Its compact design supports single-point force detection, offering flexibility for integration in space-constrained environments and a wide range of pressure-sensing applications.
