FSR03DE

FSR03DE is a FSR series force sensing resistor. It exhibits the unique characteristic of dynamic resistance related to the amount of applied force. When more force applied to the surface of the sensor, it lowers the resistance. The resistance change is inversely proportional to the applied force. This force-sensing resistor is characterized for Human machine interface (HMI) or Machine-machine interface (MMI) applications. Specific device characteristics will depend on the size, shape and materials used in construction. Force-sensing resistors are intended for applications where a delta in applied force is to be detected. They are not intended for high accuracy or specific weight measurement applications.
