HSFPAR003A

The key features of the force sensor described in the document include: 1. The sensor should not be subjected to a static force or impact force of 50N or more. 2. Force should not be applied at an angle to the sensor. 3. The sensor should be protected from dust such as sand and substances that corrode solder. 4. The recommended material for the sensor is SUS404C with a thickness of 0.2mm. 5. The sensor is designed to detect the load force of a pen tip in the opposite direction, limiting the impact stress on the sensor projection. 6. A coil spring is recommended to limit displacement and impact force on the sensor. 7. The force applied to the sensor should be limited to F < 8 8. A stainless steel metal plate, specifically SUS404C, is recommended for the sensor. 9. The sensor output changes based on the load force applied. 10. The sensor operates based on the strain of a diaphragm by external force, changing the resistance of the Piezo element and outputting an analog voltage in response to force changes.

The product number of the document is HSFPAR003A.

The force sensor described in the document utilizes the piezo resistive effect by having a piezo resistive bridge circuit formed on a silicon diaphragm. When a force is applied to the diaphragm, it causes the diaphragm to flex, generating stress on the piezo resistors, which in turn changes their resistance .
