Square Force Sensor Resistor FSR with 39.1mm Force Sensing

“Precision Force Sensing with 39.1mm Square Force Sensor Resistor”

SKU : RW-1149

A force sensor resistor (FSR) that is 39.1mm square is a specific type of sensor designed to measure force or pressure. Here’s a description of such a sensor:

1. Size and Shape: The Force sensor is a square shape with sides measuring 39.1mm (millimeters) in length. This square shape makes it suitable for measuring force or pressure over a relatively large area.
2. Construction: Typically, FSRs consist of a thin, flexible, and flat material with conductive particles embedded in it. When a force is applied to the sensor, the resistance of the material changes. This change in resistance is used to measure the magnitude of the applied force.
3. Measurement Range: The sensor’s sensitivity or measurement range would depend on its design and specifications. Different FSRs are available with varying measurement ranges, so you would need to refer to the manufacturer’s specifications for the specific sensor to know its range.
4. Applications: FSRs have a wide range of applications, including but not limited to:
   • Human touch detection in devices like touchscreens, interactive displays, and electronic musical instruments.
   • Force-sensitive input for robotics and automation.
   • Monitoring seat occupancy in vehicles for airbag deployment.
   • Medical devices for measuring pressure and force in biomedical applications.
5. Output: The output of an FSR is typically an analog signal, and the magnitude of the force applied can be determined based on the change in resistance. Some FSRs may require signal conditioning or amplification to make their output suitable for measurement and control systems.
6. Installation: These sensors can be integrated into various systems by adhering them to a surface or embedding them in a housing designed for the specific application. They are often used in combination with a microcontroller or data acquisition system to convert the resistance changes into meaningful force measurements.
7. Accuracy: The accuracy and repeatability of the measurements will depend on the quality and calibration of the specific FSR and the conditions under which it is used.

Remember that the specific specifications and characteristics of a 39.1mm square FSR may vary depending on the manufacturer and model, so it’s essential to refer to the product documentation or datasheet provided by the manufacturer for detailed information on its performance and usage.
