40x40mm Thin Film FSR Pressure Sensor Force Sensitive Resistor Short tail 10G-20KG

A 40x40mm Thin Film FSR (Force Sensitive Resistor) Pressure Sensor with a Short Tail and a pressure range of 10 grams to 20 kilograms is a specialized electronic component used for detecting and measuring applied force or pressure.

Here’s a detailed description of its key characteristics:

• Size: The sensor has physical dimensions of 40x40mm, which means it has a square shape with sides measuring 40 millimeters each. This provides a relatively large sensing area for detecting pressure.
• Thin Film Technology: This FSR sensor utilizes thin film technology, which involves depositing a thin layer of resistive material onto a flexible substrate. When pressure is applied, the resistance of this thin film changes proportionally, allowing it to function as a force sensor.
• Pressure Sensing Range: The sensor is designed to detect and measure a wide range of pressures, spanning from a very light touch of 10 grams (0.01 kilograms) to a substantial force of 20 kilograms. This broad range makes it versatile for various applications.
• Short Tail: The “short tail” likely refers to the electrical connection or leads attached to the sensor. It might have short wires or connectors for interfacing with external circuitry.

Applications:

Thin film FSR pressure sensors find applications in various fields, including but not limited to:

• Human-Machine Interfaces: They can be integrated into touch-sensitive surfaces for user interfaces in devices like touchpads, touchscreens, and buttons.
• Medical Devices: Used in medical instruments and devices to measure pressure, for example, in force-sensitive foot pedals or pressure-sensitive mattresses for patients.
• Industrial Automation: Employed in manufacturing processes to monitor and control the application of force in machinery.
• Robotics: Integrated into robotic grippers and limbs to provide feedback on applied forces.
• Sports Equipment: Used in sports equipment such as pressure-sensitive mats for measuring impact forces or weightlifting platforms.
• Signal Conditioning: To use this FSR sensor effectively, you will typically need signal conditioning circuitry to convert the resistance changes into a usable electrical signal, such as voltage or current, that can be interpreted by a microcontroller or other electronics.
• Calibration: Depending on your specific application, you may need to calibrate the sensor to ensure accurate and consistent measurements across its pressure range.
