Description

The SOUSHINE FSR400 is a force-sensing resistor based on polymer thick film (PTF) technology. When force is applied to its 5.6mm active area, the conductive particles within the polymer film move closer together, causing a predictable decrease in electrical resistance. This analog resistance change can be easily measured using a simple voltage divider circuit connected to an ADC input on a microcontroller.

Designed for durability, the sensor’s robust construction withstands millions of actuations, making it suitable for long-term use in interactive controls. Its ultra-thin profile and flexible tail allow for integration into space-constrained applications where discrete force detection is required, from consumer electronics to industrial control panels.

Key Features

  • Force-Sensitive Resistor: Provides analog resistance output inversely proportional to the applied force.
  • Wide Dynamic Range: Sensitive to forces from as low as 0.1N (~10g) up to 100N (~10kg).
  • High Durability: Engineered for long life with a rating of up to 10 million actuations.
  • Ultra-Thin Form Factor: Minimal profile ideal for integration into slim devices and assemblies.
  • Simple Two-Wire Interface: Easy to connect and read using a basic voltage divider circuit.
  • Polymer Thick Film Construction: Offers a robust and cost-effective sensing solution.

Applications

  • Touch-sensitive control panels and buttons in automotive interiors.
  • Medical device input systems for bed controls or instrument activation.
  • Robotic gripper and end-effector tactile feedback systems.
  • Interactive consumer electronics, gaming controllers, and musical instruments.
  • Industrial human-machine interface (HMI) panels requiring durable, sealed controls.

Frequently Asked Questions

How do I connect and read the FSR400 sensor with an Arduino?

Connect one FSR wire to 5V and the other to an analog pin (A0) via a 10kΩ pull-down resistor to GND. The voltage at the analog pin will vary with the applied force. Use the Arduino's analogRead() function to measure this voltage, which correlates to the sensor's resistance and thus the force.

What is the electrical interface for the FSR400?

The FSR400 is a simple two-wire resistive device. Its resistance decreases non-linearly as force increases. It requires an external circuit, typically a voltage divider, to convert the resistance change into a measurable voltage for a microcontroller's ADC input.

What is the minimum and maximum detectable force for this sensor?

The FSR400 is sensitive to forces as low as approximately 0.1 Newtons (about 30 grams) and can measure up to around 100 Newtons (10 kilograms). The response is non-linear, with higher sensitivity at lower force ranges.

Is the FSR400 suitable for high-cycle, durable applications?

Yes, the sensor is constructed with robust polymer thick film technology and is rated for up to 10 million actuations, making it suitable for long-term use in interactive controls, industrial panels, and robotic tactile systems.
