Description

The SOUSHINE FSR412 is a piezoresistive force-sensing resistor that changes its electrical resistance in response to applied force or pressure. Its construction utilizes a conductive polymer film that exhibits a decrease in resistance as force increases, providing an analog voltage output when used in a simple voltage divider circuit. This principle allows for direct interfacing with analog-to-digital converters on most microcontrollers.

Engineered for reliability, the sensor operates across an industrial temperature range of -20°C to 60°C and features inherent immunity to electromagnetic interference (EMI) and electrostatic discharge (ESD). Its robust design ensures signal stability and repeatable measurements, making it suitable for embedded systems requiring consistent force feedback.

Key Features

  • 3mm active sensing area with a minimal 0.325mm thickness for low-profile designs.
  • Precise force detection with a low activation threshold of 30g and a maximum range of 10kg.
  • Exceptional mechanical lifespan exceeding 1 million compression cycles.
  • Rapid dynamic response with sub-1ms reaction time and under 15ms recovery.
  • High initial impedance of 10MΩ for low-power circuit designs.
  • Wide operating temperature from -20°C to 60°C for varied environments.
  • Built-in resistance to EMI and ESD for enhanced signal integrity in noisy conditions.
  • Optimized performance-to-cost ratio for high-volume integration.

Applications

  • Robotic gripper and end-effector tactile feedback systems.
  • Medical device pressure monitoring and patient interface sensing.
  • Industrial process control for lightweight part presence detection.
  • Consumer electronics for button replacement and intuitive touch interfaces.
  • Wearable technology for activity monitoring and gesture recognition.

Frequently Asked Questions

What is the operating voltage for the FSR412 sensor?

The FSR412 is designed to operate with a test voltage between 3V and 5V DC. This range makes it directly compatible with common 3.3V and 5V logic systems found on Arduino, Raspberry Pi, and other microcontrollers without requiring additional signal conditioning.

How do I interface the FSR412 with a microcontroller?

Interface the FSR412 by creating a simple voltage divider circuit. Connect one sensor lead to your microcontroller's voltage supply (3-5V) and the other lead to a pull-down resistor (typically 10kΩ to 100kΩ) tied to ground. The junction between the sensor and the resistor provides an analog voltage signal that can be read by an ADC pin.

What is the minimum detectable force (threshold) for this sensor?

The sensor has a specified response point of 30 grams. This means it will begin to show a measurable change in resistance when a force as low as 30g is applied, providing high sensitivity for detecting very light touches or pressures.

Is the FSR412 suitable for high-cycle applications?

Yes, the FSR412 is rated for a mechanical durability of over 1 million actuation cycles. Its robust thin-film construction ensures long-term reliability in applications requiring repeated force detection, such as buttons, switches, or continuous monitoring systems.
