Description

The SOUSHINE FSR402 operates on the principle of piezoresistivity, where applied force decreases the internal resistance of a specialized polymer thick film. This change in resistance provides an analog signal proportional to the applied pressure, enabling precise measurement across its 20g to 10Kg range.

Constructed from durable PET film, the sensor offers mechanical flexibility and long-term reliability. The IP65-rated sealing protects the sensing element from dust ingress and low-pressure water jets, making it suitable for applications exposed to challenging environments. Its simple two-wire interface (long tail leads) facilitates easy integration with microcontroller ADCs, op-amp conditioning circuits, or dedicated FSR interface ICs for accurate signal acquisition.

Key Features

  • Piezoresistive force-sensing element for analog resistance output proportional to applied load.
  • Flexible and thin form factor using robust PET material for durable, conformal installations.
  • IP65 protection rating for reliable performance in dusty or damp operating conditions.
  • Wide dynamic range capable of detecting forces from delicate touch (20g) to significant loads (10kg).
  • Compact 14.7mm circular active area ideal for embedded tactile interfaces and pressure mapping arrays.
  • Simple two-terminal interface with long flexible leads for straightforward soldering and wiring.
  • High repeatability and stability for consistent measurements in user interface and control applications.
  • Optimized performance-to-cost ratio for high-volume integration in consumer electronics and industrial systems.

Applications

  • Tactile user interface buttons and membrane switches in medical devices and industrial control panels.
  • Robotic gripper and end-effector force feedback for precise object handling and assembly.
  • Pressure and occupancy sensing in automotive seat belts, seats, and pedal systems.
  • Wearable biomechanics and sports equipment for monitoring applied force and gait analysis.
  • Process control and monitoring for checking presence, weight, or tension in manufacturing lines.

Frequently Asked Questions

What is the output signal of the FSR402 sensor and how do I interface it with a microcontroller?

The FSR402 is a variable resistor. Its resistance decreases non-linearly as force increases. To interface with an MCU, connect it in a voltage divider circuit with a fixed pull-down resistor (typically 10kΩ) to an analog input pin. The voltage read will correspond to the applied force, requiring calibration for your specific force range.

Can the FSR402 be used for continuous, dynamic force measurement or only for static pressure?

It is suitable for both static and slow dynamic force measurements. However, its response time is not optimized for very high-frequency vibrations or impacts. For best results in dynamic applications, ensure your signal conditioning circuit bandwidth and sampling rate are appropriately matched to the expected force change frequency.

How durable is the FSR402 and what are its mounting considerations?

The PET substrate is durable but can be punctured by Sharp Microelectronics objects. Mount using adhesive backing or gentle mechanical clamping, ensuring no creases form over the active area. The IP65 rating protects against dust and water jets, but prolonged submersion or high-pressure washdown is not recommended. Avoid bending the leads directly at the sensor junction.
