Description

The SOUSHINE FSR400 is a single-zone Force Sensing Resistor (FSR) based on robust Polymer Thick Film (PTF) technology. Its electrical resistance decreases predictably with an increase in the force applied to its 5.6mm circular active area, enabling precise force measurement. This analog sensor is designed for direct integration into electronic control systems.

Engineered for high-cycle applications, the FSR400 offers exceptional durability with a lifespan of up to 10 million actuations. Its ultra-thin and flexible form factor makes it suitable for embedding into tight spaces and curved surfaces, commonly used in touch-sensitive human interfaces for automotive, medical, robotics, and industrial control panels.

Key Features

  • Precision Force Sensing: Detects forces from as low as 0.1N (~30g) up to 20N (~10kg) with a non-linear, repeatable resistance response.
  • Robust PTF Construction: Utilizes durable Polymer Thick Film materials for consistent performance and long-term reliability.
  • High-Cycle Durability: Rated for up to 10 million actuations, making it suitable for repetitive-use applications.
  • Ultra-Thin & Flexible Form Factor: Enables seamless integration into space-constrained and non-planar designs.
  • Simple Two-Wire Interface: Easy to connect and condition with standard voltage divider circuits for microcontroller ADCs.
  • Cost-Effective Sensing Solution: Provides a high-value build for adding touch force control without complex mechanics.

Applications

  • Robotic gripper and end-effector tactile force feedback systems
  • Automotive dashboard and center console touch-sensitive control panels
  • Medical device input interfaces requiring proportional force control
  • Industrial human-machine interface (HMI) panels with pressure-sensitive buttons
  • Wearable devices and sports equipment for impact or pressure monitoring

Frequently Asked Questions

What is the electrical interface and how do I connect the FSR400 to a microcontroller like Arduino?

The FSR400 is a two-wire variable resistor. Connect it in a simple voltage divider circuit with a fixed resistor (e.g., 10kΩ) between Vcc and the analog input pin. One FSR lead goes to the analog pin junction, the other to ground. The analog voltage read will correspond to the applied force.

What is the force range and sensitivity of the FSR400 sensor?

The FSR400 has an actuation force as low as 0.1 Newtons (approximately 30 grams) and can measure up to 20 Newtons (approximately 10 kilograms). Its resistance decreases non-linearly with increased force, providing high sensitivity at lower force levels.

How durable is this force sensor and what is its expected lifespan?

The FSR400 is designed for high-cycle applications, with a robust Polymer Thick Film construction rated for up to 10 million actuations. This makes it suitable for repetitive-use scenarios like industrial control buttons, robotic touch sensing, and interactive consumer devices.

Can the FSR400 be used for precise weight measurement?

While the FSR400 provides a proportional analog response to force, it is best suited for touch detection, presence sensing, and relative force measurement rather than precision weighing. Its non-linear response requires calibration for specific applications if quantitative force values are needed.
