Description

The RFP602 operates on the principle of force-sensitive resistance (FSR), where applied pressure decreases the internal resistance of a specialized polymer thick film. This change in resistance is inversely proportional to the applied force, allowing for precise force or pressure measurement through a simple voltage divider circuit connected to a microcontroller’s analog-to-digital converter (ADC).

Its flexible and ultra-thin construction enables seamless integration into ergonomic designs, wearable devices, and human-machine interfaces where space is constrained. The sensor provides a reliable, repeatable response across its specified force range, making it suitable for both static load monitoring and dynamic touch detection applications.

Key Features

  • Force-Sensitive Resistor (FSR) technology for analog force measurement.
  • Compact 5mm circular sensing area for localized pressure detection.
  • Flexible substrate allows for conformal mounting on curved surfaces.
  • Robust operating range from -30°C to 60°C for environmental resilience.
  • High-speed sub-millisecond response time enables real-time interaction.
  • Simple two-terminal interface for easy integration with 3.3V or 5V systems.
  • Durable construction designed for high-cycle life in interactive applications.
  • High-value build optimized for cost-sensitive, high-volume integration.

Applications

  • Interactive force-sensitive controls in game controllers and musical instruments.
  • Tactile pressure sensing in medical devices and rehabilitation equipment.
  • Occupancy or touch detection in automotive seating and industrial HMIs.
  • Wearable device integration for activity monitoring and gesture recognition.
  • Robotic gripper force feedback and delicate object handling systems.

Frequently Asked Questions

What is the output signal of the RFP602 sensor and how do I interface it with a microcontroller?

The RFP602 provides a variable analog resistance that decreases with applied force. Interface it by creating a simple voltage divider circuit with a fixed resistor (e.g., 10kΩ) between the sensor's two pins. Connect the junction to your microcontroller's ADC input pin to read a voltage proportional to the force.

What is the recommended circuit for reading the RFP602 sensor?

Use a standard voltage divider. Connect one sensor pin to Vcc (3.3V or 5V). Connect the other sensor pin to one end of a fixed pull-down resistor (typically 10kΩ to 100kΩ). Connect the other end of the fixed resistor to GND. The ADC measurement point is the junction between the sensor and the fixed resistor. Calibration is required to map ADC values to specific force levels.

Can the RFP602 sensor be used for continuous static load monitoring?

While capable of static force measurement, thin-film FSRs can exhibit some creep under constant load over extended periods. For best accuracy in static applications, periodic zeroing or calibration is recommended. They are highly effective for dynamic force detection, touch events, and short-term load monitoring.

How durable is the RFP602 sensor, and what is its lifecycle?

The RFP602 is designed for high-cycle applications typical in human interfaces. Its polymer-based construction offers good mechanical durability for millions of actuations under normal force ranges. Avoid Sharp Microelectronics objects, excessive over-force (beyond 5kg), and bending directly on the active sensing area to maximize lifespan.
