Description

The SOUSHINE FSR407 utilizes a polymer thick film (PFT) sensing element whose electrical resistance decreases predictably with applied force. This piezoresistive principle provides a simple analog signal proportional to pressure, enabling accurate force-to-voltage conversion for embedded systems and data acquisition platforms.

Designed for reliability in demanding environments, the sensor features a robust construction suitable for repeated use in industrial, robotic, and wearable applications. Its low-profile, flexible form factor allows mounting on flat or curved surfaces, making it versatile for integration into human-machine interfaces, smart gloves, and contact detection systems.

Key Features

  • Polymer thick film (PFT) sensing element for consistent, repeatable force-resistance characteristics.
  • Flexible 35.56mm (1.4-inch) leads facilitate straightforward wiring and connection.
  • High repeatability and stability across the specified operating temperature range.
  • Simple interface compatible with standard voltage divider circuits and ADC inputs.
  • Durable construction optimized for long-term use in tactile sensing and pressure mapping applications.
  • Wide dynamic range supports applications from light touch detection to significant load measurement.

Applications

  • Robotic gripper and end-effector tactile feedback systems.
  • Wearable electronics and smart gloves for gesture and pressure sensing.
  • Human-Machine Interface (HMI) touch panels and control surfaces.
  • Medical instrumentation for patient monitoring and rehabilitation devices.
  • Industrial automation for presence detection and part placement verification.

Frequently Asked Questions

How do I interface the FSR407 with an Arduino or microcontroller?

Interface the FSR407 using a simple voltage divider circuit. Connect one lead to your microcontroller's analog input pin and the other to ground, with a pull-down resistor (typically 10kΩ) between the signal pin and ground. The sensor's resistance decreases with applied force, causing the voltage at the analog pin to increase proportionally.

What is the minimum and maximum force this sensor can reliably detect?

The FSR407 is specified for a force detection range from 20 grams (minimum) up to 10 kilograms (maximum). Performance at the extreme lower end may require careful calibration, as the resistance change per gram is less pronounced. The upper limit is defined by the sensor's structural durability and linearity range.

Can the FSR407 be used on curved surfaces or in wearable applications?

Yes, the sensor's ultra-thin profile (<0.35mm) and flexible polymer construction allow it to be mounted on slightly curved surfaces. Its durable design and flexible leads make it suitable for integration into wearable devices like smart gloves, insoles, or garments for pressure mapping and touch detection.

What is the expected lifespan and durability of this force sensor?

The FSR407 is rated for over 1 million actuation cycles, making it suitable for applications involving repeated touch or force detection. Its polymer thick film element is designed to maintain stable performance characteristics throughout its operational life, provided it is used within its specified force and temperature limits.
