Force Sensitive Resistor (FSR 400) Small 5.08mm – High Sensitivity Pressure & Touch Sensor

The Force Sensitive Resistor (FSR 400) Small 5.08mm is a compact, high-sensitivity pressure and touch sensor designed to detect changes in applied force. Its resistance decreases as pressure is applied, making it suitable for applications where touch, pressure, or force needs to be detected electronically.

With its small sensing area, this FSR is ideal for compact electronics projects, interactive interfaces, robotics, automation, and DIY sensor applications. It can be easily connected to a microcontroller or analog input circuit to measure pressure variations.

Key Features

• Small 5.08mm sensing area
• High sensitivity to pressure and touch
• Resistance changes with applied force
• Compact and lightweight design
• Easy to interface with microcontrollers
• Suitable for analog force/pressure measurement
• Useful for robotics, automation and interactive projects

Applications

• Touch and pressure sensing
• Robotic grip and force detection
• Interactive control systems
• DIY electronics projects
• Human-machine interfaces
• Pressure-sensitive buttons and controls
• Wearable and compact sensor applications

Note: FSR sensors are generally intended for detecting relative changes in force rather than providing highly accurate absolute force measurements.
