Flexiforce Sensor (A201) 100bs

The SENSOR DEMO KIT FLEXIFORCE by Parallax (Part #30056) is a development kit featuring the FlexiForce A201-25 piezoresistive force sensor from Tekscan. This sensor measures forces up to 25 lbs perpendicular to its sensing plane, functioning as a variable resistor in an electrical circuit. Resistance changes inversely with applied force, enabling measurement via an RC decay circuit compatible with Parallax microcontrollers.

Key Features

• Measures both static and dynamic forces with high sensitivity
• Simple RC circuit interface for easy integration
• Compact, ultra-thin design (0.008 in thickness) for flexible placement
• Compatible with all Parallax microcontrollers
• Minimum sensing requirement of 1 PSI on the active area

Technical Specifications

• Communication: Variable resistance inversely proportional to force
• Operating Temperature: 15 to 140 °F (-9 to 60 °C)
• Dimensions: 8.00 x 0.55 x 0.008 in (203 x 9.53 x 0.208 mm)
• Sensing Area: 0.375" diameter circle
• Resistance Range: >5 MΩ (unloaded) to ~20 kΩ (fully loaded)

Applications

• Touch-sensitive interfaces for human-machine interaction
• Alarm systems with force-based triggers
• Automotive safety, such as airbag force measurement
• Industrial monitoring in compression molding processes
• Robotics for pressure and grip feedback
