Flex Sensor 2.2″

The Flex Sensor 2.2” is a versatile and innovative component that changes its resistance based on the degree of bending. This sensor is commonly used in applications like motion detection, robotics, and gaming controllers, where detecting bends and flexes is crucial. Here’s a detailed guide on its specifications, features, and how to use it.

Specifications

• Length: 2.2 inches (55.88 mm)
• Resistance Range:
  • Flat Position: ~10KΩ
  • Full Bend: ~20KΩ to 70KΩ (depending on the degree of bending)
• Bend Angle: Up to 180 degrees
• Width: 0.28 inches (7 mm)
• Thickness: 0.012 inches (0.3 mm)
• Operating Temperature: -35°C to +80°C
