Tekscan FlexiForce FlexiPot Strip Position Sensor - 3-Pin Male Connector

The FlexiPot Strip functions as a linear potentiometer, providing a variable resistance output. When used with a simple voltage divider circuit and a stable excitation voltage (typically 5V or 3.3V), it outputs an analog voltage signal proportional to the position of contact along its sensing strip. This signal can be read directly by a microcontroller's ADC pin.

Connect the sensor's 3-pin connector to your circuit. The outer pins connect to Vcc (e.g., 5V) and Ground. The center pin is the analog output (wiper). Connect this center pin to an analog input pin on the Arduino (e.g., A0). In your code, use `analogRead()` to measure the voltage, which corresponds to the position. Ensure your power supply is stable for accurate readings.

The active rectangular sensing area is 63.5 mm long. The specified linearity of less than ±2% means the sensor's output deviation from a perfect straight-line response (ideal linear potentiometer) across its entire range is within two percent of the full-scale output. This high linearity ensures accurate position-to-voltage conversion.

Yes, the sensor is designed on a flexible polyester substrate with a total thickness of only 0.203 mm, allowing it to conform to curved or non-planar surfaces. This flexibility makes it ideal for applications where a rigid sensor cannot be used. Avoid Sharp Microelectronics creases or bends beyond the substrate's mechanical limits to prevent damage.
