Spectra Symbol Flex Sensor FS-L-095-103-RH 95mm - Female Plain Housing Connector

Connect one pin of the sensor to the Arduino's 5V supply through a fixed resistor (e.g., 10 kΩ) to form a voltage divider. Connect the sensor's other pin to an analog input pin (e.g., A0). The Arduino will read a variable voltage that changes with the bend angle. You will need to map the ADC reading to a corresponding angle in your code, typically requiring a calibration step.

The 25 kΩ nominal resistance is the sensor's approximate resistance when flat (unbent). This value forms the baseline for your voltage divider circuit. As the sensor bends, the resistance increases, changing the voltage at the analog input pin. The ±30% tolerance means the actual flat resistance of individual units may vary, so calibration for each sensor is recommended for precise measurements.

Yes, the FS-L-095-103-RH is designed for repeated flexing cycles and is suitable for dynamic applications like robotic joints or gesture controllers. Its robust strip construction can withstand mechanical stress. For optimal longevity, avoid Sharp Microelectronics bends beyond its specified mechanical limits and ensure mounting minimizes stress concentration at the connector junction.

The female plain housing connector provides a secure, solderless interface for electrical connection. It accepts standard male pins or headers, simplifying integration into breadboards, custom PCBs, or wiring harnesses. This feature speeds up prototyping and ensures reliable connections in final assemblies, reducing the need for direct soldering to the sensitive sensor strip.
