    This force-sensing linear potentiometer (FSLP) from Interlink Electronics is a passive component with resistances that depend on the magnitude and location of the force applied at some point along the 1.4″ (3.6 cm) active length of the strip, making it easy to add novel touch interfaces or tactile sensors to your project. An external resistor (typically 4.7 kΩ to 10 kΩ) is required but not included.

    This allows a microcontroller with an analog-to-digital converter (ADC), such as an Arduino, to easily determine where and how hard the strip is being pressed, enabling advanced touch-control user interfaces (like menu navigation) or sophisticated tactile sensors. The FSLP is effectively a force-sensing resistor (FSR) that can also simultaneously sense position. The video above shows a sample project with the similar 4″ FSLP strip being used to control an LED strip: position determines the number of lit LEDs and pressure determines the LED color

    Product Dimensions:

    • Pad Dimensions: 3,6cm*1cm
    • Detection Field Dimensions: 3,6cm*1cm
    • Weigth: 0.5 gr
    • Thickness: 0,635 mm

    *Note: The output pins which are on the board are not standard output pins and soldering can be damaged to the product. For this reason, itis recommended that it is used with FCC(Flat) connectors. The product are not suitable for sensitivity and resistance measurements. Force accuracy range can vary between %5~%25 under the various conditions. The resolution is better than %0.5 of entire value range.
