The Flex Sensor 4.5 Inch is a resistive bending sensor designed to detect and measure angular deflection. Its resistance increases proportionally as the sensor is flexed, enabling accurate position and motion detection. Manufactured using patented technology by Spectra Symbol, it offers stable and repeatable performance. With a nominal resistance of 9kΩ when straight and up to 22kΩ at 180° bend, it is suitable for robotics, wearable electronics, and motion control applications.
