2.2 Inch Flex Sensor – 10KΩ Resistive Bend Sensor

The 2.2 Inch Flex Sensor is a resistive bend sensor designed to detect angular deflection by varying its resistance. When bent, the resistance increases, especially when the metal pads are positioned on the outer side of the bend. It features a 10KΩ nominal flat resistance and supports up to 0.5W continuous power. With 2.54 mm pin spacing, it is breadboard-friendly and easy to integrate into microcontroller-based systems. Ideal for robotics, wearable devices, gesture detection, and motion control applications.
