In stock


A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. This sensor has two output wires. The resistance between these two wires varies when the sensor is bent or when subjected to a force. Hence, this sensor can be used as a flex or force sensor.

The active sensing area of this sensor is 10 cm(~4"). This sensor is great for making whiskers for obstacle avoiding robots, gloves that sense finger positions, door position sensors, etc

The resistance of the flex sensor changes when the metal pads are on the outside of the bend (the text on the inside of the bend). The connector is 0.1" spaced and breadboard friendly. 

Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.
