FlexiPot Strip Position Sensor
Thin, rectangular tactile potentiometer used to identify position, location or adjust output.
FlexiPot Strip sensors have a rectangular shape, a 3-pin male connector, and are designed for use with your own electronics. These sensors are a low powered position sensor with a linear output. The sensors have a total length of 91.3 mm (3.59 in.) and a total width of 11.6 mm (0.46 in.).

The 3-pin FlexiPot functions similarly to a voltage divider. Power and ground are applied to the outside pins, and the voltage output is measured from the center pin. Also, it is important to note that the voltage output is zero when unloaded which provides the dual functionality of both linear position response and switch-like touch response. If two separate locations are loaded on the 3-pin FlexiPot, the voltage output is approximately equal to the output that is seen when the point directly between those two locations is loaded. This is useful in applications where the center point of the load applicator(s) is the position of interest:
The 2-pin FlexiPot functions similarly to a variable resistor. The resistance output will default to the maximum value, referred to as the native resistance, when unloaded and will decrease proportionally to distance. One simple way to obtain an analog voltage output from the 2-pin FlexiPot is to connect it to a power source in a voltage divider configuration by pairing it with a fixed resistor.
If two separate locations are loaded on the 2-pin FlexiPot, the resistance output is equal to the output that is seen when only one of the locations is loaded (the location that is farther from the pins). This is useful in applications where the same edge of the load applicator is always the position of interest:
