Spectra Symbol's membrane potentiometer sensors not only give linear position sensing, but do so in a world-class 0.5mm in height, creating a form factor that helps engineers insert feedback position sensing right next to the device as it moves. This allows for absolute position sensing at the movement location. One important benefit from our linear potentiometer is the price. Rated at 50% to 10% of the cost of other linear potentiometers, Spectra Symbol's sensors are the best value in class.
