Linear potentiometer - overview of characteristics

Linear potentiometers are linear sensors. Sensors by WayCon are well suited to measure distance and way, while maintaining a high resolution. Our wide range of linear potentiometers is constantly developed to provide the best possible solutions. Because of the wide variety of their housings, linear potentiometers are used in many different applications.
