Rotation-based devices such as dials, joysticks, thermostats, electronic steering assemblies, and motor-controlled joints typical to gimbals or robotic arms all rely on the ability to accurately define angular position. While there are means to monitor rotation angle using mechanical contacts, these types of sensors are prone to wear out with use and can suffer performance loss in cases where dirt and grime are present. Hall-effect sensors are a contactless sensing alternative which can offer longer product life, improved reliability, and higher performance for angle sensing.
