Sensors • Hall Effect Sensors

A transducer that varies its output voltage according to changes in a magnetic field, a Hall Effect sensor operates as an analogue transducer by directly returning a voltage. Within industrial environments, Hall sensors are used for proximity switching, identifying the position of a permanent magnet, detecting the speeds of wheels and shafts, and sensing current.
