Hall- sensor (ook Hall-sonde, naar Edwin Hall) gebruikt het Hall – effect voor de meting van een magneetveld of elektrische stroom. Door een Hall- sensor vloeit er een elektrische stroom en wordt deze in een loodrecht daarop staand magneetveld gebracht, dan levert deze een elektrische spanning, die proportioneel is met .

Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor.
A reed sensor also works nicely, but can be limited by the glass encapsulation and size. In this article we will learn what is Hall Effect and how Hall Effect Sensors work. You can watch the following video or read the written tutorial below. Diodes offers four reliable versions of hall sensors , including Omnipolar Hall Effect Switches, Unipolar Hall Sensors , Bipolar Latched Hall Switches, and Linear Hall Latches. I tried dozens of different hall effect sensors to see which one would work best for . This note provides a basic understanding of the Hall effect and how Allegro designs and implements Hall technology in packaged semiconductor monolithic integrated circuits.
Hall – effect switches are most commonly used in sensing absolute position or proximity, because they require a south pole of sufficient strength to turn the output on and then removal of that field to turn the output off. These contactless sensing solutions require few external . Take advantage of solid-state magnetic sensing technology with Littelfuse Hall Effect sensors ! Magnetic Hall Effect Sensors Selector Guide. Options for customization are available. Browse our latest Hall Effect Sensors offers.
The heart of every MICRO SWITCH Hall effect de- vice is the integrated circuit chip that contains the Hall element and the signal conditioning electronics. These high-spee extended life sensors are often directly compatible with other electronic circuits, responding to the presence or the interruption of a . One of the primary design objectives when developing a Hall – effect sensor is to develop a device that is minimally susceptible to environmental influences. There is, however, one environmental factor, other than magnetic fiel to which many devices are deliberately made very sensitive. Many linear Hall – effect sensor ICs . Products – Next-day delivery!
