Hall effect sensors use changes in electromagnetic fields to detect the speed, position and direction of moving parts such as wheels, gears, and shafts. The devices can also be used to measure fluid levels by sensing floating actuators. Littelfuse offers Hall effect sensors in flanged, barrel, ...
Hall-effect sensors measure fields and detect positionJeffrey Dierker
Two-Latch Implementation With Two Examples of a Single Dual- X2SON Package Latch Implementation BLDC motor commutation Three latches are used to detect the speed, direction, and position in this application. By precisely synchronizing the current through the coils on the stator, the permanent ...
A Hall-effect sensor stationed near the rotor (rotating part of the motor) will be able to detect its orientation very precisely by measuring variations in the magnetic field. Sensors like this can also be used to measure speed (for example, to count how fast a wheel or car engine cam ...
Hall-Effect Sensors Applications Guide Answering common sensor IC technology questions such as "What is Hall-effect?"Allegro MicroSystems uses the latest integrated circuit technology in combination with the century-old Hall effect to produce Hall-effect sensor ICs. ...
Brushed motors, however, do not require Hall sensors for motor commutation. In addition to spinning the wheels, vacuum robots require a mechanism to tell the speed and direction at which the wheel is moving, which is referred to as incremental encoding. The Hall-effect latches used for BLDC ...
Hall effect sensors and analog joysticksare both commonly used in game controllers, but they function differently and have their own set of advantages and disadvantages. Analog joysticks, also known as ALPS and potentiometer-based joysticks, use a variable resistor to detect the position of the joys...
