A3144 Hall Effect Sensor for Brushless Electric Motor

The A3144 is a Hall-effect sensor commonly used for detecting magnetic fields. This digital sensor features a unipolar switch, meaning it turns on when exposed to a south-pole magnetic field of sufficient strength and turns off when the field is removed. It operates within a voltage range of 4.5V to 24V and provides a simple, reliable output signal compatible with microcontrollers and digital logic circuits. The A3144 is widely used in applications such as speed detection, position sensing, and proximity switching, offering a cost-effective and straightforward solution for integrating magnetic sensing capabilities into various electronic projects.
