A3144 Hall Effect Sensor Magnet Detector Switch

Description:

• This sensor serves as a magnet detector switch, providing a digital output that signals the presence or absence of a magnetic field. 
• When exposed to a magnetic field, the sensor generates a voltage difference perpendicular to both the current flowing through the sensor and the magnetic field itself. 
• In the case of the A3144 sensor, this phenomenon is utilized to produce a digital output, indicating the presence or absence of a magnetic field.
• Speed detection is facilitated by the A3144 sensor when used with a rotating component that includes a magnet. 
• As the magnet moves past the sensor, changes in the magnetic field are converted into a digital signal, allowing for the calculation of rotational speed.
