Hall Effect Sensor varies its output voltage in accordance to applied magnetic flux. It is a magnetic sensor with several advantages such as high reliability, low-power consumption, and compact size. General applications are used in Notebook PCs, proximity sensors, flux meters, flow meters, current sensors, and BLDC (brushless DC) motors. Hall effect sensor is the world’s most popular magnetic sensor in consumer electronics, industrial automation, and automotive electronics.


Prolific Technology first announced its magnetic sensor product in 1997, and since then, has continually expanded its Hall Sensor product line. Prolific’s Hall sensors include features like enhanced temperature compensation, high-magnetic sensitivity, and highly concentrated distribution. Prolific’s Hall sensor products are also qualified using AEC-Q100 test standard (for automotive electronics industry) to provide the highest quality and customer satisfaction possible.
