Hall Sensor AH49E

The AH49E Hall sensor is a type of magnetic sensor that utilizes the Hall effect to measure magnetic fields. It is commonly used in various electronic applications where accurate and reliable detection of magnetic fields is required.

The Hall effect refers to the phenomenon where a voltage difference is generated across a conductor or semiconductor when it is subjected to a perpendicular magnetic field and a current flow. This voltage, known as the Hall voltage, is directly proportional to the strength of the magnetic field.

The AH49E Hall sensor, manufactured by Diodes Incorporated, is a popular choice due to its small size, low power consumption, and high sensitivity. It operates based on the principle of a unipolar Hall switch, which means it detects only one polarity of the magnetic field.

One of the key features of the AH49E Hall sensor is its wide operating voltage range, typically from 2.5V to 20V, which makes it compatible with various electronic systems. It also has a built-in voltage regulator that helps maintain a stable output voltage regardless of the supply voltage fluctuations.

The output of the AH49E Hall sensor is a digital signal that changes its state when the detected magnetic field exceeds a specific threshold. This makes it suitable for applications such as position sensing, speed detection, proximity detection, and non-contact switching.

The AH49E Hall sensor is commonly used in automotive systems for applications like wheel speed sensing, throttle position sensing, and gearbox position sensing. It is also found in industrial equipment, robotics, consumer electronics, and other electronic devices where precise magnetic field detection is required.

Overall, the AH49E Hall sensor offers a compact and efficient solution for magnetic field detection. Its reliability, sensitivity, and ease of integration make it a popular choice for a wide range of applications in various industries.
