Product Description
The 49E Hall IC / Sensor is a high-performance linear Hall effect sensor designed for accurate magnetic field measurement and analog signal output applications.
Unlike digital Hall sensors, the 49E provides a continuous analog output voltage proportional to the magnetic field strength. This makes it ideal for applications requiring precise position, current, or field sensing.
The sensor comes in a compact TO-92 package with three pins: VCC (positive supply), GND (ground), and Vout (analog output). It can be easily interfaced with microcontrollers, ADC circuits, and control systems.
Due to its high sensitivity and stability, the 49E Hall sensor is widely used in BLDC motor applications, current sensing, proximity detection, and automation systems.
Provides smooth and accurate analog output based on magnetic field variation, making it suitable for advanced sensing applications.
