49E / AH49E Linear Hall Effect Sensor — Analog Output
The 49E (AH49E) is a linear Hall Effect sensor that provides a continuous analog voltage output proportional to the applied magnetic field strength. Unlike switching Hall sensors, the 49E outputs a ratiometric analog signal, making it perfect for precise magnetic field measurement, current sensing, and motor position feedback applications.
