The SS49E is a small, versatile, and low-cost Linear Hall Effect Sensor that responds proportionally to the strength of a magnetic field. Unlike digital Hall sensors that only provide an ON or OFF state, the SS49E outputs an analog voltage that is linear to the magnetic flux density detected. This makes it ideal for applications requiring precise measurement of magnetic fields, current sensing, or position tracking. It operates across a wide voltage range and is packaged in a robust, easy-to-use TO-92 style case.
