Unipolar Magnetic Switch, SOT23W Package
Stock Quantity: 0
The A1120ELHLT-T is a unipolar Hall-effect switch manufactured by Allegro MicroSystems. This device is designed to provide a digital output signal in response to a magnetic field of a single polarity. It is housed in a small SOT23W surface-mount package, making it suitable for space-constrained applications. The switch detects the presence of a magnetic field and switches its output accordingly.
This unipolar magnetic switch is commonly used in various sensing and switching applications. Its compact size and reliable operation make it suitable for deployment in environments requiring magnetic field detection for position or proximity sensing.
