Magnetic Hall Effect Sensor - A3144
- Product Code: A3144
- Availability: In Stock
The A3144 is an integrated Hall effect nonlatching sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch.
