About this product
The A3144 is a unipolar Hall effect sensor that switches its digital output in response to a magnetic field, in this SMD SOT-23 package. It is used for detecting magnets in position sensing, rotation counting, speed measurement and door or lid detection. Its output is an open-collector type that needs an external pull-up resistor.

Frequently asked questions
What is the price of A3144 Unipolar Hall Effect Sensor SMD SOT-23 in Egypt?
A3144 Unipolar Hall Effect Sensor SMD SOT-23 currently costs 15 EGP in Egypt.
Where can I buy A3144 Unipolar Hall Effect Sensor SMD SOT-23 in Egypt?
A3144 Unipolar Hall Effect Sensor SMD SOT-23 is available from Makers Electronics. Compare the offers above to find the best price.
How do I connect the A3144 to a microcontroller?
Connect the output to an input pin and add a pull-up resistor from that pin to the supply, commonly 4.7 kΩ to 10 kΩ. The output pulls low when the magnetic field exceeds the operating threshold.
Which magnet pole activates the A3144?
The A3144 is a unipolar sensor and responds to a south-pole magnetic field of sufficient strength, not to the north pole. Confirm the orientation of your magnet, and check the datasheet of this specific SOT-23 part, as package versions can differ.
