About this product

The A3144E is a unipolar Hall-effect switch that changes the state of its open-drain output when a south magnetic pole approaches the sensor. It provides contactless detection for position, proximity and speed sensing, such as counting wheel or shaft rotations, detecting lid or door magnets, and sensing rotor position in brushless motors.

Frequently asked questions

What is the price of A3144E Unipolar Hall Effect Sensor Switch in Egypt?

A3144E Unipolar Hall Effect Sensor Switch currently costs 11 EGP in Egypt.

Where can I buy A3144E Unipolar Hall Effect Sensor Switch in Egypt?

A3144E Unipolar Hall Effect Sensor Switch is available from UGE. Compare the offers above to find the best price.

Does it need a pull-up resistor?

Yes. The output is open-drain, so connect an external pull-up resistor (commonly 10 kΩ) from the output to the logic supply to read the state.

Is the package SOT-23 or TO-92, and why does my magnet not trigger it?

The listing states SOT-23, but the standard A3144E designation is normally supplied in a 3-pin TO-92 package, so check the package marking before PCB layout. It only switches on a south pole, so flip the magnet if there is no response.
