Description

Note: Looking at the black head of the Hall Effect Sensor, the side that has a writing of 460S is the top face and the other side is the bottom face. Place the Hall Effect Sensor so that the bottom face is against the table and top face is the face that you can see. Looking down at the top face with the pins facing towards you. The first pin is the Vs, the second pin is the Ground (-) and the third pin is the Output.

The output current flows when the South pole is facing the top face and remains on. It then turns off when the North pole is facing the same top face.

Notes:

1) Do not exceed the maximum limits of the sensor. Use a resistor or other components when needed.

2) For applications requiring a higher output current greater than the maximum output current rating, use an amplifier such as a transistor to carry that amount of current.

3) For DC Motor applications, remember to use a diode to drain the spike voltage that occurs when the current is automatically turned off.

Notes:

1) The device has a safety feature. It will shut down after the output current  is over the output current 90mA for 160us (typically). The device will re-start up operating after resetting the supply voltage.

2) Magnetic characteristics are for design information, which will vary with supply voltage, operating temperature and after soldering.
