3 Linear Field. Hall Effect Sensor. Ratiometric Output.

Description

Note:
This order comes with 3 Sensors (3 Sensors per order) but
the specs below is for one of the Sensors.
Note:
Looking at the black head of the Hall Effect Sensor, the side that has a writing of
A
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 Positive (+), the second pin is the Ground (-) and the third pin is the Output.
When there is no magnetic field present, the output voltage is half the supply voltage.
When a South pole is present, the output voltage is greater than “half the supply voltage”. The stronger the magnetic field (south pole), the higher the output voltage.
When a North pole is present, the output voltage is less than “half the supply voltage”. The stronger the magnetic field (North Field), the lower the output voltage.
Note:
1) Do not exceed the limits of the sensor especially the output current limit. 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 or 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.
