Instructions for Use

1. Power Supply:

   • Connect the VCC pin to a power supply within the operating voltage range (3.3V to 5.5V DC).
   • Connect the GND pin to the ground of the power supply.

2. Output Connection:

   • The output is an open collector NPN transistor. Connect a pull-up resistor between the output (OUT) and VCC.
   • The typical value for the pull-up resistor is 10k惟, but it can be adjusted based on the load requirements.

3. Magnetic Field Detection:

   • Place the sensor in the desired location where magnetic field detection is needed.
   • The sensor will switch the output to low (ground) when the magnetic field strength exceeds the Bop threshold (-45 Gauss) and switch back to high (VCC) when the magnetic field strength drops below the Brp threshold (+45 Gauss).

4. Mounting:

   • Ensure the sensor is mounted in a stable position to avoid mechanical stress.
   • Keep the sensor away from high temperatures and direct exposure to moisture.

5. Handling:

   • Handle the sensor with care to avoid damage to the leads or the internal components.
   • Use appropriate ESD (Electrostatic Discharge) protection when handling the sensor.

6. Testing:

   • To test the sensor, apply a magnetic field near the sensor and observe the output state change.
   • Use a multimeter to verify the output voltage levels (high and low).

7. Storage:

   • Store the sensor in a dry, cool place within the storage temperature range (-55掳C to 150掳C).

8. Troubleshooting:

   • If the sensor does not respond as expected, check the power supply connections and ensure the pull-up resistor is correctly installed.
   • Verify that the magnetic field strength is within the detectable range of the sensor.
