Instructions for Use:

1. Power Supply:

   • Connect the Vcc pin to a power supply within the range of 4.5V to 24V.
   • Connect the GND pin to the ground of the power supply.

2. Output Connection:

   • The output is an open collector, so connect a pull-up resistor between the output pin (OUT) and Vcc.
   • The maximum output current should not exceed 20mA.

3. Magnetic Field Sensing:

   • Place the sensor in the magnetic field to be detected.
   • The sensor will switch its output based on the magnetic field strength:
     • Active State: When the magnetic field strength is below -65G or above +65G, the output will be low (0V).
     • Inactive State: When the magnetic field strength is between -35G and +35G, the output will be high (Vcc).

4. Temperature Considerations:

   • Ensure the operating temperature is within -40掳C to 85掳C.
   • Store the sensor in an environment where the temperature does not exceed 150掳C.

5. Handling and Storage:

   • Handle the sensor with care to avoid damage.
   • Store the sensor in a dry, cool place to prevent degradation.

6. Mounting:

   • Solder the sensor to the PCB using standard SMT techniques.
   • Ensure proper alignment and soldering to avoid shorts or open circuits.

7. Testing:

   • Test the sensor by applying a known magnetic field and verifying the output state.
   • Use a multimeter to check the output voltage level.

8. Troubleshooting:

   • If the sensor does not respond as expected, check the power supply, connections, and magnetic field strength.
   • Ensure the pull-up resistor is correctly connected and has the appropriate value.
