Instructions for Use:
Power Supply:
- Connect the VCC pin to a power supply within the range of 2.5 V to 5.5 V.
- Ensure a stable power supply to avoid erratic behavior.
Ground Connection:
- Connect the GND pin to the ground of your circuit to provide a reference point.
Output Connection:
- The output is an open collector, so connect a pull-up resistor between the output pin and VCC.
- The typical value for the pull-up resistor is 1 kΩ to 10 kΩ.
Magnetic Field Application:
- Apply a magnetic field perpendicular to the surface of the sensor to trigger the switch.
- The switch will activate when the magnetic field strength exceeds the BOP threshold (35 Gauss typical).
- The switch will deactivate when the magnetic field strength drops below the BRP threshold (20 Gauss typical).
Temperature Considerations:
- Ensure that the operating temperature remains within the specified range (-40°C to +85°C) to maintain reliable operation.
Handling Precautions:
- Handle the component with care to avoid static damage.
- Store in a dry environment to prevent moisture damage.
Testing:
- Test the device in a controlled environment to ensure it meets the required specifications.
- Use a multimeter to verify the output state (high or low) when applying and removing the magnetic field.
