Instructions for Use:

1. Power Supply Connection: Connect the supply voltage between 4.5V and 24V to the Vcc pin, ensuring that the power supply is stable and within the specified range.
2. Grounding: Ensure a solid ground connection to the GND pin to maintain proper operation.
3. Output Handling: The output is an NPN open collector type. Connect a pull-up resistor between the output pin and the supply voltage when interfacing with other circuits or microcontrollers.
4. Magnetic Field Application: Position the sensor such that the magnetic field of interest is perpendicular to the sensitive area of the sensor for optimal detection.
5. Temperature Considerations: Operate the device within the temperature range of -40°C to 150°C to ensure reliable performance.
6. Mounting: Mount the sensor in a location where it will not be exposed to mechanical stress or excessive vibration which could affect its sensitivity or longevity.
7. Electrostatic Protection: Handle with care to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures during installation and handling.
