Instructions for Use

1. Power Supply:

   • Connect the positive terminal of the power supply to the VCC pin.
   • Connect the negative terminal of the power supply to the GND pin.

2. Output Connection:

   • The output is an open collector, so connect a pull-up resistor between the VCC and the OUT pin.
   • The typical value for the pull-up resistor is 1k惟 to 10k惟.

3. Magnetic Field Sensing:

   • Place the sensor in the magnetic field you wish to detect.
   • The sensor will switch its output when the magnetic field strength exceeds the sensitivity threshold (Bop for operation, Brp for release).

4. Wiring Example:

   • VCC to +5V (or your supply voltage)
   • GND to Ground
   • OUT to the input of your microcontroller or other device, with a pull-up resistor to VCC.

5. Handling Precautions:

   • Avoid exposing the sensor to temperatures outside the operating range.
   • Ensure that the current through the output does not exceed 20mA to prevent damage.
   • Handle the sensor with care to avoid mechanical stress on the package.

6. Testing:

   • Apply a magnetic field near the sensor and observe the output change from high to low (or vice versa) using a multimeter or oscilloscope.

7. Storage:

   • Store the sensor in a dry, cool place away from strong magnetic fields and static electricity.
