Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the range of 4.5V to 5.5V.
   • The typical supply current is 10mA, with a maximum of 20mA.

2. Output Configuration:

   • The output is an open collector type, requiring an external pull-up resistor to the supply voltage.
   • The output voltage when high should be less than 0.4V at a load current of 5mA.
   • The output voltage when low should be between 0.4V and 0.8V at a load current of 20mA.

3. Magnetic Sensitivity:

   • The sensor operates when the magnetic field strength exceeds the operate point (Bop) of 25 to 70 Gauss.
   • The sensor releases when the magnetic field strength drops below the release point (Brp) of -70 to -25 Gauss.
   • The hysteresis (Bhys) ensures stable switching and is typically between 5 and 15 Gauss.

4. Temperature Considerations:

   • The operating temperature range is from -40掳C to 85掳C.
   • The storage temperature range is from -40掳C to 150掳C.

5. Handling and Installation:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Ensure proper orientation during installation to align the sensor with the intended magnetic field direction.

6. Applications:

   • Suitable for applications requiring magnetic field detection, such as proximity sensing, position detection, and speed measurement.
