Instructions for Use:

  1. Power Supply:

    • Connect the VCC pin to a power supply within the range of 4.5 V to 24 V.
    • Connect the GND pin to the ground of the power supply.
  2. Output Connection:

    • The output is an open collector configuration, requiring a pull-up resistor to VCC.
    • Connect the output pin to the input of your load or microcontroller with a pull-up resistor (typically 1 kΩ to 10 kΩ).
  3. Magnetic Field Sensing:

    • Position the sensor so that the magnetic field to be detected is perpendicular to the sensitive area of the device.
    • The sensor will switch the output to low when the magnetic flux density exceeds the operate point (BOP) and switch back to high when it falls below the release point (BRP).
  4. Temperature Considerations:

    • Ensure the operating temperature is within the specified range (-40°C to 150°C).
    • Avoid exposing the sensor to temperatures outside the storage range (-65°C to 175°C).
  5. Handling and Storage:

    • Handle the device with care to avoid damage to the leads and sensitive components.
    • Store the device in a dry, cool environment within the specified storage temperature range.
  6. Mounting:

    • Mount the device on a PCB using standard soldering techniques.
    • Ensure proper thermal management if the device is expected to operate at high temperatures.
  7. Testing:

    • Test the device by applying a known magnetic field and verifying the output state.
    • Use a multimeter to measure the output voltage to ensure it switches correctly between high (VCC) and low (GND).
