Instructions for Use
Power Supply:
- Connect the Vcc pin to a power supply within the operating voltage range (4.5V to 24V).
- Connect the GND pin to the ground of the power supply.
Output Connection:
- Connect the OUT pin to the input of your control circuit.
- Ensure that the output is connected to a pull-up resistor to the supply voltage (Vcc).
Magnetic Field Application:
- Apply a magnetic field to the sensor in the direction specified in the datasheet.
- The sensor will switch its output state when the magnetic field strength exceeds the Bop threshold and will return to the original state when the magnetic field strength drops below the Brp threshold.
Temperature Considerations:
- Ensure that the operating temperature does not exceed the specified range (-40°C to 85°C).
- Store the device in an environment within the storage temperature range (-40°C to 150°C).
Handling Precautions:
- Handle the device with care to avoid static discharge, which can damage the sensor.
- Avoid exposing the device to excessive mechanical stress or chemical substances.
Testing:
- Test the sensor by applying a known magnetic field and verifying the output response using a multimeter or oscilloscope.
- Ensure that the quiescent current and response time meet the specified values.
