Instructions for Use:
Power Supply:
- Connect the Vcc pin to a stable power supply within the range of 4.5 V to 5.5 V.
- Ensure the ground (GND) pin is connected to the system ground.
Output Connection:
- The output pin (OUT) is an open collector, requiring an external pull-up resistor to a suitable voltage level (e.g., 5 V).
- The typical value for the pull-up resistor is between 1 kΩ and 10 kΩ.
Magnetic Field Application:
- Position the sensor such that the magnetic field lines are perpendicular to the sensitive area of the sensor.
- The sensor will switch its output state when the magnetic field strength exceeds the Bop (operate point) or falls below the Brp (release point).
Mounting:
- Ensure the sensor is mounted securely to avoid mechanical stress on the leads.
- Avoid soldering temperatures above 260°C for more than 10 seconds to prevent damage.
Environmental Considerations:
- Operate the sensor within the specified temperature range to ensure reliable performance.
- Store the sensor in a dry environment to prevent moisture-related issues.
Handling:
- Handle the sensor with care to avoid static discharge, which can damage the internal circuitry.
- Use proper ESD (Electrostatic Discharge) protection measures during handling and installation.
Testing:
- Before final assembly, test the sensor using a known magnetic field source to verify its operation.
- Check for correct output levels and response time to ensure the sensor is functioning as expected.
