Instructions for Use:
- Power Supply Connection: Connect the VCC pin to a power supply within the operating voltage range (3.0V to 24V DC). Connect the GND pin to the ground of your power supply.
- Output Connection: The output is an open collector NPN type. Connect the output pin to the load or microcontroller input pin through a pull-up resistor. Ensure the load voltage does not exceed 30V and current does not exceed 20mA.
- Magnetic Field Activation: Place a magnet near the sensor to activate it. The sensor operates at a magnetic field strength of approximately 70 Gauss and releases at around 45 Gauss.
- Temperature Considerations: Ensure that the sensor is used within its operating temperature range (-40°C to +85°C) to maintain reliable operation.
- Mounting: Mount the sensor in a position where it can effectively detect the magnetic field without physical obstruction.
