Instructions:

1. Mounting: Ensure the EE-SM3 is mounted on a PCB with appropriate soldering techniques suitable for SMD components.
2. Power Supply: Connect the supply voltage between 1.8V and 6V to the Vcc pin, ensuring not to exceed the maximum operating current.
3. Signal Detection: Place the object or component to be detected within the detection distance range of 0.5mm to 2mm for reliable operation.
4. Output Handling: The output can drive loads up to 50mA. For higher current applications, use an external transistor or driver.
5. Temperature Considerations: Operate within the specified temperature range to avoid damage or unreliable performance.
6. Handling Precautions: Handle with care to prevent damage from electrostatic discharge (ESD).
