🔹 Pro Tip

💡 Thread the cylindrical body through a standard 18 mm panel hole for a professional flush-mount installation. Adjust range with a small screwdriver from the rear. The NPN open-collector output requires a pull-up resistor (4.7 kΩ to 5 V) when used with Arduino or similar MCUs.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
