The T568R Wireless Door/Window Sensor uses advanced Hall-switch technology to detect the opening and closing of doors and windows in real time. With strong anti-interference performance, ultra-low power consumption, and 433 MHz wireless transmission, it provides reliable security for homes, offices, shops, and warehouses.

Smart Magnetic Sensor for Door & Window Protection

This wireless sensor instantly detects when a door or window is opened and sends an alarm signal to your security host. It uses ASK modulation and operates at 433 MHz, ensuring stable and long-distance communication with minimal interference.

Accurate Real-Time Detection

Thanks to Hall-switch sensing technology, the system detects even the smallest movement between the sensor and magnet—perfect for anti-theft protection.

Easy Installation Anywhere

Simply mount the main body on the door frame and the magnet on the moving door or window. Ensure a gap of ≤20mm for accurate detection (as shown in the installation diagram) .

Ideal for All Security Setups

Suitable for residential homes, commercial shops, offices, warehouses, and storage rooms.

🛠 INSTALLATION GUIDE

1. Install the main sensor on the fixed door/window frame.

2. Install the magnet strip on the moving part of the door/window.

3. Ensure the distance between them is ≤20mm for accurate activation.

4. Avoid metal surfaces or strong magnetic fields (as warned in PDF).

5. Insert the CR2450 battery, switch to ON, LED will blink once confirming startup.

📡 HOW IT WORKS

• When the door/window opens → magnet separates → sensor sends wireless alarm signal.

• When closed → magnet aligns → sensor returns to normal mode.

• When tampered → LED flashes & alarm triggers.

🙋 FAQs
