Description
Product Overview
The GAGALOR Flush Mounted Door Alarm Sensor is engineered to provide a dependable normally‑closed (NC) magnetic contact solution for both doors and windows. Constructed from high‑impact ABS plastic, the sensor housing resists corrosion and mechanical stress, ensuring long‑term reliability in demanding industrial and commercial environments. With a compact footprint of just 1.06 x 0.47 x 0.47 inches and a lightweight of 0.634 ounces, the device can be seamlessly integrated into existing wall or frame structures without compromising aesthetic integrity. The sensor operates at a maximum of 28 V and 0.2 A, delivering a low power consumption of 3 W, which makes it compatible with a wide range of alarm control panels and power supplies. Its ½‑inch (approximately 13 mm) operation distance allows for flexible installation on various door and window sizes, while the 22‑28 AWG terminal wiring hole simplifies connection to existing wiring harnesses. The package includes two identical sensors, providing a cost‑effective solution for multi‑point security coverage.
Usage
Designed for versatility, this magnetic contact switch is suitable for a broad spectrum of applications ranging from residential home security systems to large‑scale industrial facilities. Install the sensor flush within the door or window frame to keep it hidden from view, reducing the risk of tampering or accidental damage. The sensor’s NC configuration ensures that the alarm circuit remains closed when the door or window is closed, and opens instantly upon separation, triggering an alert in real time. It works flawlessly with standard alarm panels, smart home hubs, and building management systems that accept 28 V input, making it an ideal choice for retrofitting older installations or for new construction projects. Because the device does not require batteries, maintenance is limited to periodic visual inspections and wiring checks, which can be performed quickly by qualified technicians. The sensor’s robust ABS construction also makes it suitable for harsh environments such as warehouses, factories, and outdoor enclosures where temperature fluctuations and dust are common.

FAQ
What type of wiring is required for installation?
The sensor is designed for 22‑28 AWG stranded or solid wire. Connect the two terminals to the alarm panel’s normally‑closed input according to the wiring diagram provided with your control system.
Can this sensor be used with battery‑powered alarm systems?
Yes, the sensor can be powered by a battery‑backed alarm panel as long as the panel supplies a stable 28 V source. The low current draw (0.2 A) ensures minimal impact on battery life.
Is the sensor suitable for outdoor installation?
While the ABS housing offers good resistance to moisture and temperature variations, it is recommended to install the sensor in a protected enclosure or behind a weather‑proof frame for prolonged outdoor exposure.
How does the ½‑inch operation distance affect performance?
The ½‑inch (approximately 13 mm) magnetic gap provides reliable detection for most standard door and window frames. It allows the sensor to remain hidden while still delivering consistent contact switching.
What warranty does GAGALOR provide for this product?
GAGALOR offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our support team for troubleshooting or replacement assistance.
