QLXHBOT Magnetic Door Switch NC Alarm Double Side Tape 4 Set Brown

Description

Product Overview

The QLXHBOT Magnetic Door Switch NC is engineered to provide dependable door and window monitoring for industrial and commercial environments. Constructed with a robust ABS housing, the sensor delivers consistent performance even in demanding temperature ranges and high‑humidity conditions. The normally closed (NC) configuration means the circuit remains closed when the door is shut, instantly opening the circuit and triggering an alarm the moment the door is opened. This behavior is essential for security systems that require immediate notification of unauthorized entry.

The device features a powerful double‑side adhesive backing that eliminates the need for drilling or additional mounting hardware, simplifying installation on a variety of surfaces such as metal, wood, or plastic. Each package contains four brown‑colored magnetic reed switches, each paired with a set of sixteen screws for optional secure fastening. The compact dimensions of 2 x 1 x 0.1 inches and a lightweight design of 0.03 kilograms make the sensor unobtrusive while still delivering a reliable magnetic field detection range of more than half an inch. Compatibility with 22‑28 AWG wiring ensures easy integration into existing control panels and alarm circuits.

Usage

These magnetic door switches are ideal for securing entry points in warehouses, factories, data centers, and retail storefronts. They can be installed on doors, windows, cabinets, and even equipment enclosures where a quick, non‑invasive mounting solution is required. The NC type is particularly useful for applications that need to maintain power to lighting or ventilation systems while the door is closed, only interrupting the circuit when the door opens to signal a breach.

In addition to traditional security applications, the switches are well suited for automation scenarios such as monitoring the status of loading dock doors, controlling HVAC dampers, or integrating with building management systems to log door activity. The magnetic contact sensor’s reliable operation under vibration and shock makes it a dependable choice for environments with heavy machinery or frequent movement. Its low power consumption and corded electric source eliminate the need for battery replacements, reducing maintenance costs over the product’s lifespan.

FAQ

What is the recommended mounting surface for the magnetic door switch?

The double‑side adhesive works well on clean, flat surfaces such as metal, wood, plastic, and painted walls. For optimal performance, ensure the surface is free of dust, oil, or moisture before applying the sensor.

Can the sensor be used with battery‑powered alarm systems?

While the switch itself is designed for corded electric power, it can be incorporated into battery‑powered systems using an external power supply or relay that matches the voltage requirements of the alarm circuit.

What is the maximum operating temperature for the QLXHBOT magnetic switch?

The ABS housing is rated for temperatures ranging from -20°C to 70°C, making it suitable for most indoor industrial applications and moderate outdoor environments.

How do I test the sensor after installation?

After mounting, connect the sensor to a low‑voltage power source and a multimeter. With the door closed, the circuit should read continuity. Opening the door will break the circuit, indicating the sensor is functioning correctly.
