Window magnets are an important part of many security systems, providing a simple and effective way to monitor the opening and closing status of windows and doors. These magnets are often used in conjunction with reed switches or Hall effect sensors.Here is a description of window magnet installation locations, materials, benefits and more.
Installation location and working principle of window magnets；
It is usually installed in the removable part of the door or window frame. When the door or window is closed, the magnet is close to the sensor and keeps the circuit closed. If the door or window is open, the magnet moves away from the sensor and the circuit breaks, sounding an alarm and alerting the user.
The picture below shows a rectangular block ferrite magnets commonly used in door and window alarms, magnetized along its length
Types of window magnets;
Mainstream are are used ferrite and neodymium, ferrite material is suitable for use in cost-sensitive inexpensive alarms, as well as for applications that do not require high volume. NdFeB magnets are suitable for use in high-end alarms that require small volume and lightweight design with higher sensitivity.
As for the shape, the common shape is bar (rectangle), which is suitable for general door and window alarms, easy to install and align, some will also use round, cylindrical and so on.
This solution for door and window security systems using magnets is simple, has no physical contact, is highly reliable, and is suitable for applications such as residential and commercial.
