Built-in access control magnets are magnets that are installed in the door or door frame to lock and unlock the door. They are usually used in conjunction with an electronic access control system and can be integrated into the door design so that they are not noticeable.
Built-in magnets work through a magnetic field generated by a magnetic rod or core installed in the magnet system. When the door is closed, the magnetic field is activated and the door is locked. When a user wants to gain access, they must enter an access code on a keypad or use a card to deactivate the magnetic field and unlock the door.
Built-in access control magnets are a popular option because they provide high security and are not noticeable. However, they may also have limitations such as being dependent on electricity to work and being vulnerable to power outages or other technical problems. In addition, they may be more difficult to install than other types of magnets because they need to be built into the door or door frame.
