Surface-mounted access control magnets are magnets that are used to lock and unlock doors. They are usually used in conjunction with an electronic access control system and are installed on the door jamb or door side.

Surface-mounted 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.

Surface-mounted access control magnets are a popular option because they are easy to install and provide high security. 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 noticeable and may affect the appearance of a door.
