Door profile magnets are magnets used to lock and unlock doors. They are typically used in conjunction with an electronic access control system and are installed on the door jamb or door side, depending on the design of the magnet system.

Door profile magnets work through a magnetic field generated by a magnetic rod or core installed in the door profile. When the door is closed, the magnetic field is activated and the door is locked. When a user wants to access, they must enter an access code on a keypad or use a card to deactivate the magnetic field and unlock the door.

Door profile magnets are a popular option for access control because they are easy to install, reliable, 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.
