Electromagnet door locking applications
Electromagnetic locking devices are an optimum solution for different types of doors and mechanisms:
- Sliding doors
- Fire doors
- Emergency exits
- Automatic doors
- Access doors for industrial premises
Electromagnets for emergency doors
NAFSA produces door locking electromagnets for emergency exits, general access and panic doors.
These locking systems consist of a solenoid, normally fixed to the door frame, and a protective framework joined to the door itself. These two components make contact when the door is closed. When the solenoid is energised a magnetic flux is created, making the two elements attract, holding them together even if major force is applied.
Also, two different configurations are possible for these elements: fail-secure and fail-safe. Fail-secure configuration means the device remains locked when it receives no power, while fail-safe means it is unlocked when the mechanism is not powered.
