What is EM Lock?

An EM lock, or electromagnetic lock, is an access control device that uses magnetic force to secure a door. It consists of an electromagnet installed on the door frame and a metal armature plate fixed on the door. When power is supplied, the magnet creates a strong magnetic bond that keeps the door locked. When access is granted or power is cut, the magnetic force releases, allowing the door to open.

EM locks ensure the prevention of unauthorized entry into a specific room or protection zone in an industry and a restricted area in an office. These locks are stronger than any regular ones and provide a quick response. A major benefit of using these locks is that they automatically lock during a power cut or outage, preventing anyone from entering the restricted area. Users can get these locks to integrate with other security devices, such as a card reader or biometric reader, to improve security.
