Electromagnetic locks

Electroriegelnyy

— the lock, which is locked using a retractable bolt operated by an electric drive. When a signal is received (for example, from an intercom, access card, or smart home system), the bolt extends or retracts, locking or unlocking the door. This lock provides a high level of security due to its strong fixation mechanism and is suitable for both one-way and two-way control. Features include compact size, concealed installation (often in the door frame), and the ability to automatically lock when closed. Unlike an electromechanical lock, the bolt lock has no handle and is not opened by physical turning—access is granted only via a control signal. It is used in offices, banks, server rooms, and other facilities with increased security requirements.
