This section provides an overview for electromagnetic locks as well as their applications and principles. Also, please take a look at the list of 10 electromagnetic lock manufacturers and their company rankings.
Magna-lock is an electromagnetic lock that uses electromagnetic attraction designed for emergency exits.
It is characterized by its ability to build security in any location. The small size of the main unit allows installation in locations that are difficult for ordinary electric locks.
While having the same locking ability as general locks, it can be opened instantly by a single action such as turning off the electricity. Often when an emergency escape is necessary, routine actions cannot be taken. Under such circumstances, even normal actions such as turning a knob or lowering a lever can become difficult. It is important that the door can be opened simply by one action of "pushing.
Used for emergency exits because it enables safe escape in case of fire or earthquake, and instantaneous opening of doors.
Used for school gates due to ease of retrofitting and waterproofing. They are also used for general residential gates due to their high security performance and generally low power consumption of 3.6W. They are also used for office entrances and exits due to their high adsorption power and durability.
Locks can be opened by adding peripheral devices. External unlocking methods include key, PIN, and contactless IC. Internal opening methods include open switches, passive sensors, etc.
The simple face-to-surface locking mechanism means that a slight deviation does not affect the basic operation at all, and maintenance is easy. Conventional electric locks may malfunction or emit an abnormal signal due to misalignment of the sensor or jamb when the door is not properly installed over time.
Durability is strong and usable even under adverse weather conditions such as condensation and rain. Since there are no mechanical moving parts such as latches, gears, etc., it is completely waterproof in daily use. The operating environment ranges from -40°F to 140°F (-40°C to +60°C). In many use cases, it can function without problems even under direct sunlight in hot weather or during wind and snow in cold regions.
Installation and wiring work are easy, as it is basically surface-mounted on the door frame. Since there is almost no residual magnetic force immediately after the operation to open the door, it takes only 0.05 seconds from the time the switch is pressed to the time the door is unlocked. The door can be opened without time stress.
