What Is an Electromagnetic Lock?
An electromagnetic lock is a lock that uses the force of an electromagnet designed for emergency exits.
Electromagnetic locks feature a security system that can be installed in any location.
Uses of Electromagnetic Lock
Electromagnetic locks are widely used for emergency exits because they enable safe escape in case of disaster.
They are also often used for general residential gates, taking advantage of their high security performance and generally low power consumption of 3 to 4W. Their high adsorption and excellent durability also make it ideal for office entrances and exits.
Electromagnetic locks can be operated by adding a peripheral device to open the lock. External opening methods include key, PIN, and contactless IC. Internal methods of opening the lock include: open switch, passive sensor, etc.
Principle of Electromagnetic Lock
Electromagnetic locks lock the door by the force of attraction by electromagnets. When the lock is energized, it becomes an electromagnet and adheres to the strike plate, locking the door.
Electromagnetic locks consist of an electronic lock, a controller, an actuator, and a power supply. By using a numeric keypad or card reader for the actuator, it can be used as a daily security lock.
In the case of power outages, the locking mechanism will disable so there won’t be a concern of being unable to enter/exit.
Electromagnetic Lock Features
Electromagnetic locks have various features due to the application of electromagnets to door locks.
1. High Locking Capacity
Electromagnetic locks lock with the force of attraction of electromagnets, which provides strong protection.
2. High Versatility
Electromagnetic locks can be installed on both open and sliding doors. If a lock is mounted on only one side of the door, it can be used as an entrance-only door or an exit-only door. Even in this use, there is peace of mind that the door will be unlocked spontaneously when the power happens to be off.
3. Easy to Unlock Even in an Emergency
Electromagnetic locks have the same locking ability as ordinary locks, but can be opened instantly with a single action such as turning off the electricity.
When an emergency escape is necessary, one must assume a state of panic in which routine actions cannot be taken. Under such circumstances, even normal actions such as turning a knob or lowering a lever are difficult. Just a simple “push” or “pull” is all that is needed to open the door.
4.High Reliability
Electromagnetic locks have a simple locking structure that adheres with its surfaces, so a slight deviation will not affect its basic operation at all.
Conventional electric locks may misalign the sensor or jamb, causing the door to malfunction or emit an abnormal signal if the door is not properly installed over time.
5. Safe for Outdoor Use
Durability is strong and can be used even under adverse weather conditions such as condensation and rain. Since there are no mechanical moving parts such as latches, gears, etc., it can be used completely waterproof. The operating environment ranges from – 40 to +60°C.
6. Easy to Install
Electromagnetic locks are basically surface-mounted on the door frame, making installation and wiring work easy. It is possible to open the door without time stress.
7. More Power-Saving Than Ordinary Electronic Locks
Electromagnetic Lock can be used with low power consumption: from 3.0W in the M62 series to 4.2W in the M82 series.
