		Characteristics of Magnetic Locks 
	

	In the modern field of security, magnetic locks, as an important access control device, are widely used in various places due to their unique working principles and significant performance advantages. From basic parameters to functional features, from installation methods to application scopes, every aspect of magnetic locks embodies the ingenious combination of technology and practicality. The following elaborates on their characteristics in detail. 

	
		I. Diverse Load - Bearing Capacities 
	

	The load - bearing capacity of magnetic locks is one of their core parameters. Depending on different usage environments, magnetic locks on the market offer a variety of load - bearing specifications, including 80kg, 150kg, 180kg, 280kg, 300kg, 350kg, 500kg, etc. In places with relatively low security requirements, such as the internal doors of ordinary offices, magnetic locks with a load - bearing capacity of 80kg - 180kg are sufficient to meet daily use needs. They can not only ensure the stability of the door when closed, preventing accidental opening, but also facilitate the normal passage of personnel. In high - security areas such as bank vaults, data centers, and prisons, magnetic locks with a load - bearing capacity of 500kg are the first choice. Their strong adsorption force can resist violent destruction and ensure the security of important areas. Among them, magnetic locks with load - bearing capacities of 280kg and 500kg are the most common. 280kg magnetic locks are suitable for most commercial places and ordinary public buildings, striking a good balance between security and cost; 500kg magnetic locks are more often used in special places with extremely high security requirements. 

	
		II. Flexible Installation Classifications 
	

	The installation methods and applicable door types of magnetic locks reflect their high degree of flexibility. In terms of installation methods, they can be divided into embedded electromagnetic locks and surface - mounted electromagnetic locks. Embedded electromagnetic locks are installed by embedding the lock body into specific positions of the door and door frame, perfectly integrating the entire access control system with the building structure. This not only looks aesthetically pleasing but also makes it less vulnerable to external damage. They are often used in places with high requirements for aesthetics and security, such as high - end office buildings and hotels. Surface - mounted electromagnetic locks are installed on the surface of the door and door frame. The installation process is relatively simple and quick, making them suitable for places with high requirements for installation convenience, such as temporarily built sites and renovated old buildings. According to the number of door leaves, magnetic locks are also classified into single - door and double - door magnetic locks. Single - door magnetic locks are suitable for access control of single - leaf doors and can be adapted to wooden doors, glass doors, metal doors, etc.; double - door magnetic locks are specifically designed for double - door openings, ensuring that both doors are firmly locked when closed. They are commonly used in scenarios such as shopping mall entrances and warehouse gates. 

	
		III. Stable Power Supply Characteristics 
	

	In terms of power supply, magnetic locks generally obtain electricity from automatic door operators. The operating voltage is DC12V, and the operating current is ≤250MA. Such power supply parameters enable magnetic locks to operate stably while consuming low power, meeting the requirements of energy conservation and environmental protection. The DC12V operating voltage falls within the safe voltage range, greatly reducing the risk of electric shock. Even in special environments such as humid conditions, it can ensure the safety of personnel. The low operating current ensures that magnetic locks do not generate excessive heat during long - term operation, reducing the possibility of equipment failure due to overheating and extending the service life of magnetic locks. 

	
		IV. Unique Built - in Devices 
	

	The built - in surge absorber in magnetic locks is one of its key components. Due to the principle of electromagnetic induction, when the magnetic lock is powered off, the generated magnetism does not disappear immediately. This will cause the door to be unable to open in a timely manner, bringing great inconvenience to personnel access and even potentially delaying the escape time in emergency situations. The function of the surge absorber is that once the power is cut off, it can quickly form a short - circuit, making the magnetism of the magnetic lock disappear rapidly and enabling quick door opening. This device not only improves the convenience of using magnetic locks but also buys precious time for personnel evacuation in emergencies such as fires and earthquakes, greatly enhancing safety. 

	
		V. Special Usage Requirements 
	

	Magnetic locks have special usage requirements. The force between the electromagnetic lock and the adsorption iron plate must be applied face - to - face and in a straight line. Only in this way can the electromagnetic lock exert its maximum suction force and ensure the stability of the access control system. If there is a deviation in the installation angle, even a very small one, it will cause a significant decrease in the suction force of the magnetic lock, and the security of the door cannot be guaranteed. In addition, due to the long - term magnetic induction of the electromagnet, the adsorption iron plate may be temporarily magnetized. The magnetized adsorption iron plate will retain a certain degree of magnetism. Although this magnetism is usually weak, in places sensitive to magnetic fields, such as precision instrument laboratories and electronic equipment workshops, it may interfere with equipment. Therefore, special attention should be paid when using magnetic locks in these places, and corresponding demagnetization measures should be taken. 

	
		VI. Wide Range of Applications 
	

	Magnetic locks have a very wide range of applications, covering almost all common types of doors, including wooden doors, glass doors, metal doors, and fire - rated doors. For wooden doors, magnetic locks can be firmly fixed with appropriate installation accessories to provide reliable access control; glass doors usually have frameless or framed designs, and magnetic locks can be adaptively installed according to different glass door structures, achieving security protection while ensuring aesthetics; metal doors have high strength, and the strong suction force of magnetic locks can perfectly match them, ensuring the stability of metal doors when closed; in the application of fire - rated doors, magnetic locks not only meet the daily access control management requirements but can also cooperate with fire - fighting systems to achieve power - off door opening in case of fire and other emergencies, ensuring the unobstructed evacuation route for personnel and complying with fire safety regulations. 

	In conclusion, with their diverse load - bearing capacities, flexible installation classifications, stable power supply characteristics, unique built - in devices, special usage requirements, and wide range of applications, magnetic locks play an important role in modern access control systems. With the continuous progress of technology, magnetic locks will continue to be optimized and upgraded, bringing a safer and more convenient access control experience to people's lives and work.
