    A magnetic lock, often referred to as a mag lock, consists of an electromagnet and an armature plate. 

    The magnet is mounted inside of the door opening, which prevents tampering, while the plate is installed on the face of the door. 

    When the magnet is connected to an electrical source, it produces a strong magnetic attraction that holds the magnet tight to the plate, 

    effectively locking the door. The lock is typically powered using either the building's electrical system or a separate battery pack. 

    Because a mag lock can only be used with DC power, a converter unit must be added when relying on building power. 

    These locks are said to be 'fail-safe,' meaning that once the power goes out, the door will remain unlocked, allowing occupants to exit safely.


    Electromagnetic Theory


    Mag locks are based on the science of electromagnetism. Based on the principles of electromagnetism, 

    when a current is run through a loop of wire, or solenoid, a magnetic force will be produced. This magnetic force is of sufficient 

    strength to prevent the door from opening under a specified amount of pressure. To increase the strength of the magnetic force, 

    multiple solenoids may be used, or they may be placed around a core made of iron. 

    The magnetic effect of the solenoids not only produces its only force, but also amplifies the natural magnetism of the iron. 

    Mag locks are rated based on the amount of force they are able to withstand without failing. For example, 

    a 1,200 pound Mag Lock can withstand 1,200 pounds of force while still keeping the building secure.




    One of the biggest advantages to using a mag lock is that it can't be picked or tampered with like a traditional lock cylinder. 

    No keys are used, as the lock is generally tied into an electrical security system. These systems rely on one of four basic methods to operate the lock. 

    They are often connected to a buzzer, which must be manually released by someone inside the building before the door will open. 

    A mag lock may also be used with a keypad system, where occupants enter a numerical code to activate the lock and open the door. 

    In many commercial settings, card readers are used with these locks, making it easy to deactivate a card in the event an employee is

    terminated or loses his/her key card. Finally, in high-security situations, the mag lock may be activated by scanners that read fingerprints, 

    retinas, or facial features of an occupant before they are permitted to enter.

  • Default reader has wiegand26 output,RS232 or RS485 communication protocol.

    TCP IP  or Wifi can be customized.

  • Inside access control panel box - The controller board will have a sticker on the front labeled "S/N#"

    In the software - Under the "Controllers" section 

  • Magnetic locks and electric strikes are electrical hardware devices used to maintain the security of a door opening. 

    Both of these devices can be activated by a range of tools, including passcodes, biometric readers, keycards or buzzers. 

    When comparing magnetic locks to electric strikes, consider factors such as intended function, security needs, 

    safety egress and cost to help you choose between the two.




    A magnetic lock, or mag lock, consists of a large magnet that is installed along the top of a door frame. A metal plate, 

    or armature plate, is fastened to the door so it lines up with the magnet. When electrical power is supplied to the magnet,

    it creates a magnetic charge that keeps the magnet tightly pressed to the metal plate. This keeps the door securely locked until power is removed or interrupted.


    An electric strike must be used along with some other form of locking device, such as a lockset or exit device (panic bar). 

    Electrical power is supplied to the strike, which holds the lock bolt in place, keeping the door locked until the strike is activated by a buzzer, keycard or other device.




    With a magnetic lock, the door is always locked from both sides of the opening. This makes mag locks a very secure option for 

    areas that require high levels of security. Users must activate the lock with a keycard or other device when leaving and when entering. 

    A handle or latchset is used to operate the door, but typically has no locking function.


    Electric strikes provide security only for the exterior side of the door. Occupants can freely exit at anytime from inside the building 

    simply by turning the knob or handle, or by depressing the pad on the exit device. From the outside, the door can only be 

    unlocked with a keycard or other activating device, which signals the strike to release the lock bolt.




    All electrical hardware can be described as either 'fail-safe' or 'fail-secure.' Fail-safe hardware stays locked when 

    power to the hardware is cut, keeping the building secure. Fail-secure hardware unlocks once power is cut, 

    allowing for safe egress of occupants. A magnetic lock is always fail-safe, and unlocks automatically if power is cut.

    Electric strikes can typically be set to either of these two options using an integral switch. All fire-rated doors must be equipped 

    with fail-safe hardware for safe egress at all times.




    Because a magnetic lock is installed on the face of the door and frame, it can be installed relatively easily by most contractors. 

    It is one of the most effective types of hardware for securing both sides of a door, and provides a great door of force to keep the door secure.


    Electric strikes are usually more affordable than magnetic locks, making them a good choice for building managers on a budget. 

    It is also easier in general to meet fire and life safety codes with an electric strike than with a mag lock. 

    An electric strike is much less likely to delay egress because it can be easily operated from the inside of the building.




    Magnetic locks are among the more expensive types of door hardware. They are also fairly easy for burglars to beat, 

    because they will no longer keep the door locked if the power is cut. Finally, these locks pose a potential safety hazard in terms of slowing egress during an emergency.


    Because of the complexity of powering and installing electric strikes, they typically require skilled installers. These strikes must be chosen carefully based on the type of lock they will be used with. If the wrong strike is chosen, the lock bolt won't fit securely inside.

  • Our UHF-105 and UHF-105 UHF long range reader, it support read-write or read-only. With read-write chips, 

    you can add information to the tag or write over existing information when the tag is within range of a reader, 

    or interrogator. Read-write tags usually have a serial number that can't be written over. 

    Additional blocks of data can be used to store additional information about the items the tag is attached to. 

    Some read-only microchips have information stored on them during the manufacturing process. 

    The information on such chips can never been changed. Other tags can have a serial number written to it once and then that information can't be overwritten later.

  • Magnetic locks possess a number of advantages over conventional locks and electric strikes. For example, 

    their durability and quick operation can make them valuable in a high-traffic office environment where electronic authentication is necessary.




    1-1:Remote operation: Magnetic locks can be turned on and off remotely by adjusting the power source.

    1-2:Easy to install: Magnetic locks are generally easier to install than other locks since there are no interconnecting parts.

    1-3: Quick to operate: Magnetic locks unlock instantly when the power is cut, allowing for quick release in comparison to other locks.

    1-4: Sturdy: Magnetic locks may also suffer less damage from multiple blows than do conventional locks. 

           If a magnetic lock is forced open with a crowbar, it will often do little or no damage to the door or lock. There are no moving parts in an electromagnetic lock to break.




    1-1: Requires a constant power source in order to be secure.

    1-2: Can de-energize in the event of a power outage, disabling security.

    1-3: Expensive in comparison to mechanical locks.

    1-4: Requires additional hardware for safe operation.

  • The read range of passive tags (tags without batteries) depends on many factors: the frequency of operation, 

    the power of the reader, interference from metal objects or other RF devices. In general, low-frequency tags are 

    read from a foot or less. High frequency tags are read from about three feet and UHF tags are read from 10 to 20 feet. 

    Where longer ranges are needed, such as for tracking railway cars, active tags use batteries to boost read ranges to 300 feet or more
