What Is An Electromagnetic Lock?


Locksmith Miami would like to assist your shop’s traffic monitoring as it’s essential to obtain a locking system that safe during a fire or for controlling crowds. An electrical lock, magnetic lock, or maglock is a locking device which is composed of an electromagnet and an armature plate. There are two main sorts of electrical locking devices either fail-safe or fail secure.

Fail-secure stays locked when the power fails. The fail-safe locking device is unlocked when de-energized. For many uses, they protect a doorway for the reason of traffic control. The mag lock gets set into the doorjamb, usually along the header. Now Miami Locksmith will dive deeper into the world of magnet locks:

Electromagnetic lock basics

An electromagnetic lock provides its ultimate holding force once the door has pulled away from the magnet. For a swing type door, the mag locks are set next to the lock edge of the entryway, requiring the doorway face to get pulled away.

The mag lock goes on the locking support of the doorframe for a sliding door and when the door stays closed, the edge contacts the mag lock. However, to start, the door needs to get pulled away from the magnet.

The magnetic part of the traditional electromagnetic lock is made up of numerous E-shaped thin ferrous metal plates positioned adjacent to one another, creating a full E. Lying on their back, they shape the three metal lines on the face of the magnet.

The size and the number of the E shaped plates define the holding force of their electromagnetic lock. A copper cable twisting generates the magnetic field that results from the flow of Direct Current (DC). Then you install electronics to finish the circuitry.

All elements are placed in a housing unit. A non-ferrous potting mix fills the cavity and encapsulates the moving parts. When the fusion hardens, the surface will be machined flat to guarantee excellent holding force. Most electromagnetic locks’ ferrous metal surfaces are then plated to protect against oxidization and increase robustness. However, some mag locks have a separate compartment for the cable connections and circuitry.

A ferrous metal strike plate or armature assembly finishes the locking mechanism. Once working, this spring-loaded plate is level against the electromagnet. The strike plate offers sufficient surface area if there is settling or wear. Also, protects against tampering and could withstand removal of the mounting screws.

Power and holding force

For commercial uses, mag locks typically use 12-24VDC powered electromagnets. The amperage draw ranges from approximately 125mA to greater than 500mA in 24VDC, and also from 230mA to greater than 600mA at 12VDC. The magnet size, holding construction and force decides the attraction.

The standard electromagnetic lock developed for a doorway can be obtained using a holding force ranging from (approximately 400 pounds. to a hybrid model with 4,000 lbs. combined holding pressure). The building of the door and the jamb determine the holding pressure needed.

The magnetic lock is right for both the in-swinging and out-swinging doors. Both devices use brackets (L bracket, LZ mount, and U bracket) to compress the armature. When the electromagnet is larger than the open mounting area to the door frame filler plates can also be used to provide a big, flat mounting area around the door frame.

The magnetic lock should get fix on the safe side of the doorway, but many installments are outside mounted. For security, magnetic lock cables, and wires should be routed through the doorway frame or flush bracket with wire molding.

With in-swinging devices, the electromagnet gets install in the opening angle of the door at the doorway’s header. Maglocks may also be mounted vertically within the door opening when equipped with a full-length housing. With this setup, the armature is bolted via the doorway and oriented to partner with the face of the electromagnet.

Without swinging devices, the electromagnet stays usually set up on the side of the door header. With this setup, the armature is set on a Z shape bracket which orients the armature to partner with an electromagnet.

One thought on “What Is An Electromagnetic Lock?

  1. Doors and windows are fitted using these sensors and send an indication for
    the main panel once an entry way is breached. Therefore, avoid putting
    them near your walls and gaze after at least 3 feet distance.
    You can do this by taking principle care and putting in the exact piece of equipment that will make your
    property safer.
