What Is An Electromagnetic Lock?

The top locksmiths near Miami-Dade County would like to assist your shop’s traffic monitoring as it’s essential to obtain a safe locking system like an electromagnetic lock during a fire or for controlling crowds. An electrical lock, magnetic lock, or maglock is a locking device composed of an electromagnet and an armature plate. There are two types of electric locking devices either fail-safe or fail secure.

Fail-secure stays locked when the power fails. The fail-safe locking device unlocks when de-energized. For many uses, they protect a doorway for the reason of traffic control. The expert installer usually sets the maglock into the doorjamb, usually with the header. Allow our Commercial Locksmith services to dive deeper into the world of magnet locks:

Electromagnetic Lock Basics

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

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 complete 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.

The expert places all the components in a housing unit. A non-ferrous potting mix fills the cavity and encapsulates the moving parts. The surface will be machined flat when the fusion hardens to guarantee superior holding force. Most electromagnetic locks’ ferrous metal surfaces are 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, it protects against tampering and could withstand the 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 from 230mA to 600mA at 12VDC. The magnet size, holding construction, and force decide 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 suitable 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 provide a big, flat mounting area around the door frame.

The expert should install the magnetic lock on the safe side of the doorway, but many installments occur on the outside. Therefore, you should route the magnetic lock cables and wires through the doorway frame or flush the bracket with wire molding for better security.

With in-swinging devices, you install the magnet in the door’s door’s opening angle doorway’s header. When equipped with full-length housing, you can mount maglocks vertically within the door opening. With this setup, you lock the armature via the doorway and orient to partner with the face of the electromagnet.

Without swinging devices, the electromagnet stays usually set up on the side of the door header. The expert sets up the armature on a Z shape bracket, which orients the armature to partner with an electromagnet.

  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.
