You use a magnetic door lock, also called a maglock or electromagnetic lock, to secure doors using the power of magnetism. This type of lock relies on an electromagnet and a metal plate. When you supply power, the electromagnet creates a strong magnetic field that holds the plate tightly, keeping the door locked. You often see magnetic locks in places where you need quick, reliable access control. These locks work well in commercial buildings, schools, and hospitals. Magnetic door lock systems offer strong holding force, fast response, and low maintenance because they have few moving parts. You can connect them to access control systems, so you unlock doors using key cards, PINs, or even your phone.
Tip: Magnetic locks provide a fail-safe feature. If you cut the power, the lock releases, making it ideal for emergency exits.
You find several key parts in every electromagnetic lock:
Electromagnet: This sits on the door frame. When powered, it creates a magnetic field.
Armature Plate: You attach this to the door. The plate sticks to the electromagnet when the lock is active.
Power Supply: It delivers a steady flow of electricity, usually 12VDC or 24VDC, to the electromagnet.
Control Board and Accessories: These include request-to-exit buttons, motion sensors, and time delay relays. They help you manage how and when the lock operates.
Mounting Brackets: You use L, Z, U, or I brackets to fit different door types and frames.
Component | Function |
|---|---|
Electromagnet | Generates magnetic field to lock the door |
Armature Plate | Attaches to door, held by electromagnet |
Power Supply | Provides continuous DC current |
Control Board | Integrates with access control systems |
Mounting Brackets | Ensures proper alignment and holding force |
You need precise installation to make sure the electromagnet and armature plate align perfectly. This ensures the magnetic lock holds the door securely. Industry standards like UL 294 and ANSI/BHMA A156.23 set requirements for performance, safety, and durability. The International Building Code requires automatic release during power outages for safe egress.
You see electromagnetic locks work because of a simple scientific principle. When you run electric current through a coil wrapped around a metal core, it turns the core into a magnet. In a magnetic door lock, the electromagnet uses a silicon steel sheet. Even a small current, such as 12 volts, can create a strong magnetic force. This force pulls the armature plate against the electromagnet, locking the door. You measure this force in pounds or kilograms. Many maglocks can withstand up to 1200 pounds of force.
The electromagnetic door lock uses a weak current, making it energy efficient. You can connect it to access control systems, so you unlock the door by cutting power when you have permission. The lock body often has epoxy resin for extra protection and durability. You get a secure, reliable, and long-lasting solution when you choose electromagnetic locks for your building.
Note: Magnetic locks are not always suitable for fire-rated or automatic doors. You should check local codes before installing them in these areas.
You see the locking process start when you supply power to the magnetic lock. The electromagnet, fixed to the door frame, receives electricity from the power supply. This current flows through a coil of wire, turning the core into a strong magnet. The armature plate, attached to the door, gets pulled tightly against the electromagnet. The door stays locked as long as the current flows.
The strength of the lock depends on several factors. The number of coil windings, the amount of current, and the type of core material all play a role. You can find magnetic locks in different sizes, each offering a specific holding force. For example, a standard size lock can hold up to 1,200 pounds of force. The table below shows how holding force increases with lock size:
Lock Size | Holding Force (lbf) | Holding Force (N) |
|---|---|---|
Micro Size | 275 | 1,220 |
Mini Size | 650 | 2,900 |
Midi Size | 800 | 3,600 |
Standard Size | 1,200 | 5,300 |
Shear Lock | 2,000 | 8,900 |
You control the locking process through an access system. When you close the door, the system supplies power, and the electromagnetic field holds the door shut. The lock stays engaged until you or the system cuts the power.
Tip: The locking process relies on the alignment of the electromagnet and armature plate. Regular checks help maintain strong holding force.
You unlock a magnetic door lock by interrupting the power supply. When you use a keycard, PIN, or smartphone, the access control system verifies your credentials. If you have permission, the system cuts the current to the electromagnet. The magnetic field disappears, and the armature plate releases. You can now open the door.
You can also unlock the door from inside using a push-to-exit button. This button connects to the control system and temporarily cuts power to the lock. Different bracket types, such as L-Bracket or ZL-Bracket, help ensure proper alignment and reliable unlocking.
Push-to-exit buttons allow safe egress.
Backup power options, like UPS or batteries, keep the lock working during outages.
Manual overrides, such as keys, provide extra safety in emergencies.
Regular cleaning and alignment checks keep the unlocking process smooth.

You see them on emergency exits and doors that must open for fire safety.
A fail secure locking device stays locked when power is lost. You use this type when you want to keep a door secure even if the electricity fails. Electric strikes often provide fail-secure operation. You find them on doors where security is more important than emergency egress, such as storage rooms or server closets.
Tip: Always check your building codes before you pick a fail-safe or fail-secure lock. Safety rules may require one type over the other.
You can choose between direct pull and shear types when you select an electromagnetic lock. Direct pull locks use a strong magnetic force to pull the armature plate straight onto the magnet. This design gives you high holding force and simple installation. Most electromagnetic door lock systems use the direct pull method. You see these on office doors, main entrances, and high-traffic areas.
Shear locks use a different approach. They hold the door by resisting sliding forces instead of pulling. The magnet and plate align so the door cannot move sideways. Shear locks give you a clean look because you can hide them in the door frame. You often use shear types on glass doors or places where you want a hidden lock.
Here is a quick comparison:
Type | How It Works | Best Use Cases |
|---|---|---|
Direct Pull | Magnet pulls plate directly | Offices, main entrances |
Shear | Magnet resists sliding | Glass doors, hidden locks |
You need to match the lock type to your needs. Think about safety, security, and how people use the door.
