Understanding Electro-Magnetic Locks

Electro-magnetic locks (or Maglocks) are very efficient low-power locks which have a range of accessories to suit most applications.

Their reliability, ease of installation, and compatibility with a wide range of security systems make them a popular choice among locksmiths and security professionals. This guide will provide an overview of electromagnetic locks, their working principles, and types.

Components of an Electro-Magnetic Lock

Electromagnetic locks are locking devices that use magnetic force to secure doors. They consist of two primary components:

• Electromagnet: This is mounted on the door frame and generates a magnetic field when powered.
• Armature Plate: Attached to the door itself, this plate is drawn towards the electromagnet, securing the door when the magnetic field is active.

Electro-magnetic locks are key components in modern access control systems. They have no moving parts making them more reliable and requiring less maintenance.

The armature and electromagnet, when energised, hold a door securely fastened by creating a powerful magnetic field. When the power is cut the armature is released, thus giving access or exit through the doorway.

Key points:

• Fail-Safe Operation: Electromagnetic locks are typically fail-safe, meaning they unlock when power is lost. This is crucial for safety in emergencies, allowing quick exit.
• Holding Force: The strength of the lock is measured in pounds-force (lbf). Common holding forces range from 600 lbf to 1,200 lbf.

Types of Electro-Magnetic Locks

Electromagnetic locks come in various types to suit different applications:

1. Single Door Maglocks: These are the most common type and are used for single doors. They are available in different holding forces, typically ranging from 600 lbf to 1,200 lbf.

2. Double Door Maglocks: Designed for double doors, these locks feature two electromagnets and two armature plates, providing secure locking for both doors simultaneously.

3. Shear Locks: A specialized type of electromagnetic lock, shear locks are designed to offer higher security by providing a shearing force between the magnet and armature plate, which prevents lateral movement.

4. Mini Maglocks: Smaller versions of standard maglocks, mini maglocks are ideal for applications where space is limited, such as cabinets or smaller doors.
