All About Electromagnetic Door Locks

An electromagnetic lock, (also frequently referred to as a maglock), is basically a locking device which consists of a coil assembly and an armature plate that create a locking action when the electromagnetic coil is energised by a passing electrical current; creating a magnetic field which secures the door. 

With this type of locking mechanism in place, doors can be locked and unlocked remotely, simply by turning the power source on and off. In situ, a switch or button is positioned close by, enabling users access. To unlock the door, the switch or button is used to remove the power and de-energise the magnet, allowing the door to be opened.

What Are The Ideal Applications For A Maglock?

Perhaps the most popular application for a maglock is on an emergency exit or fire door. These mechanisms can be retrofitted very easily and require no mechanical latch to lock the door. This means that in the event of an emergency, the exit can be released quickly and easily and in the event of a power cut, the door will automatically be released.

What Are The Advantages Of A Maglock?

• Installation is straightforward as there are no complex interlocking parts
• Locking and release can be operated remotely
• Maglocks are incredibly durable, as they contain no moving parts
• No key is required – so never get locked out again!
• Magnetic locks are impossible to pick

What Are The Potential Disadvantages Of A Maglock?

• Additional hardware, such as an in situ release device, push bar, keypad or credential reader is required for safe operation of the entry and exit point
• Security is disabled in the event of a loss of power, making the entrance insecure

What Is The Holding Force Of A Maglock?

The area that connects the electromagnetic element to the armature plate is relatively large, creating a strong force that is sufficient to stand up to a substantial amount of stress.

The holding force of a maglock indicates the strength of this force and therefore a higher holding force will indicate a stronger and more secure locking device.

Here at Door Controls Direct we stock electromagnetic locks with a holding force of anything from 300kg to 1800kg, and our locking devices are suited for retrofitting on both single and double doors.
