380kg Electromagnetic Locks for Doors SL-M380S

Electromagnet Lock, also simply referred to as EM Lock, is a type of locking device comprising of an armature plate and an electromagnet. Electromagnetic locks for doors are of 4 primary types – Regular Installation Lock, LZ-bracket for an in-swing door, L-bracket for the narrow door frame and U-bracket for glass door minus frame.

Find out about the top advantages of these types of door locks.

Ease of installation

These locks should be always installed on the inner side, which is the secure side. Most of the setups are mounted on the surface. For the purpose of safety, wires and cables need to be inserted into the door. Although the setup is more or less easy, there are various installation techniques for various types of locks. For instance, a U-bracket installation is likely to vary from the setup of an L-bracket lock.

High magnetic holding force

Mag locks for doors work by using the concept of electromagnetism. When these are energized, a current tends to pass through the electromagnet. The armature plate is attracted with a great force and the door is shut down. Once both plates draw each other, they are actually inseparable unless a switch to break the robust magnetic field is used. The switch works as a valid key. The power of attraction in electromagnets is much higher given the fact that a high flux density is generated within the device by the coil’s magnetic field, due to the presence of the solenoid wire within. This makes the locks safer.

Fail-safe

Maglocks for glass doors fall into the category of “fail-secure” and “fail-safe” devices. In “fail-safe” locks, once there is the loss of power from the device, the lock de-energizes automatically and releases – thus making free access possible. However, in “fail-secure” locks, the loss of power is not a cause for worry as it stays intact. In an emergency situation, such as intrusion by burglars and thieves, a fail-secure lock can be your best buddy as it will not open without a key and electricity. In emergencies such as fire hazards, a “fail-safe” lock can be useful. This makes such locks very appropriate for fire exits and emergency exits.

These are sturdy and strong locks that are safer in form and can be operated quickly. Although these are costlier than mechanical locks, the features and capability make the price tag of these devices worthwhile. In the 21^st century, the demand for such fail-proof locks is on the rise.
