قفل الکتریکی تمام فلزی 12 ولت مناسب برای ساخت صندوق امانات

Description:
A magnetic door lock is a lock that uses an electric current to produce the magnetic force. Due to the increased strength because of the current, the doors can withstand pressure, so they can’t be forced open without the use of the confirmed access method.
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation.
The magnetic lock is suitable for both in-swinging and out-swinging doors. Brackets (L bracket, LZ bracket, U bracket) are used to orient the armature for use with both applications. Filler plates are also used to provide a large, flat mounting area on the door frame when the electromagnet is larger than the available mounting space on the door frame due to the frame's geometry.
The magnetic lock should always be installed on the secure side of the door. Most installations are surface mounted. For safety, magnetic lock, cables, and wires should be routed through the door frame or flush mount with wire molding.
Magnetic locks possess a number of advantages over conventional locks and electric strikes. For example, their durability and quick operation can make them valuable in a high-traffic office environment where electronic authentication is necessary.
Magnetic locks can be turned on and off remotely by adjusting the power source.
They are generally easier to install than other locks since there are no interconnecting parts.
The magnetic locks may also suffer less damage from multiple blows than do conventional locks. If a magnetic lock is forced open with a crowbar, it will often do little or no damage to the door or lock. There are no moving parts in an electromagnetic lock to break.
