What is the solenoid of the lock?

Lock solenoid is a type of electrical locking mechanism that uses an electromagnetic device containing a firmly wound metal wire coil called solenoid, which provides mechanical energy that opens and closes the lock. Solenoid locks are often used as door locks and are also used to lock other things such as cabinets or drawers. They are particularly common for doors that are locked and unlocked remotely, such as the main door of many housing complexes or situations where security is a special problem. The wire is curled around the long, often cylinder -shaped core made of iron or some other ferromagnetic material that is located so that it can move closer or further from the center of the coil when force is applied. When the electric current passes through the wire, it generates a magnetic field that moves the nucleus and turns into the Energy Energy into the mechanical energy and the production of linear movement. This allows the solenoid to open or close the screw in the lock.

solenoid locks have several features that make them desirable in many applications. Unlike pure mechanical locks, the solenoid of the lock can open and close without being physically present to run it, which is useful for locks that receive instructions for opening and closing from a separate location or do so automatically according to the preset timer or sensor signals without direct human input. They can also be designed to be unlocked by other things than a physical key such as a password; signal from a radiofrequency identification device or a personal digital assistant; or biometric data such as fingerprints, voice prints or retina scanning.

Another useful function is that, depending on the solenoid design, the core can be placed so that the activation of the electric current either pushes the core outwards, thrown a screw and closedThe lock, or chooses the core inward to open the lock. The lock that uses a magnetic field to close the lock automatically opens in the event of a failure or "open" failure, while a lock that uses a magnetic field to open the lock, performs the opposite, and "closed" failure.

This is a useful attribute of solenoids and an important design because it determines how the lock will respond in the event of a device failure or loss of electricity. For example, the locking of solenoids used on the doors of enterprises or residences will usually be designed to fail open, so in the event of a dangerous event that causes power failure, such as fire in the building, people will be able to escape the building without restriction. On the other hand, in the case of some solenoid locks, such as locks on a vault, safe or wardrobe containing money, valuables, or other potential goals, such as sensitive government or business information, the lock is desirable that the energy loss is not suddenly injuredElne.
