An electromechanical lock is a type of electronic lock. The closing mechanism of an electromechanical lock is activated by a solenoid or a portable electric motor. A solenoid is a type of induction coil. In a solenoid, a wire is wound around the coil in one or more layers, forming a cylinder with a core that amplifies the magnetic force. The electric motor operates by converting electrical energy into mechanical energy. The two main parts of an electric motor are the stator (fixed part) and the rotor (moving part). Overall, the operating principle of an electromechanical lock is similar to that of a conventional mechanical lock. An electromechanical lock is located on the door like a conventional lock. However, an electromechanical lock is equipped with wires and a control system on the inside of the door.
Electromechanical locks
A closer look at the operating principle of a mechanical lock shows how it works:
- When the door closes, the deadbolt of the closing mechanism activates the locking spring.
- At this point, the deadbolt itself locks the door by engaging in the keyhole. This design is advantageous because the door can no longer be forced open by forcing the deadbolt.
- The door can only be unlocked by releasing the spring locking mechanism, thereby engaging the deadbolt in the lock housing.
- The door locks automatically when it closes.
Certain types of electromechanical locks with a built-in electric motor can provide a fairly high force on the locked deadbolt, with a response time of just a few tenths of a second. This provides reliable security, but it's advisable to install such a mechanism on doors that aren't intended for everyday use.
Generally speaking, the design of an electromechanical lock combines the most successful features of a mechanical lock with the most advanced modern technologies. A wide range of unlocking devices (keys, cards, and key fobs) are available from the outside, while remote door opening is possible from the inside. In terms of external characteristics, an electromechanical lock is no different from a conventional mortise or surface-mounted lock, with the exception of the driving mechanism and associated electronics.
