Summary of Lock it without a key
This article explains the implementation of electromagnetic door locks, categorizing them into external types (Y280, Y350) and built-in types (Y100S). External locks use an electromagnet and metal plate for high holding force without modifying the door frame. The built-in Y100S uses a metal stick ejection mechanism with a security sensor that activates only when a magnetized plate is detected, preventing premature locking. All models operate at 12V, with some supporting 24V.
Parts used in Electromagnetic Door Lock Project:
- Electromagnet module
- Metal plate made of magnetically conducting material
- Backstop with spring damping
- Security sensor
- Permanent magnet plate
- Power supply unit
Electromagnetic door locks can be very easily implemented to almost any entry or security system.
We got used, that electromagnetic locks are a common part of entry doors to various buildings and offices. There are several types of such locks on a market, the most often they are a part of a doorframe. Each type has its pros and cons.
From some point of view, the most universal are “external” types, which can be easily implemented into any door without a necessity of an intervention to a door construction. Even such types can be found in our offer.
Y280 and Y350 are bulky locks consisting of a module with an electromagnet and a metal plate from a magnetically conducting material, which shall be mounted to a door (usually an upper portion). After switching on a power supply, a strong magnetic field will be created, sufficient to keep the door locked. A force necessary to open a door is quite considerable (2800/3500N) and normally it isn´t possible to unlock such doors by a “violence”. A positive fact is that a metal plate also contains a backstop with a spring damping a noise at locking.
A representative of “to be built in” types, is the type Y100S. It operates on a principle of a metal stick ejection, that´s why even in this case is a holding force very high, limited mainly by a door construction. A big advantage of the Y100S is that the lock already contains a security sensor against premature lock activation. After applying a power supply on the lock, “nothing happens” – the lock gets activated only after approximation of a plate with a small permanent magnet (included in a package),i.e. only after the doors are closed. All three types operate at 12V, types Y280 and Y350 can also be supplied with 24V (overall power consumption remains approximately constant).

- How do external electromagnetic locks like Y280 work?
They consist of an electromagnet module and a metal plate mounted on the door; power creates a magnetic field strong enough to prevent opening by violence. - What is the advantage of the Y100S lock type?
It includes a security sensor that prevents activation until a plate with a small permanent magnet is detected, ensuring the door is closed first. - Can the Y280 and Y350 locks be powered by 24V?
Yes, these types can be supplied with 24V, though their overall power consumption remains approximately constant compared to 12V operation. - What voltage do all three lock types operate on?
All three types (Y280, Y350, and Y100S) operate at 12V. - Does the Y280 or Y350 require intervention to the door construction?
No, external types like Y280 and Y350 can be implemented without necessity of intervention to the door construction. - What feature damps the noise at locking for Y280 and Y350?
The metal plate contains a backstop with a spring that dampens the noise when the lock engages. - How does the Y100S prevent premature lock activation?
It requires the approximation of a plate containing a small permanent magnet before the lock gets activated after power application. - What limits the holding force of the Y100S lock?
The holding force is limited mainly by the door construction rather than the lock mechanism itself.
