Magnetic pin locks, or more accurately, magnetic door strikes, function by using an electromagnet to secure a door. Here's a breakdown:
The Core Components
A magnetic door strike consists of two main parts:
- Electromagnet: This is mounted to the door. When energized, it generates a strong magnetic field.
- Armature Plate: This is a metal plate mounted on the door frame. It's designed to be attracted to the electromagnet.
The Locking Mechanism
The locking process is relatively straightforward:
- Energizing the Magnet: When an electric current flows through the electromagnet, it becomes magnetized.
- Creating a Magnetic Field: With an electric field energizing the magnet in the door lock, a magnetic field is created that secures the armature lock and magnet in place.
- Securing the Door: This magnetic field strongly attracts the armature plate on the door frame. This magnetic attraction keeps the door securely locked.
- Releasing the Lock: When the electric current is cut off, the electromagnet loses its magnetic field, and the door can be opened.
Summary Table
Component | Location | Function |
---|---|---|
Electromagnet | Door | Creates a magnetic field when energized, attracting the armature plate. |
Armature Plate | Door Frame | Metal plate that is attracted to the electromagnet, securing the door. |
Electric Current | Power Source | Supplies the energy to energize the electromagnet. |
