Power-on Electromagnetic lock
Power-on Electromagnetic lock lies in electromagnetic induction, primarily consisting of two parts: the lock body (electromagnet) and the attraction plate (armature) .
Electrically powered locking: When current flows through the coil inside the lock, a strong electromagnetic field is generated, which firmly attracts the ferromagnetic metal plate attached to the door, thus locking the door.
Power-off unlocking: After the access control system verifies the identity, the controller cuts off the power, the electromagnetic field disappears instantly, the suction plate separates from the lock body, and the door can be opened. This "power-off unlocking" design fully complies with fire escape regulations and ensures rapid evacuation of personnel in emergency situations.
Core performance indicators of Power-on Electromagnetic lock
- Safe and reliable: No mechanical latch bolt, making it less prone to being pried open; power-off unlocking design, meeting fire safety requirements and ensuring emergency evacuation.
- Strong locking force: The mainstream model boasts a static suction force of over 280kg, effectively resisting violent impacts and external prying forces.
- Simple structure: no complex mechanical transmission components, low failure rate, low maintenance cost, and long service life.
- Quick response: Locks upon power-on and unlocks upon power-off, with fast response time, suitable for high-traffic office and commercial spaces.
- Silent operation: With no mechanical friction or collision, the door opening and closing process produces almost no noise, enhancing the user experience.
Application scenarios of Power-on Electromagnetic lock
Power-on electromagnetic locks, which are powered on to lock and powered off to unlock, are safe and stable, and compatible with access control systems. They are the most commonly used electronic locks in commercial buildings, offices, residential areas, and factories.
