A DC electromagnetic lock is an electronic lock based on the principle of electromagnetism. Its core function is to use direct current to drive an electromagnet to generate magnetic force, thereby locking and unlocking doors or equipment.
Electrical Locking, Power-Off Unlocking: When direct current passes through the coil, a strong magnetic field is generated, attracting an iron plate and locking the door. After power is cut off, the magnetic force disappears immediately, automatically unlocking the door, meeting the "fail-safe" requirements of fire safety and security regulations.
Anti-Misoperation Interlocking: In high-voltage power equipment switchgear, disconnect switches, grounding wires, etc., DC electromagnetic locks are used to enforce operating sequences, preventing personnel misoperation and ensuring personal and equipment safety.
No Mechanical Keyhole, Enhanced Security: Opening and closing are achieved through electronic control, avoiding the duplication or misuse of traditional keys. Suitable for access control, fire escape routes, substations, and other similar scenarios.
