[0002] Explosion-proof door magnets are an important component configured on explosion-proof doors. They are usually used in conjunction with explosion-proof buttons, explosion-proof locks and other accessories to form explosion-proof interlocking doors. Their main function is to detect the opening and closing status of the door and trigger an alarm or take other safety measures when necessary. When the door is closed, the distance between the magnetic sensor and the magnetic trigger is very close, forming a closed circuit, and the door magnet is in normal working condition; when the door is open, the distance between the two increases, the closed circuit is disconnected, the door magnet detects the door opening state, and may trigger the alarm system. Explosion-proof door magnets are not only used in home security systems, but also widely used in commercial and industrial places such as offices, warehouses, medical institutions, etc. to ensure the safety of these places.
