Concept and principle of waterproof magnetic lock

Concept principle of waterproof magnetic lock

The suction strength of waterproof magnetic lock is indicated by LB (pounds), and the test method is static pressure. The so-called static pressure means that the waterproof magnetic lock gradually increases the pulling force on the adsorption iron plate after the power is turned on. When it exceeds the suction force of the waterproof magnetic lock, the adsorption iron plate is instantly opened. The data of this pulling force is the pulling force value of the waterproof magnetic lock.

In addition, the force between the waterproof magnetic lock and the adsorption iron plate must be face to face and linearly pressurized, so that the suction force of the waterproof magnetic lock is the largest. The adsorption iron plate may be temporarily magnetized due to long-term magnetic induction by the electromagnet

The design of the magnetic lock (or waterproof magnetic lock) is the same as that of the electromagnet. It uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the waterproof magnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. Only a small current is needed for the waterproof magnetic lock to generate a huge magnetic force. The access control system that controls the power supply of the waterproof magnetic lock will cut off the power after recognizing the correct person, and the waterproof magnetic lock will lose its suction and the door can be opened.

Because the waterproof magnetic lock does not have a complicated mechanical structure and the structure of the lock tongue, it is suitable for passage control of escape doors or fire doors. The inside is filled with epoxy resin to protect the lock body.
