FIT0620 Electric Solenoid Lock


The principle of the electric solenoid lock is the same as electromagnet, which means produce magnetism by electricity, the same sexes repel and opposites attract. Power on and unlock, power off and lock. It adopts solid and durable latch hook, and the maximum stress is 735N (75kg). Pure copper electromagnetic valve coil, stable performance and temperature tolerance. It can provide a long usage life over 500 thousand times. Self-sprang design for objects from 0.5kg to 4kg and the sprang strength is adjustable. Feedback design, supporting remote status check. The lock equipped with emergency mechanic switch, supporting manual control, free from reserve power.

Compared with traditional electric solenoid locks in market, this product is designed to power off and unlock, which will help you save much power. And the mechanic lock avoids emergency of no power situations. Adjustable sprang power makes an easier control and a better space adaptability. Self-feedback design. It can be widely used in remote multi-locks and multi-cabinets projects. Particularly useful for small space and multi-cabinets projects. Such as smart cabinets, smart door locks, vending machines. It is also suitable for IOT(Internet of Things) low power consumption projects.
