How to choose electromagnetic locks for smart cabinets

Selecting electromagnetic locks for smart cabinets is a key link to ensure the safe and reliable operation of the entire system. As the core component of smart cabinets, the selection of electromagnetic locks requires comprehensive consideration of multiple factors. The following is a selection guide I have summarized to help you make a wise choice:

1. Lock structure and installation method

Usually, according to the design of your own cabinet, choose the appropriate electromagnetic lock size and weight, installation hole position and other product details. Whether it is shockproof, anti-pry, sensitivity and other key factors.

Dewo electromagnetic locks have windproof, shockproof, anti-pry and other functions. At the same time, it supports optimizing the hardware structure according to the actual use of customers to make the product more suitable for consumers.

2. Durability and life

According to the actual use scenario of the cabinet, it is necessary to pay attention to the shell material, push rod, lock hook pull rod, electromagnetic coil and other important materials of the electromagnetic lock, as well as the service life. Whether it is rust-proof, whether there is a regular salt spray test, etc.
Dewo electromagnetic locks can be unlocked 200,000 times at room termperature. Most locks are made of carbon steel, galvanized iron, etc. The lock hook torsion spring is made of 304 stainless steel. The life of the electromagnet is up to 1 million times. The coil insulation tape is resistant to 100℃. The tape can melt, but it cannot burn.

3. Working voltage and current

There are 12V and 24V in general. You need to choose an electromagnetic lock with appropriate voltage, current and resistance according to your cabinet power design.

4. Door opening thrust

The conventional electromagnetic lock has a door opening thrust of 1.5kg, but if the cabinet door is larger and the material is heavier, a stronger thrust is required. If the door cannot be opened well, it will affect the end user's experience.

5. Environmental factors

There is a big difference between outdoor seaside use and bathroom use and conventional indoor use. The requirements for electromagnetic locks are also relatively high. In many perennially humid environments, it is necessary to choose electromagnetic locks and accessories with strong rust resistance.

6. Door opening method and feedback signal

Whether it is power-on or power-off, different application scenarios have different requirements, and some local fire protection also have relevant requirements.

Door status detection can provide feedback on whether the door is truly closed (whether the lock tongue is fully engaged). This is very important for the smart cabinet system to determine the door status and prevent half-close, which can significantly improve safety.

7. Electromagnetic lock interface terminal

Conventional electromagnetic locks are 4-wire (with feedback) and 2-wire without feedback. Electromagnetic lock terminals include SM2.54, XH250, etc.

Dewo electromagnetic locks support customization of lock line length, terminal interface customization, etc.

8. Cost

Different electromagnetic lock materials and different functional requirements will affect the cost of electromagnetic locks, so you need to choose a suitable electromagnetic lock according to your actual needs. On the premise of meeting all performance, safety and reliability requirements, choose the product with the best cost performance. Don't just pursue low prices, inferior locks will lead to high after-sales costs and reputation losses.

9. After-sales and warranty

Product quality and after-sales service are particularly important. If large-scale cabinets have been put on the market, problems with electromagnetic locks or other accessories will be catastrophic losses.

Dewo is the main supplier of SF Express cabinets, mainly supplying electromagnetic locks, etc. SF Express lockers have been operating stably in the market for more than 6 years.

Dewo provides a full set of smart locker kits, including lock control panels, connecting wires, Touch Screens, barcode scanners, and electromagnetic locks. It not only solves the problem of customers' decentralized procurement increasing costs, but also improves efficiency and shortens the procurement cycle through unified procurement. It also solves the problem of customers reducing risk management and optimizing after-sales problems.
