How to check Siemens anti-counterfeiting, please let us know the correct method.

I don't know what Siemens products you are talking about. As far as switches are concerned, there are the following anti-counterfeiting inquiry methods.

1, depending on the place of origin

At present, there are quite a few counterfeit Siemens switches sold in the domestic market, and many counterfeit products claiming to be "Siemens of Germany" and "Siemens of Hong Kong" are full of them. You should know that the manufacturer of genuine Siemens switches and sockets should be "Siemens (China) Co., Ltd.". Siemens has different production bases for different series of switches and sockets. The origin of Yuanjing series is "Guangdong", and the origin of Smart series and Lingzhi series used to be "Shanghai". Now Siemens China has moved the production bases of Smart series and Lexus series to "Shandong Zibo".

2. Look at the switch and socket panel

Authentic Siemens panels have good gloss and smooth surface without impurities. However, the surface gloss of counterfeit products is poor, obviously gray, and there will be burrs on the edges. Some counterfeit products even contain a small amount of impurities in the panel.

3. Open the outer frame and spray code on both sides.

After removing the outer frame of the switch, there are computer spray codes on both sides inside the switch, and each character of the genuine Siemens switch spray code is obviously composed of continuous dots, such as "-". The code-spraying characters of the fake switch here are continuous, and there is no obvious point, such as "-".

4. Look at the production date on the instruction.

The production date in the warranty instructions of genuine Siemens switches and sockets is stamped with a blue seal, while the production date in the warranty instructions of counterfeit products is printed, which is obviously a large-area printed matter.

5. Look at the copper needle in the socket.

The copper pins in real Siemens sockets are yellow and dark phosphor copper. The color of the knife is the same inside and outside, and the insert also has a U-shaped angle. The copper pin of the fake socket is plated with brass phosphor copper, with different colors inside and outside, light weight and no U-shaped angle for the insert.
