The screws provided by the real Siemens are longer and the thickness of the screws is the same. The fake Siemens matching screws are shorter and the screw tips are thinner.

Panel gloss: The genuine Siemens panels have good gloss, while the fake ones have rough, dark surfaces and rough workmanship.

The left one is the original one and the right one is the imitation one. The difference is very simple. You can tell from the appearance that the original cable TV hole is black while the imitation one is white. The genuine outer metal ring that connects the shield is made of very good material, and has a grid of concavities and convexes, which can make the plug and socket of the closed line more closely in contact, which is very user-friendly. The imitation product is a thin circle of iron-like material, and even the gaps at the joints of the circles are terrifyingly large.

Brand store: Siemens switch

The circuit board part on the back of the Siemens cable TV socket. This time, the position is changed. The left is a fake and the right is the original. The same thing is clear at a glance. The circuit on the left The board and solder joints are very rough, the right side is neat and smooth.

The pressing pieces and fixing clamps of the imitation products are made of ordinary alloy, while the genuine ones are made of pure copper, clean and bright. In addition, the production date on the panel of fake products is often around 2005, while genuine products should be at least after the end of 2006.

Here is a close-up of the authentic product. There are clear trademarks and numbers in the blank space next to the module. Next is a comparison of the phone sockets. From the front, there is not much difference. It mainly depends on the smoothness of each opening. The fake product There are often many small burrs. In addition, the color of the counterfeit product is slightly yellower than that of the original product. The phone jack protective film that can be pushed up and pulled down does not feel very smooth, and may even shrink in if you use too much force. Have you figured out which one it is?

On the back, the left side is authentic and the right side is fake. The production dates of these fakes are all 2005XXXX. The module color of the fakes is obviously yellowish.

On the back of the genuine product, the blank spaces on both sides of the module have clear digital markings like the closed-circuit sockets. There is a clear MADE IN CHINA directly above the module, and the SIEMENS trademark LOGO below.

On the back of the fake product, there is no serial number or origin mark. The most terrible thing is that you can see the huge circular burr formed by the mold gate on the upper right mounting hole.

On another fake product, the production date is marked as 20050811, and so is this one. Even the large burrs on the cable plug have not been removed.

Siemens official website query

Starting from June 2009, all Siemens switches have double anti-counterfeiting. The first level of anti-counterfeiting is the anti-counterfeiting label affixed to the packaging bag, and the second level is The 20-digit anti-counterfeiting code on the product holder. If sent by text message, no abnormality can be found.

At this time, you can go to the official website of Siemens China to check

By the way, let me tell you a little tip (the premise is that the appearance and quality of the product are not much different from the original product, from product packaging to anti-counterfeiting code , manuals, etc. are all highly simulated):

The phones, network cables, TV sockets, and switches sold by JS are relatively expensive, so the counterfeiting profits are higher. Generally, the number of these sockets is not large, so this You need to check all of them; generally if there are no problems in these queries, they should not be fake. At the same time, to be on the safe side, it is best to conduct random inspections on the 5-hole sockets. If there are no problems, it should be almost genuine.
