The annual 3.15 International Consumer Rights Day is coming again
Follow routine routines
Every year
Will come
Evening party without song and dance
But this evening
There are "dumps" that make us thrilling
The audience held seeds in their hands
Against those adulterated cosmetics and black heart takeaways
Barabara å¨å¨å¨å¨@#Â¥%...&
then
Usually some "informal" big bosses are frightened
I'm afraid the board hits my ass
One hundred thousand urgent public relations can not save themselves
In fact, this is not the case in the industrial control circle.
As small as a switch, as large as a device, buying fake goods not only brings inconvenience to their own use, but also seriously damages their lives.
such as:
For 3.15, everyone is adhering to a happy and sad attitude, and the joy is: Some fake and shoddy products were exposed on this day (at least a little knowing the truth). Sadly, why manufacturers can't pay attention to the rights of consumers every day, letting them become 3.15 every day.
So rather than looking forward to 315, it's better to be the master of yourself. How is the main method? That is - instead of waiting for a long period of "extinction of fake goods," it's better to be the "eye of the eye" to learn how to identify counterfeit goods!
As follows, with the five categories of products that are often "imitations" by industrial control circles, let's take a look at what exactly is "the true and false beauty of the Monkey King".
1. Relay disaster area - Omron MY2JMY2NJMY4JMY4NJ etc.
Contacts: Authentic MY4 series relays use gold-plated contacts for high brightness. The contact is a golden reflection of light. False is generally yellow plated, poor in light and reflection, and is generally greenish.
Reed: The authentic ones are darker in color, while the replicas are made of poorer copper and lighter in color.
Enclosure fonts: genuine materials, fonts will be relatively thick and uneven fonts, nails or other hard objects can be removed, and the color is not pure white. The domestically-made imitation OMRON generally uses pad printing, the font is pure white, and it is very light and thin. Now it is found that the imitation goods have artificially irregular fonts. Only two relays are required. You can publish them. The location of irregular fonts on the imitation goods is the same.
Origin: Currently OMRON's MYJ series relays are produced at OMRON's Shenzhen plant; LYJ series relays are produced in Indonesia.
2. PLC disaster area - Mitsubishi's PLC, FX1S and FX1N etc.
Port: View the programming port that internal jack, the original Mitsubishi internal metal plate is gold-plated, non-original mostly silver or titanium and other non-gold. Box: The fake PLC's box is darker than it really is. Tags: Fake PLC packaging label paper is pure white, true PLC packaging label paper is milky white. Strokes: fake PLC on the XOXIX2YOY1Y2 these printed color darker, thicker strokes. Mold: Fake PLC's mold is relatively rough. Label font: The label fonts on the right side of the fake PLC are really different, and the paper is weaker and tends to yellow.
3. Contactor disaster area - ABB
Coil: Open the contactor, the imported coil has the EU code and the original factory code.
Joints: There are generally no joints for counterfeiting. Short-circuited imported products generally use a small copper bar, if you encounter a short line of connection, you are afraid to ask a question mark. Certification: There are a lot of international certification marks on the side of the imported shell, and the weight is heavier than that of domestic ones. You can check online. The domestic code can be found by just hitting ABB's 800 toll free hotline.
Price: Generally 30%~50% more expensive than domestic ones are normal, and there are ABB warehouses in Beijing, Shanghai, and Xiamen. Products that come from Europe generally have some stock there.
4. Module product series - Infineon
Appearance: Especially on the label side, it should be compared with the unlabeled side. Both sides have the same degree of smoothness. Under the light, if there is a lot of horizontal stripes on one side of the label, the module should be polished. of.
Font: Authentic module fonts are clear and free from ink.
Terminals: Trigger terminals and connection terminals. If the trigger terminal has a trace of soldering or the connection terminal has screws, it is undoubtedly a second-hand refurbishment.
Feel: When you touch the label with your fingers, especially the bar code, there will be a noticeable bump, and some fake ones will not. Especially if the module model is marked, if the whole is concave and relatively smooth, it must be a polished module.
Internal: The cover of the FP series module can be opened. By observing the size of the internal chip and the number of aluminum wires at the output end, the specifications of the module can be judged. For example, there are 6 modules of 75A aluminum wires, and 50A of module aluminum wires. There are four.
5. Inverter series disaster area - Delta
Shell: Delta's original authentic shell is milky gray, no impurities on the surface, smooth and not rough. The fakes are somewhat white in color.
Label: logo is clear, black and white, English spelling DELTA.
Origin: original authentic "madeinchina".
Knob: There is a white point on the knob. This is very important. There are no such white spots on many replicas.
Nameplate: There is a bar code on it to identify the authenticity.
Well, as the skills you get yet?
It's not as good as we are with a couple of contrasts to reinforce our intuitive impressions:

At the end will be buyers
