Hey there! When a supplier suddenly has 'excess stock' of a discontinued PLC module at suspiciously low prices, you should definitely be cautious. Here are the key red flags to watch out for:
1. Impossible discounts - If the price seems too good to be true, it probably is. Research shows that 'impossible discounts = fraud' is a major red flag.
2. Lack of authentication data - Genuine suppliers should provide supporting authentication documentation. Counterfeit modules often appear externally identical but lack proper certification.
3. Poor quality labeling - Look for blurry fonts, misspelled words, or strange formatting on the modules. These are classic signs of counterfeit parts.
4. No chain of custody - Ask for documentation showing the parts' journey from the original manufacturer. An unbroken chain of custody reduces counterfeit risk.
5. Supplier verification issues - Check if the supplier is properly verified and has a track record. New or unknown suppliers with 'excess stock' should raise concerns.
Remember, counterfeit PLC modules can cause serious problems like equipment malfunction, costly downtime, and safety issues. Always verify before you buy!
