The plugs are different to the color of the seals of which hardly from a specialized dealer. They are just as stiff - no wonder with protection class IP67 - and the stakes sometimes do not lock, was fortunate that I have additionally soldered for crimping. So I was able to pull out the cable at least again without losing the use of the plug. A locking of the insert is imperative, otherwise you push during mating of plug and socket only use back, but makes no decent contact.
Conclusion:
These plugs were a good choice, so 5 stars!
