Terminal Block Plug-gable 4 Pins connectors 5.08 Pitch

[Kiriakos GR]

I did the mistake to join Aliexpress again, and now my brain gets again overloaded, due the poor product descriptions and the poorly written full of mistakes part codes.

I did find the connector that I need for the Waveshare to TTL converter and from another source.
This one using descriptions as KF2EDGK+KF2EDGRK

The female alone this is listed as KF2EDGK

I wasted over two hours so to decode everything, so to order the appropriate parts.
Finally I did decide not buying a single connector, but rather get them in pairs, so to use them and in to other projects.
Attached all the information's that someone will need, so to not get wrong parts.

Note regarding electrical specifications.
The manufacturer mention at the datasheet, lower voltage and current limits for UL certification.
And higher voltage and current limits for IEC certification.

I would accept both, but regarding Max Current [Amperes], I would consider as master compass, the electrical limits of 2.5 mm wire (12 AWG), that is 9.3A
When 9.3A this is considered as Max, by dividing this tree times, we get closer to safe constant current limit = 3.1A 

Another good practice, never plug or unplug these connectors under load.

This is an interesting connector, but for special industrial applications.

This seems designed for mixed connections of lines transferring data along of lines for electrical power, an all-in-one solution.
