If its got pins sticking out its a plug so 1 & 2 are P##\PL##.
The rest are sockets S##\SK## (with possibly the exception of #6) as something is inserted into the pins.

IMO calling things a "jack" is misguided, its historical and does not match the plug.
You have a plug and a socket that the plug - plugs into.
Jack is a little lad that went up a hill with his girlfriend Jill. :)

That multi connector is awkward so I'd go off what the majority is - socket.

In the case where the connector has a dual sex, J is used more often.
 
I've seen EE engineers use J for every connector whether it's Male or Female.
 
J is far more popular than P.

What about this connector, would you suggest using J? or P? designator?
 

 
Also, I took a look at what designators are Agilent and Keithley using in their hi-end products. As you can see, they avoid P? and use J? instead.

Ok, thank you. Can you please provide any examples (part numbers) where you would use X? designator?

For example, Wago and Phoenix is using X? designator for all their terminal blocks. So they are doing it wrong then...

You are correct.
 
J = 1, 2 & 8
 
P = all the rest
 
X = Socket and 99.9% of all sockets are female. I don't know of any socket plugs but there might be one, so I didn't put 100%.

Tom, I know that, but it does not make thing very clear to me.
Also,
X = Socket
and hence
XP - Female socket

Tom, so you would use J? for [1], [2] and [8] and P? for all the rest? You would not use X? designator?

I have checked PCB designs from well know companies as TI and Analog, I have also checked provided libraries by connector manufacturers and they all were using different designators for the same type of components. If such big players cannot get it right it is likely not that obvious.

J = Jack (Female)
P = Plug (Male)

Could anyone please specify what are the correct designators for the following parts?



Some would use J? for all those parts, because they are the least-movable parts of a connector. However, some use, for example, JP? for [1], X? for [2], P? for [3], XP? for [5] and TB? for [7].
