Very popular sans-serif font

Hi everyone,
I'm Federico, and i'm new to this wonderful site, so sorry for my inexperience (and for my english).
I'd like to know the name of this font, which I saw many times, but never find out information about it.
So if anyone could help, i'd be very grateful!

P.s.: This time i found it on a flyer(?) image via FFFFOUND! (



:D Thank you very much Jan!!

There’s an kinda upgraded version of this original DIN typeface called
FF DIN (available from fontshop). It has lots of weights and even italics.

Oh, that's perfect.. it's excactly what I was looking for!!
Thanks again.
