Your sample is basically a unicase version of DIN.

Designal is not an exact match, but seemingly had the same design brief when it was created:

Thanks for that marcox. I think I had pretty much come to a similar conclusion myself. Now that I look again, there unmodified DIN elsewhere on the page, but the 'Q' in the unicase had thrown me before.

I came across Designal. A nice face, altogether. I'm ideally looking for something similar but it's crucial that it has regular, italic, bold, and bold italic fonts so itself that's a no-go. Any other suggestions along the same lines would be welcome, otherwise I'll keep scouring or just lump it and find a different angle to work from!

Amazingly enough "din unicase" (in quotes, as a phrase) yielded zero results in a google search. Now that's a marketing opportunity some enterprising type designer should seize!
