@Andrewier....Thanks for that, very well put, I'd forgotten about VGAs.  I guess there  is some sense to it.   Are you sure about DB-31 - I remember seeing a high denisty plug the sdame size as a DB-25 but (like a VGA) with 3 rows of pins, but there would have been a lot more than 31 there....

@David Ashton

I am not sure if we are talking about the same (or my bad English is tricking me), but... let it go:

If the matter is DB x DE connector designations, the first letter (D) is for 'D' type (or trapezoidal), second - A,B...E is for shell size and the number, for the number of pins, of course. For example, we can have DB25 and DB31 - same shell size but different number of pins. The same for the - once ubiquitous - DE9 (PC serial port) and DE15 (aka VGA) .

Got them all- I guess I must be an instrument guy. LOL.

I'm not convinced you can't use type B below 0°C but it has a nasty hook around there where it reverses slope, so a given mV can map to more than one temperature, and nobody that I've seen has bothered to measure the mV below 0°C (the only reason to use such a nasty Pt-Rh thermocouple is if you have to go up to very high temperatures (>1500°C)).

Thanks as always Martin.  Got 3/5 - came short on the language one and no 5.  Should have known better on this one as I have come across it before.  Silly idea though, if they have a unique letter, what's the point of putting the number?
