Hey guys,
this is a rather academic question because a few tens of microns don't
matter much with those old clunkers, but still this got me puzzled:
Looking at datasheets of D-SUB Connectores from different manufacturers,
I find three different inter-pin distances along the rows:
ERNI: 2.75mm
Harting: 2.74mm for 9 and 15 pin connectors, 2.76 for the others.
Deltron: 2.74mm
FCT: 2.74mm
The inter-row distance seems to be consistently 2.84mm.
All of course are supposed to be according to the same DIN/ISO standard.
Then there is the "US" and the "European" footprint, but I think the
difference is the distance between the PCB holes and the front panel
plane for the angled connectors.
I wonder if it is really true that the 9/15 pin plugs have an
ever-so-slightly different pitch than the others. Who comes up with
ideas like that?
