The way I learned it was that the 'D' refers to the shape, the 'B' to the
shell size, and the number to the maximal pin count. The spacing is not
.050" however. It seems to me that it's larger than 0.10" andnot less,
except in the high-density versions like the DE15.

Belden Calls them all D-Subminiature connectors either
Plugs or Sockets
(Jacks) in 9, 15, 25, and 37 pins. Metal Head shells or thermoplastic.
Having .050" centered conductors.
DSP009 is 9 pin plug
DSJ009 is 9 position jack (socket)
Were there Standards, or was this left to Mfg part numbering scheme??
Molex, Amphenol, Thomas & Betts, Ansley? Mil Spec?

Thank %deity there's somebody else out there
who actually knows what a
'DB' connector is!. I sometimes think I'm fighting a losing battle
against the people who insist there's a DB9 :-)
How large would the pins be, or how far apart if there WERE a DB9?
Or what about a DB25 serial port cable that only has pins 1-8 and 20?
Could we call THAT a DB9? :-)
