I started designing a template sheet to make subminiature connectors and noticed that in the reference libray I was using, components with more than three rows of pins have thir grids offset from 0,0 by between 0.1 mm and 2 mm. I do not know if this is because of my reference library having been distorted (many other components are offset by varying degrees, and angles) or deliberate design.
I won't do the research to find the correct measurements if no one anticipates needing a sub-subminiature connector outside of the common 9,15,25,37 dimensions.
docs.google.com2011.04.05.pdf contains the first four (most common) types for use as a drillling template. Dimensions are described below. Rough sizes, not definitive.
(dimensions are described in inches for consistency, though some components are drawn in mm) pins 9 15 25^ 37 50^ 78*
Pin 0.027 0.027 0.027166667 x x x 0.027166667 x x x x 0.02715625 x x x x x not calculated 0.056 0.056 0.056 0.056 0.112 0.122835 -- -- -- -- -- 0.040945 Drill 0.04 0.04 0.04 0.04 0.04 0.035433
^ is distorted/ some dimensions are not symmetrical same relative to the 0,0 cordinate, original pin spacing may be inconsistent but preserved. There is a pin at x,0. * is clearly asymettrical, did not bother to calculate the pin layout for this one.
