Terminal Block- What is pitch???

[j0563]

I am looking at these PCB mount terminal blocks- .25 pitch, .325 pitch, .375 pitch.... what does that mean? What is "pitch" referring to?

The distance between the pins.

A standard dual inline IC socket is 2 breadboard holes 0.1 (inch) pitch, and 4 breadboard holes (0.3 (inch)) across.

So it is the distance between hole centres on your PCB.

The space between your legs.

More precisely, the gap between the pin centres.

That link has an error and should be 9.53mm.
Always read Manuf's Data Sheet.

A standard dual inline IC socket is 0.1 (inch) pitch, and 0.4 (inch) across.

Tsk, tsk....

Leave it to engineers to ignore a simple and understandable word like spacing and change it to pitch.

Pitch is more precise. Spacing raises the question - is that between the pins (not including the thickness of the pins) or, the space from centre to centre of the pins (i.e. pitch).

Thanks for the great help everyone- much appreciated!

Quite right BCJ.

Perhaps.. maybe leave it non-engineers to misunderstand a definition?
- just kidding Lefty, I reverted to 'student' mode there.
