(Defacto) standard DC barrel connectors
Karel:
Is there a (defacto) standard or informal list of DC barrel connectors that tells which size
(inner diameter, outer diameter, length) to use for 5, 12, 24V etc.?
If not, what is most common for 5VDC and for 12VDC?
edit: I just found this: https://en.wikipedia.org/wiki/Coaxial_power_connector?useskin=vector#IEC_60130-10
Berni:
The great thing about standards is that there is so many to choose from. :-\
Jeroen3:
Are the sizes supposed to be coded to voltage?

If only! They're not even coded for polarity.
nctnico:
The ones with a 2.1mm or 2.5mm center pin seem to be most common. Just look at the wall-wart / desktop power supplies you can buy from Digikey, Farnell, etc.
