With all due respect, I disagree. The term
"Centronics", whatever its
original meaning, refers to a type of
connector. Looking at the Jameco catalog, for
example, the catalog
pictures 14, 24, 36 and 50 contact
male and female connectors, all referred to as
"Centronics". I have
never heard the term "blue ribbon" used
to describe these connectors.
My understanding is that Centronics was the first to use this type of
connector on
its parallel printers, so
when it became the standard type connector the name
stuck.
No, Tony is correct. Just because a name is commonly (mis)used in a
particular way, doesn't mean it's correct, especially in catalogues. This
discussion has come up before in relation to "DB9" connectors etc. A
Centronics connector is a specific size, 36pins. The other sizes (14, 20,
24, 50, etc) are NOT Centronics connectors. The 24-way is sometimes
referred to as an IEEE-488 connector. Does that make all the other sizes
IEEE-488 connectors too?
The common misuse is fairly recent, too. 50-pin conectors in that shape
have been around for a long time, as SCSI connectors, as telco connectors,
and for datacomms. Only in the last 5-8 years have I seen them referred to
as Centronics.
BTW, this type of connector, regardless of the number
of pins, when made
for ribbon cables, is referred to
by Jameco as "IDC Centronics Connector".
So they're misusing the term, that's all. If they'd said
"Centronics-style" that would be different.
