Voltage rating of keyboard cable?

[terryS]

A question:
Have one of those older style keyboard cables in hand; this one is
NOS
(i.e. brand new, old stock).
It has a 5 pin (large) DIN plug at one end.
Anybody got any idea of the maximum 'voltage' rating; of the wire and
the plug?
Not worried about the 'current' (amperes) rating; only the maximum
safe voltage.
Any info appreciated. TIA.

Typically, it's the wire in the cable that is the voltage limit; the
connector
isn't rated for high currents, but will take hundreds of volts
safely. The
wire, usually intended for flexibility (sometimes as a coiled cordset)
is
not likely to be marked.
So, examples of this kind of cable (flexible multiconductor) offer
some guidance,
and 150 to 300V is the low end of the range in cable catalogs.
Ultrafine
wire like for earbuds is the only thing commercially available that's
lower.

Current rating IS important, though; if one were to connect to an AC
socket,
the protective circuit breaker is set at 15A to 20A, the wire is
unsafe unless
it reaches that limit.

most data cabling is rated for 100V or more
if you look closely the details may be imprinted on the cable.

new old stock (thay keyboard's gotta be more than 15 years old) may bave
leached out plasticisers and be less flexible than new stock.

Not worried about the 'current' (amperes) rating; only the maximum
safe voltage.
Any info appreciated. TIA.

Why does it matter to you?

It sounds like you want to use the cable for something else, and likely
there are better alternatives, but we can't know that until we know
whether this is idle curiosity or you actually want to use the cable
for high voltage.

And why does it matter to _you_ what the OP wants to use it for?
