Are D-Sub connectors suitable for carrying multiple lines of
low-current 230V AC? The idea is to connect up to 10 individually
controlled loads over a 50-foot multi-core cable. The wires are
rated for the voltage. Current levels are sub-100mA.
The cable is to be used only 2 or 3 times a year for a couple of
days on each occasion, to be dismantled and stored in between
each use. On three previous occasions, I used a bundle of twin
wires with individual male plugs at one end and a box with a row
of females at the other, but I'd like to make the whole thing
less bulky and fiddly. (As I've occasionally mentioned in s.e.d.,
I'm in a place where it's not a simple matter of choosing a
suitable connector from an online list and ordering it).
I don't know if there's a universal standard voltage rating for
D-Subs. I've seen one manufacturer's specs of 1000Megs minimum at
500VDC and dielectric strength of 1000V AC for 1 minute. To keep
things simple, forget about mechanical reliability. I have good
soldering experience and could cover each soldered pin with
heatshrink, clamp the wires and provide strain relief. I'm sure
D-Sub connectors will be fine initially, but I'm wondering about
the long-term since they are normally used at much lower
voltages.
