Have you looked at the 25pin RS-232 plugs and sockets that were the universal computer connector a decade or three ago.

Too big I'm afraid.

Too big as well. All 18 individual cables have to go into 1 braided sleeve.

As I suggested in post 4, or did you not read it?

Yes, unfortunately not suitable.

I have nothing to add I'm afraid, but I do have a level of intrigue to satisfy...
What's it for?
Lighting for a 1:10 scale Offroad RC car.
Is space really as limited as you've implied - e.g. could you not use two 9-pin ones? ... and does it really have to be all that 'waterproof'?
Kind Regards, John

Well it needs to control 9 leds, so yes, it needs a min of 18 pins. IP55 rating would suffice, and there is less than 1 inch of space available (length) I think a MIL connector will suffice, seen some that look potentials, but needless to say, expensive.
Why does 9 LEDs need 18 pins - would not 10 be adequate (1 common plus one for each LED)? Anyway, what I was asking was whether there was not any other space, anywhere, given that a 1:10 car is hardly a 'matchbox' model!
... and do you really need IP55 - after all, that's more than would be required in, say, a bathroom.

Hmm, hadn't thought of that, so maybe only 10 pins required. Yes, it goes in the sea. (shallow part) and whilst 1:10 is not tiny, even to make space for the light controller, the normal setup has to be modified to make space.
I did. But I used a proper and more specific term. There are many what you call “D-type connectors.”
Indeed, as I said. In fact, do you really have 9 LEDs which all need to be independently controlled? On a full-sized car, virtually all of the lights come on in pairs (or even triplets). If your '9' include any pairs (or triplets) which always come on together, then you could reduce the number of pins even further.
Fair enough - that's rather more dramatically 'off-road' than I had envisaged
