I listen to you Steve I have a 15 (+GND) D sub of which I only need 8 pins. All of them will be wired up though. Goodness knows what I will need the others for, but you never know do you? R-

I have never seen or heard of these connectors. What are they normally used for. I can then see what i have been using instead. john

You see them used for connecting peripheral hardware like printers to computers.

I agree John, with a permanent layout there would be little or no need for them. On my ‘fixed’ layout they are used to feed the lift up flap by the door. On t’other layout the boards are designed to be removed from the shed for maintenance so a decent connector is needed on each one. I use five sets on there.

I use them on all portable layouts where cross board connectors are needed.
The ready made D connector leads are not suitable for solenoid point motor operation or where higher then about 1/2 Amp track currents exist, as the wires used in the factory made leads are very thin.

FB, I had a couple of old 1 x metre 25 pin RS232 serial cables and I thought I'll use those. It wasn't until I cut them in half that I saw just how small the internal wires were!

my one piece of advice when soldering D-Sub connectors... always plug them into the opposite socket while soldering... it helps with the heat dissipation away from the plastic, and prevents melting (and thus being a pain to connect).

Not normally an issue when you are adept with an Iron, but while learning, it does save a plug or two!
