Dsub empty pin spots
Probably a stupid question - if you only have 5 pins in the connector, do you install all the other pins? I don?t recall ever seeing one that didn?t have all the pins installed...

Watching this one with interest. I've never installed unused pins in the connector, and can't really come up with a compelling reason to do so. Eager to hear from others though.

I only install the needed pins. Do not know why filling empty holes would be advantageous.

I am an amateur at this wiring business. I potted the rear of the socket with some electrical liquid tape to seal the connection. Perhaps overkill in my case. |
From a professional avionics guy, there are 2 reasons you may fill the empty slots. 1-some connectors are water tight and they are required for that reason. Not usually applicable to GA. 2- sometimes it?s a great way to have spare pins when you are in a bind.

Only if you enjoy paying for things you don't need or use. :)

The outer shell of the Dsub connectors is what "keys" the pins to reach their location, so additional pins do nothing to ensure a connection on an adjacent pin. Ergo, no, dont fill them.
But it doesnt hurt anything if you insist on doing so. FWIW, I have 9 pin dsubs for my AP servos - only 3 pins in each..... |

https://www.supercheapauto.com.au/p/...ml/340189.html Thanks for the replies - I also can’t think of a good reason but wasn’t certain. Sometimes there’s an obscure reason. It got me thinking when I couldn’t recall ever seeking a dsub on anything that wasn’t full. |
Some folks might be used to seeing a pin in every hole becasue they have ben looking at solder-on connectors, not crimped on pins. Some harness-makers use the soldered connectors becasue they can be a lot cheaper than individual pins.
I have used crimped pins for decades, and only fill the holes I am using - I understand that if its a water-tight connection, you might do differently, but we just dont run in to those in most of our applications. I refrain from potting the connector becasue it makes it impossible to troubleshoot or modify later if you have to pull an individual pin - might as well use solder connectors in that case! Paul |
How would you get them back out again, unless you've crimped them to a short pigtail of wire?
Seems completely unnecessary. |
