Favorite d-sub backshell and solder cup connector combo

[ezalys]

Hey I have to connect a bunch of thermometers to a high end temperature controller, and the connectors on the temperature controller are all db9s. I'm looking a high end, high quality metallized shell that comes with a nice assortment of grommets and a high quality cable clamp, and a matching solder cup male db9 connectors. Does anyone have a favorite combo on their list of parts?

Hi,

    Probably late to your party, but I've used the DB25 size of these for a couple eight-channel audio snakes:

I don't know the temps they can handle, but L-Com is good with info like that.

Good health,  Weogo

I've used so many different types over the years that I can't say for sure which was the best.   The Amphenol 17E-1724-2 is probably the one I see most often and the one I would order if i wanted a plastic cover.   However if given a choice I would go for a diecast back shell like: 17E-1657-09.

I tend towards Amphenol but obviously there are a lot of options for vendors.  The big advantage in my mind when it comes to the dicast solutions is that the metal parts are highly reusable.   The plastic solutions vary a lot, with the snap together or the ones using self taping screws, basically one time solutions.   The bolt together plastic units are more robust and reusable but in my imagination the diecast are a step above.

As for solder cup connectors simply select a better grade of connector.    However in my personal opinion the solder cup DB solutions suck.   If you are at all looking at production quantities get a crimp pin system.   I find soldering DB style connectors to be tedious, beyond that they seem to be prone to failure from poor soldering.   fortunately there are lots of options for crimped style pins for the DB system all the way up to mil spec barreled crimps.   

By the way there is another problem with solder cupped DB connectors and that is that some manufactures use plastics that melt way to easy.  You need to work quickly which sometimes isn't easy when working with multi wire cables.   Off the top of my head I'm not sure who is better with this issue.
