Have a look at TE Superseal connectors. Used quite a lot in the automotive sector, and should fit all of your criteria.Ian.
Thanks. I have seen some of them, and even some copies (china I guess... brand MUYI). So far though, I haven't found one I could mount is a simple drilled hole (meaning ROUND). Even if I end up using plastic enclosures, square or oval shaped holes are a pain. And if I go with metal enclosures, no way I'll be able to cut anything but drilled (round) holes.
But I'm on their website now, and will look some more. Thanks again!
