So is nylon. But nylon is hydroscopic, and thus not well suited for electronics applications.

I do prefer ABS-PC or ASA for a lot of my more-adverse condition cases. They're much more heat resilient, and chemical/UV resistant in ASA's case.

Well, a great many connectors (even, or rather, especially industrial ones) are made from PA6 or 66 with some glass fiber fill; including the actual contact carriers (if they are a separate part). FR4 is somewhat hygroscopic as well; moisture expansion causes real problems for some applications. Never heard of issues with PA connectors.
