I've never tried this and I don't personally have a stax, but using the diagrams in the mouser catalog, the pins look like they're the right ones for the stax connector. I couldn't find dimensions, though, so you can't be entirely sure
box mount (sorta like the neutrik 1/4" locking jacks):
PT02A-10-98P (plug)
PT02A-10-98S (socket)
~$12 ea socket
jam nut (pretty much panel mount)
PT07A-10-98P (plug)
PT07A-10-98S (socket)
~$20 ea socket
There's an "environmental series" type, probably bigger and more robust, and a wall mount type, but I'm not entirely sure how either one mounts. They start with PT00A- and PT00E- for the part number, respectively. There's an overview (no detailed datasheets I could find) on these amphenol-industrial.com
