Adafruit RJ-50 (10P10C) Round Panel Mount Adapter Plug

If you need to add a panel-mount connection for telephone-interfacing projects but don't have the time or ability to cut a custom oval or square hole, this RJ-50 Panel Mount Plug is the easiest and fastest way to panel-ify your existing phone kit.

It's about 30mm in diameter, allowing you to drill a hole in wood, plastic, or metal with a common hole saw or bit; no special shapes or filing are required. Unscrew the plastic nut, insert the plug, and re-attach. Now you have a pass-through RJ-50 jack.

Note that this is not compatible with RJ-45 Ethernet Jacks or plugs; these are bigger and have more contacts, 10 instead of 8! It's designed to easily attach to a panel up to 16mm thick (or 0.625") or as thin as a few mm.

Perfect for adding a port to your project enclosure, this adapter is preferred for its solid body and forgiving plastic lip that hides the drill hole.
