## Description

If you need to add a panel-mount connection for Ethernet, but don't have the time or ability to cut a custom oval or square hole, this **RJ-45 Ethernet Round Panel Mount Extension Cable** is the easiest and fastest way to panel-ify your existing Ethernet kit. It's 30mm in diameter (the required cutout size is 25mm), so you can drill a hole in your wood, plastic or metal with a common hole-saw or bit (25mm), no special shapes or filing required. Un-screw the included plastic nut (the part with flat sections shown in the photos), insert the plug and re-attach. Ta-da! Now you have an Ethernet jack with a Ethernet plug!

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 an Ethernet port to your project enclosure! Adafruit like this adapter in particular for its solid body and 'forgiving' plastic lip that hides the drill hole.

## Technical Details

- Cable length (excluding connectors): about 23cm
- Panel mount Ethernet 8P socket with Ethernet 8P plug at cable end. Straight-through extension
