Create a clean, weather-resistant Ethernet connection through your controller or enclosure wall with this IP68 waterproof RJ45 CAT6 M20 cable gland coupler. Also commonly referred to as an RJ45 bulkhead coupler or panel-mount Ethernet feedthrough, it provides a sealed female RJ45 connection on both sides of the enclosure wall without a permanently attached cable.
Designed for pixel controllers, remote receiver boxes, holiday lighting systems, and other outdoor electronics, the coupler mounts through a standard M20 panel opening. Connect your own internal Ethernet patch cord to the inside port, then connect an external Ethernet cable to the weatherproof outside port whenever needed.
Because there is no fixed internal pigtail, you can select the exact patch-cable length, style, and routing that best fits your enclosure. The included tethered protective cap covers the exterior port when it is not connected.
Prefer a connector with a built-in internal cable? See our IP68 Waterproof RJ45 CAT6 M20 Cable Gland with Shielded Pigtail , available with 200mm or 300mm internal cable lengths.
Why Choose the No-Cable Coupler?
- Choose Your Own Internal Cable — Use the exact cable length needed for your enclosure instead of working around a permanently attached pigtail.
- Cleaner Internal Routing — Ideal for builds that already use custom-length patch cords or carefully planned cable paths.
- Easy Cable Replacement — Replace the internal or external Ethernet cable independently without replacing the panel-mount connector.
- Flexible Cable Compatibility — Works with CAT5e, CAT6, and CAT6A patch cords, including shielded, flat, colored, and outdoor-rated cables.
- Service Port Capability — Keep the exterior port capped until configuration, troubleshooting, or network access is required.
Simple Panel-Mount Installation
Install the coupler through a standard M20 enclosure opening, position the included sealing gasket against the panel, and secure the connector with the threaded retaining nut. Connect your internal patch cable to the rear RJ45 port and use the exterior port for your incoming Ethernet connection.
For maximum protection, the connector should be correctly installed, fully tightened, and either coupled to its matching waterproof cable housing or covered with the protective cap.
