What is a unshielded 3R Cat.6A modular plug?

Unshielded 3R Cat.6A Modular Plug Explained

I. Core Features

• 3R Protection Design:

Harsh Environment Resistance: Designed for outdoor/semi-outdoor scenarios, the outer shell features an added UV-resistant layer (prevents sun damage) and a waterproof gasket (prevents rain penetration), making it more weather-resistant than ordinary plugs.

• Basic Dust and Moisture Protection:

The gasket seals port gaps, preventing dust and moisture from entering the contacts (not IP68, but can withstand light rain under eaves).

• Performance Positioning:

Supports 10Gbps high-speed transmission (within 100 meters), suitable for upgrading outdoor cameras, wireless APs, and other devices to 10Gbps.

II. Structural Analysis

•Reinforced Outer Shell:

The nylon outer shell incorporates carbon black UV-resistant material, preventing cracking and fading even after long-term exposure to sunlight.
The gasket at the tail compresses the cable sheath, providing basic waterproofing (not immersion grade).

•Simple Protection:

No metal shielding layer; relies on physical sealing for moisture and dust protection, costing 50% less than industrial plugs.

•Contact Rust Prevention:

Gold-plated contacts prevent oxidation, adapting to outdoor temperature and humidity variations.

III. Applicable Scenarios

• Outdoor Low-Voltage Boxes:

For connections inside fiber optic boxes and meter boxes in residential areas—moisture-proof and dust-proof, preventing contact corrosion.

• Rooftop Equipment:

Outdoor cameras and AP devices—withstands splashing rain, but not suitable for direct downpours.

• Temporary Networks on Construction Sites:

Wiring in prefabricated construction houses—prevents dust from entering the ports.

IV. Installation Points

• Waterproof Rubber Ring Inspection Item:

Before crimping, ensure the rubber ring is not twisted; otherwise, water may leak in rainy weather.

• Outdoor Cable Compatibility:

Outdoor-grade network cable (PE sheath UV resistant) must be used; ordinary indoor cables are prone to cracking under the sun.

• Contact Protection:

Immediately after plugging and unplugging, cover with dust caps (included) to prevent long-term moisture corrosion.
