M20 2pin T Type 3ways Male Female Waterproof IP68 Connector Power Wire Cable Circular Plastic Connector for Outdoor LED Light
Product Overview
The Three-Port Round Weatherproof Connector is a miniature, environment-resistant round coupling that permits one incoming cable to branch safely toward two outgoing devices while maintaining complete dirt-repelling and liquid-blocking protection. This connector serves as a neat, standards-compliant branching node for outdoor LED luminaires, photovoltaic module strings, sensing elements, small-scale motors, and field-level power taps without requiring circuits to travel back to a central distribution panel.
Key User Advantages
- Instant branching without additional enclosures - transform a single cable route into two energized devices at the installation point
- Reliable IP67/IP68 protection with twin O-rings and threaded collar or molded bushing barrier
- Field-installable or pre-assembled options accommodating various cable diameters and conductors
- Incorrect-connection prevention through keyed inserts for reverse polarity protection
- Industrial-grade gold-plated brass or phosphor bronze alloy contacts
- Extensive temperature range from -40°C to +85°C (with higher temperature variants available)
- Reduced storage requirements by replacing multiple components with a single solution
Main Features
- Round threaded locking ring (M12×1, M16, M20) or twist-lock bayonet mechanism
- T-profile (in-line tap) and Y-profile (evenly divided branch) housing forms available
- Integrated cable strain relief at every opening (withdrawal force ≥ 50 N)
- PA66+GF / PBT body with UV-light resistance and UL94-V0 flammability classification
- Silicone / EPDM sealing rings with compound-filled cavities on pre-assembled variants
- Polarity-marked terminals (L/N/E or 1/2/3) on screw-type products

Competitive Advantages
Compared to traditional solutions, this connector offers significant benefits:
- 70% smaller volume than metallic junction boxes with no corrosion-prone fasteners
- Maintains IP rating versus cable ties and heat-shrink tubing while remaining re-accessible
- Superior water deflection and performance under hose-down conditions compared to rectangular connectors
- Reduces conductor waste and fitting count compared to acquiring multiple cable assemblies
