IP68 Waterproof T-Type Connector 16A 250V 3-Way Circular Power Splitter for Outdoor LED Garden Lighting Branch
Three-Gang Circular Moisture-Resistant Coupler - A compact, weather-defying round interconnect that allows a single inbound cable to diverge safely toward two outbound appliances while preserving particle-excluding and fluid-blocking seals across the entire unit.
Key Benefits
- Immediate splitting without cabinet requirements - deploy extra streetlamps, cameras, or detectors anywhere along a stretch
- Dependable IP67/IP68 protection with O-rings and threaded barriers against precipitation, jet-washing, and dampness
- Job-site attachable or pre-manufactured options accepting 4-10 mm cable diameter and 0.5-2.5 mm² wires
- Wrong-hookup prevention via coded inserts for Hot/Neutral/Ground or signal allocation
- Factory-standard gold-coated brass contacts with touch resistance ≤ 5 mΩ
- Wide temperature range: -40°C to +85°C (up to +105°C variants available)
- Reduces inventory burden by replacing multiple components with one three-way unit

Applications
- Exterior LED lighting: road lamps, patio/frontage/scenic lights, tunnel and bridge illuminators
- Solar and battery systems: photovoltaic string splitting, combiner box secondary supply
- Monitoring and smart city infrastructure: Power-over-Ethernet or DC line distribution
- Manufacturing automation: M12 three-way taps for proximity switches, IO-Link systems
- Marine, camper, and agricultural environments: bilge pump splits, irrigation systems
- Event and concert power provision: temporary outdoor audio/lighting distribution
Competitive Advantages
- 70% smaller footprint than metal junction enclosures
- No rust-vulnerable lid screws or internal moisture buildup
- 5-minute setup compared to 20 minutes for traditional enclosures
- Maintains IP rating while being re-openable and visible for inspection
- Curved profile sheds moisture better than square connectors
- Reduces wire waste and attachment count per split node
