Three-way Round Waterproof Connector - Circular LED Backlight IP68 Power Cable Connect
Product Overview
The Three-Way Round Waterproof Connector (also called 3-way T-type/Y-type circular splitter, 3-port sealed junction connector) is a compact, IP-rated circular interconnect that enables one incoming cable to branch safely into two outgoing devices while maintaining dust-tight and water-sealed protection.
Available in generic M20/M16/LP16 style 3-pin round body or M12 A-coded 3/4/5-pin T/Y splitter configurations for various industrial applications.
Key Benefits
- One-tap branching without panel requirements - easily add second devices mid-span
- True IP67/IP68 sealing with dual O-ring protection
- Field-wireable or pre-molded assembly options
- Anti-miswire keying prevents reversed polarity
- Industrial-grade gold-flash brass or phosphor bronze contacts
- Wide operating temperature range: -40°C to +85°C
- Cost-effective solution replacing multiple components
