The M16T Waterproof Plug is an M16-threaded (≈16 mm coupling nut), T-type/branch-capable circular waterproof connector used across outdoor LED, solar auxiliary, and light industrial power distribution applications. The "T" designation refers to the T-shaped/1-in-2-out branch body configuration, also known as an M16 T-splitter.
Built with an M16×1.0 threaded lock featuring silicone O-ring face seal and rear cable gland, it delivers IP67 as standard (IP68 optional) and carries 10 A/300 V AC-DC on 2/3-pin power configurations, 8 A on 4-pin, and 5 A on 7/8-pin models, with 2+4 hybrid (power+signal) options available.

vs M12 A-code plug: +150% current capacity (10 A vs 4 A), T-branch option, larger cable OD compatibility
vs M20 inline coupler: 30% smaller footprint, lower cost, sufficient for LED-fixture and 24 VDC auxiliary runs
vs junction box + PG glands: M16T T-body functions as sealed junction box - reusable, keyed, 70% faster installation
vs generic DC barrel T-tap: Threaded M16 lock with O-ring provides superior vibration and weather resistance
