M16 3 Way T Connector 2 4 Pin Male Female Aviation Plug IP67 IP68 Waterproof Electrical Wire Connector
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.
- High Current Capacity: 10 A/300 V in compact 16-mm shell - covers 12/24/48 VDC LED strings and 230 VAC applications
- Integrated T-Type Branch: 1-in-2-out overmolded T-body eliminates need for separate junction boxes
- Superior Protection: IP67 standard / IP68 optional with silicone O-ring, threaded M16 nut, and rear gland
- Flexible Installation: Field solder, screw terminal, or pre-molded cable options available
- Premium Contacts: Gold-plated brass contacts with ≤10 mΩ resistance
- Keyed Polarization: Prevents L/N/G reverse on DC LED installations
- Optimal Size: 150% more current than M12 A-code, 30% smaller than M20 connectors
- Coupling: M16 × 1.0 threaded nut
- Body Forms: Inline cable plug-socket pair, T-type 1-in-2-out, Y-type, front/rear panel flange socket
- Pin Configurations: 2/3/4/5/6(2+4)/7/8/9 pins
- Termination Options: Solder cup, screw clamp, IDC, or pre-molded cable
- Cable Gland: Rear strain relief for 4.5-6.5 mm & 6.5-9.0 mm cable OD
- Materials: Copper alloy contacts with gold flash; PA66+GF insert and shell
- Sealing: Silicone O-rings + rear grommet; optional protective caps
