When your equipment sits outdoors or gets hosed down regularly, cheap connectors just give out. The LP16 9-Pin Industrial Waterproof Aviation Plug Solder from Cablein Technology is made for this reality. It combines a metal and plastic housing with 9 solder pins. Rated IP68, it handles 5A at 250V and seals cables from 7 to 9 mm. That keeps your power and signal lines safe from moisture and dirt.

Hybrid Metal and Plastic Housing
We didn't go for a full metal shell here because it adds too much weight to the cable. Instead, this design gives you the impact resistance of metal where it matters, while the plastic keeps it light and easy to route. You also get decent shielding against electrical noise in crowded cabinets.
9-Pin Solder Connection
Nine pins give you plenty of room for a mix of power and signal wires in a single cable. We use a solder design because it provides lower contact resistance than screw terminals. It takes a bit more time to wire up, but the joint stays solid even when machines are vibrating.
IP68 Sealing for 7-9mm Cables
Many connectors leak once you use a thicker wire. Our silicone ring is sized for 7 to 9 mm outer diameters. When you tighten the threaded coupling, it compresses properly to maintain IP68 protection, even if the cable gets pulled.
Threaded Locking
Push-pull connectors can easily disconnect on moving machinery. This model uses a threaded coupling to keep the plug and socket locked together. They stay securely mated until you intentionally unscrew them.

Real-World Applications You Can Count On
Industrial Control Cables
When running control lines between machine modules, the LP16 9-Pin Industrial Waterproof Aviation Plug Solder does the job well. The IP68 seal keeps damp air from ruining your electronics on the factory floor.
Outdoor Lighting Arrays
Rain and temperature swings are just normal conditions for outdoor lighting. With a -40°C to +85°C operating range, this connector keeps power stable from freezing winters to scorching summers.
Food Processing Lines
Washdowns are unavoidable in food plants. Standard plastic plugs get brittle and crack. The hybrid housing on this LP16 handles cleaning chemicals much better, giving you a longer service life.
Marine and Dockside
Salt spray eats away at cheap connectors fast. The sealed design and threaded lock give you solid protection against corrosion on dockside gear.
Automotive Test Rigs
When testing vehicles, you have vibration and moisture everywhere. Solder joints and threaded locks make this connector a reliable choice for temporary test setups.
Before anything leaves our factory, it goes through strict ISO9001:2015 checks. We don't just test the electrical specs; we dunk the connectors in water to confirm the IP68 seal holds at the 7-9mm cable range. We also pull on the solder joints and check the threads. It means the LP16 9-Pin Industrial Waterproof Aviation Plug Solder you get is ready to install without extra fuss.

Q: Can I get this connector with a different number of pins?
A: Yes, we make them in 2, 3, 4, 5, 7, 8, and 9 pin versions. Tell us what your application needs.
Q: Will my cable fit?
A: As long as your cable's outer diameter is between 7 mm and 9 mm, the standard sealing ring will work.
Q: Can I test one before placing a big order?
A: Absolutely. We recommend getting a sample first. You can check the fit and the seal on your actual cable before committing to a full run.
Q: Do I need to ground the metal parts?
A: If your equipment requires shielding or earth continuity, yes, you should ground the metal components.
