Field wiring takes a beating from moisture and constant movement, and standard plastic connectors just don't hold up. That's where the LP16 9-Pin Metal Shell Waterproof Circular Connector Solder from Cablein Technology comes in. It wraps 9 solder pins in a solid metal shell, rated IP68 for 5A at 250V. Since the seal handles 7 to 9 mm cables, you get a tight fit that keeps water out.

Full Metal Shell
This isn't a plastic body with a metal ring. Since the whole body is solid metal, it won't shatter when dropped. It also stands up to heat way better than plastic. Plus, that metal shell naturally blocks EMI interference—which is exactly what you need in a cabinet packed with drives and inverters.
9-Pin Solder Termination
Nine pins give you room for mixed power and signal runs. We use solder joints because they offer lower contact resistance than screw terminals. It takes a few extra minutes to wire, but the connection won't shake loose when the machine is running.
IP68 Sealing for 7-9mm Cables
Thick cables often break the seal on cheaper connectors. The silicone ring is built to fit 7 to 9 mm cables exactly. You just tighten the coupling and it squishes down to make a tight seal. Even if it's pouring rain or you're hitting it with a pressure washer, nothing gets inside.
Threaded Locking
Push-pull plugs have a bad habit of working themselves loose when machinery starts to shake. That's exactly why we went with a threaded lock on this one—the plug and socket stay locked tight until someone actually twists them apart.

Real-World Applications You Can Count On
Industrial Control Cables
When running control lines between machine modules, the LP16 9-Pin Metal Shell Waterproof Circular Connector Solder does the job well. The metal shell and IP68 seal keep moisture and interference out 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. Plastic plugs get brittle and crack over time. The metal housing on this LP16 handles cleaning chemicals and physical abuse much better.
Marine and Dockside
Salt spray destroys cheap connectors fast. The full metal body and sealed design give you solid protection against corrosion on dockside gear and marine electronics.
Automotive Test Rigs
Vibration and moisture are everywhere in vehicle testing. 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 Metal Shell Waterproof Circular Connector 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 housing?
A: If your equipment requires shielding or earth continuity, yes, you should ground the metal shell.
