Sometimes three pins aren't enough. Got a machine that needs 10A of power and a few signal lines? That's exactly what the LP16 4-Pin Plastic Waterproof Multi-Pin Solder Plug from Cablein Technology is for. It handles 10A at 400V on 7-9mm cables, and the IP68 seal means rain or a washdown won't kill it.

4 Pins for Power and Signal
Four pins give you room for a 10A power feed plus two extra signal lines. We use solder joints because they offer lower resistance than screw terminals. It takes a few extra minutes to wire, but the connection won't shake loose on vibrating equipment.
All-Plastic Body Keeps It Light
The whole housing is plastic, which means no rust and less weight. It's built for equipment where a metal shell would be overkill, but you still get solid mechanical protection.
IP68 Sealing for 7-9mm Cables
The silicone ring is sized for thicker cables. Crank the coupling down tight, and it compresses into a solid seal. It handles temporary submersion, not just rain, so outdoor gear and wet factory floors are no problem.
Handles 10A at 400V
It’s rated for 10A at 400V, and it takes 1 to 1.5 mm² wire. Because it's soldered, you get better contact than screw terminals—it won't heat up even when you're pulling the full 10 amps.

Motor Plus Two Sensors
Got a machine that needs 10A of power and a couple of sensors? This 4-pin plug lets you run all of them through a single cable. The solder joints won't crack when the motor vibrates, and the IP68 seal keeps the moisture out.
Outdoor LED and Signage Feeds
Running 10A out to a floodlight or signage array with extra control lines? It takes the current without getting hot. And since it's all plastic, you won't have to worry about it rusting. Plus, the IP68 seal means rain won't be an issue.
Field Generator Hookups
Generators often need a quick, waterproof 4-pin link for power and control. The 7-9mm cable range fits standard heavy-duty leads, and soldered joints won't shake loose.
Marine and Dockside Gear
Salt spray just destroys cheap connectors. That’s why the all-plastic body on this one matters—it won't corrode. And with the IP68 seal, water can't get in to reach the contacts.
Food Processing Washdown Areas
Daily hose-downs are normal in food plants. The LP16 4-Pin Plastic Waterproof Multi-Pin Solder Plug shrugs off moisture, and there's no metal to rust.
Before anything leaves our factory, it goes through strict ISO9001:2015 checks. We dunk them in water to confirm the IP68 seal holds at the 7-9mm cable range. We test the 10A/400V rating and 2000V withstand voltage. We also pull on the solder joints to make sure they hold. It means the LP16 4-Pin Plastic Waterproof Multi-Pin Solder Plug you receive is ready for the field.

Q: Can I get this connector with more pins?
A: Yes, we make them in 2, 3, 4, 5, 7, 8, and 9 pin versions. Tell us what your application needs.
Q: Is this for high-power loads?
A: Yes, the 4-pin version is rated at 10A/400V, which is plenty for small motors, lights, and mixed power-signal runs.
Q: Will my cable fit?
A: The standard sealing ring fits 7 to 9 mm cables. If you're using a different size, let us know and we can match the right ring.
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.
