Five wires usually mean a mix of power and control signals. The LP16 5-Pin Plastic Waterproof Circular Wire Solder Plug from Cablein Technology handles that with a 5A at 400V rating, a 7-9mm cable fit, and an IP68 seal. So rain, washdowns, and heavy vibration don't stand a chance.

5 Pins for Mixed Power and Signal
Five pins give you enough channels for a small motor plus a few 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 5A at 400V
Rated at 5A and 400V, it takes 0.5mm² wire. Solder joints give you lower resistance, so the connection stays cool even under a full load.

Motor Plus Signal Lines
When a machine needs a power feed and several control lines, this 5-pin plug runs them all in one cable. Solder joints hold up when the motor vibrates, and the IP68 seal keeps moisture out.
Outdoor LED and Signage Feeds
Running power and control lines out to a floodlight or signage array? This plug carries the current without heating up. The plastic body won't rust, and the IP68 seal handles rain.
Field Generator Hookups
Generators often need a quick, waterproof 5-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 kills cheap connectors. The all-plastic body resists corrosion, and the IP68 seal stops water from reaching the contacts.
Food Processing Washdown Areas
Daily hose-downs are normal in food plants. The LP16 5-Pin Plastic Waterproof Circular Wire 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 5A/400V rating and 2000V withstand voltage. We also pull on the solder joints to make sure they hold. It means the LP16 5-Pin Plastic Waterproof Circular Wire 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: No. The 5-pin version is rated at 5A/400V, which is ideal for signal and control circuits. If you need higher current, check out our 2-pin or 3-pin models.
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.
