Small devices often get stuck with connectors that are too bulky to fit. The LP12 4-Pin Plastic Waterproof Small Round Connector from Cablein Technology gives you a 4-pin wiring solution in a tiny all-plastic package. It handles 5A at 125V and seals 5-7mm cables with an IP67 rating, so a bit of moisture won't cause trouble.

4 Pins in a Tiny Round Shell
Four pins give you enough channels for a small motor or a mix of signal and power 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
No metal means no rust and less weight dragging on your wiring. It's built for smaller devices where a bulky metal shell would be overkill.
IP67 Sealing for 5-7mm Cables
The silicone ring is sized for slim cables. Tighten the connector down, and it squishes into a solid seal. A bit of rain or washdown won't get inside.
Handles 5A at 125V
Rated at 5A and 125V, it takes 0.75-1 mm² wire. It's made for small loads, not big motors, which is exactly what compact devices need.

Small Sensor Enclosures
When your sensor box has almost no room to spare, a full-size connector won't fit. The LP12 slips into tight spots, and the 4 pins let you run a couple of signal lines plus a power line in one cable.
Portable Lighting and Fixtures
Small LED lights and portable fixtures don't have room for big connectors. That's why this plastic one is handy—it doesn't weigh the fixture down. And with the IP67 seal, getting caught in the rain isn't going to ruin the connection.
Battery Packs and Small Chargers
Small chargers and battery packs often need just a few wires. This plug handles the 5A load without taking up space.
Waterproof junction boxes
Inside sealed enclosures, you don't need a bulky metal shell. The LP12 gives you a waterproof pass-through that's easy to route in tight boxes.
Garden and Drip Irrigation Controls
Small irrigation controllers sit outside in the wet all day. At least the plastic body won't rust on you. And because it's IP67 sealed, moisture stays away from the contacts.
Before anything leaves our factory, it goes through strict ISO9001:2015 checks. We dunk them in water to confirm the IP67 seal holds at the 5-7mm cable range. We test the 5A/125V rating and 1500V withstand voltage. We also pull on the solder joints to make sure they hold. It means the LP12 4-Pin Plastic Waterproof Small Round Connector you receive is ready for the field.

Q: Can I get this connector with a different number of pins?
A: Yes, we make them in 2, 3, 4, 5, 6, 7, and 8 pin versions. Tell us what your application needs.
Q: Is this for high-power loads?
A: No. The 4-pin version is rated at 5A/125V, which is ideal for small devices and light loads. If you need higher current, check out our larger LP16 or LP20 models.
Q: Will my cable fit?
A: The standard sealing ring is sized for 5 to 7 mm cables. If you're using a different cable 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.
