LP12 3-Pin Plastic Waterproof Micro Wire Connector
2.3 screw terminals handle 5A at 125V for 0.75-1 mm² wire—no soldering iron needed.
3.IP67 seal locks out water for 5-7mm cables, so a bit of rain or damp air won't cause trouble.
4.Just strip the wire, push it in, and crank the screw down. Done in under a minute.
5.Screw terminals clamp the wire tight, so normal vibration won't shake the connection loose.
6.Got a small sensor box or control relay with no room to spare? This micro connector slips right in.
7.From Cablein Technology—standard versions in stock, with custom pin layouts if your project needs something specific.

LP12 3-Pin Plastic Waterproof Micro Wire Connector——Tiny Connections for Tight, Wet Spaces
Tight spots don't have room for big metal plugs, and soldering irons aren't always an option. The LP12 3-Pin Plastic Waterproof Micro Wire Connector from Cablein Technology gives you a 3-wire hookup with zero heat. You just strip the wire, shove it into the terminal, and crank the screw down tight. That's it. It'll take 5 amps at 125 volts, and the seal handles cables from 5 to 7 mm—so splashes don't get in.
Why Choose Our 3-Pin Plastic Waterproof Micro Wire Connector?
Three-Terminal Block with a Screwdriver
No crimping tools, no soldering iron. Just a screwdriver. You strip the wire, stick it under the screw, and tighten it down. Once it's tight, a bit of shaking or bumping around isn't going to bother it.
All-Plastic Shell Doesn't Corrode
No metal means no rust—so you don't have to worry about it rotting away in damp spots. It's also lighter than a metal plug, so it won't drag down your small wires.
Sealed Against Splashes and Dirt
When you crank the coupling tight, that silicone ring squishes down and seals up. So whether you're hosing the gear off or it's sitting out in the rain, water isn't getting to the contacts.
Built for Small Wires
It handles 0.75 to 1 mm² wire for low-power loads, so it's the wrong choice for big motors but spot-on for compact controls.

Where This 3-Pin Micro Wire Connector Earns Its Keep
Three-Phase Signal Relays
Small relays usually need three wires for signal, neutral, and ground. DIN rail boxes are always cramped, so the tiny plastic body of this connector lets you squeeze it in where a standard metal plug just won't go.
Portable Tool Battery Mods
If you're building or repairing custom battery packs for power tools, 3 pins give you positive, negative, and a thermal sensor line. The screw terminals let you swap a damaged wire without pulling out a soldering iron.
Tiny LED Controller Dimmers
Small RGB LED controllers use three channels for separate color signals. This micro connector handles the 5A load, and the IP67 seal means outdoor garden lighting won't short out in the rain.
Waterproof Sensor junction boxes
Inside small sensor junction boxes, space is at a premium. The LP12 3-Pin Plastic Waterproof Micro Wire Connector gives you a 3-pin waterproof pass-through that doesn't rust, thanks to the all-plastic body.
Small Agricultural Solenoid Valves
Miniature 3-wire solenoid valves on drip irrigation lines sit in damp soil. The plastic housing won't corrode, and the IP67 seal keeps moisture away from the contacts.
Quality Control at Cablein Technology
Every batch gets checked before it ships. We dunk samples in water to prove the IP67 seal holds across the 5-7mm cable range. We also torque the screw terminals to make sure the threads don't strip and test the 1500V withstand rating. If it carries the LP12 3-Pin Plastic Waterproof Micro Wire Connector label, it has passed those checks.
Common Questions
Q: Can I use this for a 3-wire sensor with a shield?
A: The 3 pins are for the signal lines. The plastic body doesn't offer a shield connection. If you need EMI shielding, check our metal-shell models.
Q: How do I wire the pins?
A: Strip about 5mm of insulation, insert the bare wire into the terminal block, and tighten the screw. No special crimping tools are required.
Q: Is the 5A rating enough for a small solenoid valve?
A: Yes, most miniature solenoid valves draw well under 5A. Just check your valve's current draw to be sure.
Q: Will my 6mm cable fit?
A: Yes, the standard sealing ring accommodates cables with an outer diameter between 5mm and 7mm.
