LP20 3-Pin Metal-Plastic Waterproof Screw Connector
2.Rated for a beefy 20A at 500V, handling 2.5-4 mm² wire for heavy-duty power runs.
3.The metal shell takes a beating and sheds heat, while the plastic body keeps the whole thing light.
4.IP67 sealing locks out water for 8-12mm cables, surviving rain and daily washdowns.
5.Once that screw terminal bites down, normal machine vibration won't rattle it loose.
6.Operates from -40°C to +80°C, so it holds up in freezing plants or boiling factory floors.
7.From Cablein Technology—standard models in stock, with custom pin layouts available if you need them.

LP20 3-Pin Metal-Plastic Waterproof Screw Connector——No Soldering Iron Required – Solid Power Connections for Wet Conditions
Wiring a 3-phase machine and don't want to drag a soldering iron out to the site? The LP20 3-Pin Metal-Plastic Waterproof Screw Connector from Cablein Technology is built exactly for this. You just strip the wire, shove it into the terminal, and crank the screw down. It handles a solid 20A at 500V and seals cables from 8 to 12 mm, so rain and washdowns don't stand a chance.
Why Choose Our 3-Pin Metal-Plastic Waterproof Screw Connector?
Screw Terminals for On-Site Speed
No crimping tools, no heat guns. Just a screwdriver. If you're wiring up multiple machines on site, this saves you a ton of time. And once that screw is tight, the terminal grips the wire hard enough that normal vibration won't shake it loose.
Metal and Plastic Work Together
The metal parts take the physical abuse and soak up heat. The plastic keeps the whole thing light and easy to snake through tight spaces. And because there's metal in the mix, it naturally blocks electrical noise—a lifesaver in a packed control cabinet.
IP67 Sealing for 8-12mm Cables
We sized the silicone ring specifically for thick cables. Crank the connector down tight, and it squishes into a solid seal. Hose it off or leave it in the rain—water isn't getting inside.
Handles Serious Power
Rated at 20A and 500V, this isn't a toy. It takes 2.5-4 mm² wire, so you can push heavy power through it without worrying about it melting or overheating.

Real-World Applications for This Screw Connector
3-Phase Motor Connections
Three pins line up perfectly for basic 3-phase setups. Instead of soldering inside a tight motor junction box, you just screw the wires down. The IP67 seal keeps moisture off the terminals.
Temporary Power on Job Sites
When you're setting up temporary lighting or power runs, you don't want to solder in the dirt. The screw terminals let you hook up 8-12mm cables quickly and take them apart just as fast when the job is done.
Vibrating Pump Systems
Pumps shake. A lot. While the screw terminal holds the wire tight, the threaded coupling locks the plug and socket together so they don't rattle apart.
Washdown Enclosures
If your control cabinet gets hosed down, you need a connector that won't let water in. The metal body takes the abuse, and the tight silicone seal keeps the moisture out of your 20A power lines.
Strict Quality Checks at Cablein Technology
Every batch gets tested before it leaves the factory. We don't just trust the specs; we physically dunk these connectors in water to prove the IP67 seal holds up on an 8-12mm cable. We also torque the screw terminals to make sure they don't strip under pressure, and we run 2500V through them to check the insulation. That's why the LP20 3-Pin Metal-Plastic Waterproof Screw Connector you receive is ready to work.
Buyer Questions We Actually Get Asked
Q: Can I reuse this connector if I mess up the wiring?
A: Yes, that's the beauty of screw terminals. Just unscrew the terminal, pull the wire out, and try again. No cutting or re-soldering needed.
Q: Does the metal housing affect the current rating?
A: No, it actually helps. The metal body dissipates heat better than plastic, which is great for a 20A load. It also blocks electrical interference.
Q: What kind of wire works best with the screw terminals?
A: Stranded wire between 2.5 and 4 mm² (14-12AWG) works perfectly. The screw clamps down firmly on the strands without cutting them.
Q: Is it hard to get the IP67 seal right?
A: Not at all. Just make sure your cable outer diameter is between 8 and 12 mm. Tighten the coupling firmly, and the silicone ring does the rest.
