When you've got a machine that needs one power line and a half-dozen control signals, you don't want to run seven separate cables. The LP16 7 Pin Plastic IP68 Waterproof Solder Connector from Cablein Technology pulls all of that into one plug. It's rated for 5A at 250V on 0.5mm² wire, and the IP68 seal means you can put it just about anywhere.

One Plug, Seven Wires
Seven pins is the sweet spot. You get enough room for a small motor and a bunch of sensor lines without buying a massive connector. We use solder cups because they don't loosen up. Yeah, it takes a few minutes with a soldering iron to wire it up, but once it's done, vibration won't back the terminals out like it does with screw clamps.
No Rust, No Worries
The whole shell is plastic. That means if it's sitting out in the rain or getting hosed down at the end of a shift, it's not going to rust or corrode. It's also way lighter than the metal-shell stuff, so it won't put a bunch of strain on your cable.
It's Actually Waterproof
The threaded ring squeezes a thick silicone O-ring tight against the housing. If you're running 7-9mm cable, it seals down solid. You can submerge it in a puddle for a bit and the contacts stay bone dry.
Bolts Right to the Panel
Since this is the flange mount, you just drill four holes, bolt the socket to your enclosure, and you've got a sealed bulkhead pass-through. It keeps your wiring clean and keeps the water out of your cabinet.

Stage and Event Lighting
Lighting trusses shake like crazy when they get moved. If you use cheap connectors, the pins cut out. The LP16 7 Pin Plastic IP68 Waterproof Solder Connector doesn't have that problem. Solder joints hold tight, so the lights stay on during the whole show.
Security Cameras and Poles
When you're running power and video lines up a pole, you need a connection that won't let rain in. Bolt the flange to the camera box, solder your wires, and forget about it.
Conveyor Belts and Packaging Lines
Conveyors vibrate all day. Screw terminals slowly walk out and you get a dead machine. Solder doesn't do that. Run your sensors through this plug and you won't have to send a guy out with a screwdriver every week.
Control Cabinets
Mounting this on a cabinet door or wall is easy. It gives you a clean, waterproof feed-through so the stuff inside the box stays dry.
We don't just slap these together and ship them. Every LP16 7 Pin Plastic IP68 Waterproof Solder Connector gets a 100% pressure test before it goes in the box. We're ISO 9001:2015 certified, and we pull-test the solder joints to make sure they don't break. If it can't handle 1500V, we throw it out.

Q: How hard is it to solder?
A: Not hard, but it's not a push-in connector. You gotta strip the wire, tin the cup, and make a clean joint. Do it once and do it right.
Q: Can I put a motor and some signals on the same plug?
A: Yeah, but watch the amps. It's rated for 5A total. If your motor pulls a lot of juice, keep the signal wires separate.
Q: What if I mess up the soldering?
A: You can heat it back up and pull the wire out. Just clean the cup real good before you try again, or the new solder won't stick right.
Q: Will the plastic crack in the winter?
A: No. It's rated down to -40°C. It'll freeze, but it won't crack.
