Four pins in a 16mm shell. All metal. The LP16 4-Pin All-Metal Solder Plug gives you two extra lines over the 2-pin version without changing the mounting footprint — and the zinc alloy housing takes impacts that crack plastic. Solder terminals hold each line tight. IP68 sealing keeps water out at 2 meters for 24 hours. This is the plug you pick when four lines have to reach small gear that gets dropped, kicked, or hosed down.

Two-pin connectors handle simple DC runs. Add a signal line, a ground path, or a second circuit, and you need more contacts. The LP16 4-Pin All-Metal Solder Plug gives you that in the same 16mm shell as our 2-pin version. Pin density goes up; external footprint stays the same. That means it drops into existing brackets and cutouts without redesign.
The all-metal housing is the point here. A plastic-shell 16mm connector cracks if it hits concrete. The zinc alloy version takes the impact and keeps sealing. The trade-off is a few grams of weight — a small tax at this size. Solder terminals mean the connection doesn't depend on a crimp tool being calibrated, and the keyway keeps all four pins going in the right orientation.
IP68 at 2 meters for 24 hours. Every batch gets tested, not every tenth one. That matters because this plug ends up on gear that's genuinely exposed — outdoor camera arrays with dual power and signal lines, industrial sensor clusters, portable test instruments that get dropped on deck, agricultural equipment controls. Places where a plastic connector would crack after a season.
The silicone seal handles the wet side. The metal shell handles the mechanical side. Four pins at 10A each gives you enough headroom for two circuits, or power plus signal, in a shell that fits where larger connectors won't.

Four-line runs in small gear that takes a beating. Outdoor camera arrays with dual power and signal lines. Industrial sensor clusters on vibrating machinery. Portable test instruments that get dropped. Agricultural equipment controls. Marine deck electronics. Anywhere you've got four lines going into small gear that gets banged around and wet — and that's where the LP16 4-Pin All-Metal Solder Plug ends up.
Every batch gets a dielectric test and a waterproof check. Solder joints get pull-tested, not just eyeballed. It costs us time. It saves you callbacks.
The LP16 series carries TUV, CE, and RoHS. We run ISO9001:2015, so material sourcing is consistent and production records are traceable. And the quality system actually gets audited — not just claimed.

Q: Why four pins instead of two?
A: Dual circuits. Power plus signal on one cable, or two independent lines with separate grounds. Same 16mm footprint, just denser inside.
Q: Why all-metal instead of hybrid?
A: Impact resistance. If your gear gets dropped, kicked, or banged against steel — go metal. If it lives in a cabinet, the hybrid version is lighter and cheaper.
Q: What cable size does it take?
A: 1 to 1.5mm² (16 AWG) with a 7 to 9mm outer diameter. Light power and signal class.
Q: Can it stay submerged?
A: Yes. IP68 covers continuous immersion. We test at 2 meters for 24 hours.
