Built by YXY — waterproof connector manufacturer since 2002 · 东莞工厂
Built for boats, buoys, aquaculture cages and offshore wind — where every mating has to survive salt spray, constant vibration and prolonged submersion. YXY circular and waterproof RJ45 assemblies keep power and data sealed from deck to seabed, from −40 °C winter storms to tropical sun.
On-deck connectors die from chloride corrosion, on-engine they shake loose, below waterline they leak. YXY marine builds use nickel-plated brass and zinc-alloy shells, gold-plated copper contacts and silicone O-ring seals with factory potting — validated before shipment, not just claimed.
海雾全天候沉积氯化物。裸锌或薄镀层数周内就会点蚀，接触件氧化导致电阻上升、接头发热。
Wave slam, diesel harmonics and crew tugging at cables. Push-pull connectors walk out; plastic threads strip. Offshore wind technicians mate turbine sensors weekly.
Buoys dunk at high tide, cages sit at 2–10 m, decks get hosed daily. Capillary wicking along copper strands floods junction boxes if the seal is only on the shell.
All factory-terminated and 100% continuity plus Hi-Pot tested, with IP spot-checked per lot. Mix-and-match 2–7 pins, PVC / PUR / TPU jackets, 0.3–30 m lengths, custom overmold colors and laser marking.
PA66 body with nickel-plated brass coupling, screw-lock, IP68 mated. The workhorse for deck power, buoy beacons and cage sensors.
Heavy zinc-alloy shell with 12 µm nickel plating, IP67/IP68, 2–12 pin. Built for helm consoles, winch power and turbine cabinets.
IP68 panel-mount bulkhead plus inline coupler, shielded, toolless T568A/B. Radar, NMEA backbones, 4G routers and pier-side SCADA.
Every marine lot ships with a batch card: salt-spray, IPX8, continuity and Hi-Pot. These are the gates your buyer or class surveyor will audit — ask for the full PDF with your quote, no extra charge.
| 测试 | 标准 | YXY 成效（典型值） | 在甲板上的实际意义 |
|---|---|---|---|

Pass — no ingress; insulation over 1,000 MΩ at 500 VDC after immersion | Buoy battery box dunked at spring high tide — electronics stay dry, same seal survives daily deck wash |
| Vibration & Shock | IEC 60068-2-6 / -27 10–55 Hz / 1.5 mm，30 g 冲击 |
通过 — 1 µs 内无瞬断；螺纹锁紧扭矩保持率 90% 以上 | Diesel engine room and offshore wind nacelle — no flicker on sensor power |
| 插拔耐久性 | IEC 60512-9a — 2,000 cycles | ΔR under 3 mΩ; retention force over 80% of initial | Aquaculture crew mate DO probes weekly for cleaning — year 3, same trunk |
| Temp. Cycling & Humidity | −40 to +85 °C, 100 cycles 93% RH / 40 °C / 56 days |
No cracking, no seal set; insulation over 500 MΩ | 一月结霜、八月甲板温度达 45 °C 的浮标工况 — 无冷凝失效 |
Values are typical production means; every lot is 100% continuity plus Hi-Pot with AQL IP spot-check. Field record: 60 × SP16 5-pin and an RJ45 gateway at a Fujian shrimp farm, 3 m depth, 18 months continuous — zero ingress returns, only barnacle cleaning at harvest. Stainless-steel SP21/YM20 and acrylic strand-block potting are available for permanent submersion beyond 10 m.
