Waterproof power connectors
Sealed plugs and sockets for harnesses that see rain, wash-down or condensation: e-bike and battery leads, charging ports, outdoor LED and equipment wiring. Prices are per piece, EXW Yueqing, in US dollars.
Contact layouts
The range covers 2+1+7, 2+1+5, 2+2, 2+3, 2+5, 2+6, 3+10 and 8-pin layouts. In a 2+1+7 set the middle number is a dedicated earth contact, which is why a 2+1+7 part is not interchangeable with a 2+8 part even though both carry eight signal-side positions. Check the layout before comparing two families on price.
Ratings as published
Where the source listing states a rating it appears on the product page: 5 A at 5–220 V on the DX-DY-1350AGM and DX-DY-F717AGM, 1.5 A at 500 V on the DX-XH-B208AGM. Several sealed parts carry no current or voltage figure on the listing at all, and those pages say so rather than filling the gap with an assumption.
Where the seal actually comes from
The seal is the locking collar plus the panel gasket, so the panel cut-out and the collar thread decide whether the assembly stays watertight — more than the housing material does. If the application is safety-related, ask for the ingress test report for the exact plug-and-socket pair you intend to use.
