Waterproof Circular Connectors (GX/SP) from China
1 resources tagged with "Aviation Connector"
So-called 'aviation connectors' from China are the GX12, GX16, GX20, and SP21 families of waterproof circular connectors — despite the name, almost none are actually aviation-rated; the term is a market label. What buyers actually need is verified IP67 or IP68 sealing and the right pin count and current rating. The real sourcing risk is a connector marked IP67 that leaks in the field because the supplier never ran an actual ingress test.
When you source GX/SP connectors, treat the 'aviation' label as marketing and focus on the measurable specs — IP rating with a real test, pin count, current per pin, and panel cutout size. The common pitfall is assuming the IP rating is verified; we ask for the ingress test report or run a sample dunk test before trusting it.

FAQ
Are GX and SP 'aviation connectors' actually aviation-grade?
No — it's a market nickname. They're waterproof circular connectors for industrial and outdoor use, not aerospace-qualified parts. Buy them for IP67/IP68 sealing, not for any aviation certification.
How do I verify the IP67/IP68 rating is real?
Ask for the ingress protection test report, or run a submersion test on samples yourself. Many low-cost connectors carry the marking without ever having passed the test.
