Structure reference & engineering support
Use the catalog structure families to shortlist the installation path first, then confirm model fit by drawing dimensions and final mating condition.
| Connector family | Best used when | Check first | Typical input | Next step |
|---|---|---|---|---|
| Removable Flange-Mount Connectors | A replaceable panel or fixture RF interface is required | Gender, flange pattern, mounting geometry | Panel drawing, mating side, socket bore / pin dimension | Request flange-mount match → |
| Air Feedthrough Connectors | RF path must pass through a wall, enclosure or bulkhead | Flange style, ØD1, length, installation space | Wall thickness, protrusion length, bore condition | Request feedthrough match → |
| Threaded Input Connectors | Compact rear-thread or threaded panel input is required | Bore / pin dimensions, rear diameter, thread spec | Rear thread, panel thickness, retention method | Request threaded input match → |
| Vertical Mount Adapter Connectors | A compact vertical RF transition is required | Mounting pattern, contact geometry, mechanical fit | Mounted geometry, interface direction, available height | Request vertical adapter match → |
| End Launch Connectors | Board-edge RF launch transition is required | Board interface dimensions, contact geometry, launch details | PCB stack-up, launch geometry, grounding pattern | Request end launch match → |
Common selection questions
What is a 1.85mm RF connector?
A 1.85mm RF connector, also called a V connector, is a precision 50 Ω coaxial interface designed for high-frequency operation up to 67 GHz.
Is 1.85mm compatible with 2.4mm connectors?
The 1.85mm interface is mechanically compatible with 2.4mm connectors under correct mating conditions. Transitions to SMA or 2.92mm usually require an RF adapter.
How do I choose between solderless PCB, end launch, flange-mount and feedthrough structures?
Choose by installation path: reusable PCB validation, board-edge launch, replaceable panel or fixture interface, wall or enclosure feedthrough, or rear-threaded panel input.
What information is required for a 1.85mm connector quote?
Please provide target frequency, connector family, interface gender, flange or thread details, PCB stack-up, panel or fixture drawing, available installation space and quantity.
