The single-core watertight coaxial connector is a threaded RF pair on a flexible blue-jacket cable: one center contact, a threaded knurled coupling, and a watertight gland at each end. It is the straightforward RF pass-through for camera links, modems and timing signals where only one coaxial channel is needed.
Product Highlights
- Single coaxial channel: one matched pin / socket RF contact — nothing you do not need.
- Threaded knurled coupling: the large knurled ring seats and locks the pair hand-tight, with positive detent at full engagement.
- Flexible blue jacket: the cable bends tightly and stays visible against dark housings and sediment.
- Watertight at both ends: molded glands at each connector keep water out of the braid-to-pin transition.
Key Specifications
| Contact arrangement | 1 coaxial contact (socket end + pin end) |
| Contact plating | Gold-plated center contact |
| Coupling | Threaded knurled ring, hand-tight |
| Cable | Flexible blue-jacket coaxial cable |
| Sealing | Molded watertight glands at both connectors |
| Characteristic impedance | On request — matched to your cable |
| Rated depth | Per datasheet |
| Cable length | To order |
Structure & Sealing
Each end carries a machined coupling body over the cable; a molded gland bonds jacket to shell so the braid transition stays dry. The jack’s socket contact is protected inside the coupling; the plug’s center pin engages as the knurled ring is threaded home, seating the face seal at full engagement.

Packaging & Delivery
Each connector is shipped in an ESD-safe bag with a protective cap on the mating face, packed in a foam-lined carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
What impedance is this connector?
It is built matched to the selected cable — tell us your cable type and we will confirm.
Can I order a specific length?
Yes, cable assemblies are cut and terminated to your length.
Is the coupling rated for repeated matings?
Yes, the threaded coupling is designed for service cycles; contact ratings are in the datasheet.
Do you supply just the connector pair without cable?
Connector-only supply is possible; most customers take the terminated assembly.
