Single-Core Watertight Coaxial Underwater Connector

Description: Single-core watertight coaxial connector for underwater RF and video transmission. Sealed coax penetration for subsea cameras, sensors and sonar.

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.

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.

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.
