Frequently Asked Questions

Can I order 75 ohm or 50 ohm versions separately?

Yes. Both 50 ohm and 75 ohm variants are available individually. Combined dual-impedance assemblies can also be produced to your specification.

What frequency range does this connector cover?

The standard series covers DC to 3 GHz, making it suitable for HD video, sonar, and broadband data links. Higher-frequency variants up to 6 GHz are available on request.

Is the connector suitable for wet-mate operation?

The standard series is dry-mate. Wet-mate coaxial connectors designed for in-situ subsea mating are available as a separate custom product -- contact us for details.
