Delta type N connectors are medium size, 50 Ωimpedance connectors with 5⁄8"-24 threaded coupling. They are best
suited for use with cables in the range of .350" to .450" diameter, but are available for other cables with diameters from
.100" to over 1". Many of our N connectors are available as MIL-PRF-39012 QPL versions, and adapters as
MIL-PRF-55339 versions. These types are listed starting on page 190. Our extensive line of type N receptacles includes
configurations for virtually any packaging requirement, and we can supply any adapter or accessory you need to
complete your system design. Adapters between type N and other series are shown starting on page 176.
As with our other connector series, Delta’s customer-driven design results in N series connectors with practical and unique
features that make your design and assembly process easier. Some of these include:
•Heli-Grip cable connectors for fast, reliable assembly to flexible cable without special tooling.
•One-Step cable connectors for quick, accurate assembly to semi-rigid cable.
•PressMount receptacles (page 85) mount securely in a single round hole, saving space on your components and
reducing your housing fabrication costs.
•Panel receptacles with flange sizes to match the same hole pattern as standard SMA or BNC/TNC connectors, letting
you drill one hole pattern and mount BNC, N, SMA, TNC, or 7/16 series connectors as needed.
•70 Ωimpedance N connectors (see page 89) for matched-impedance applications.
Our N series product line is still growing, so please call if you don’t see what you need.
