BNC COAXIAL CONNECTORS
The Connex BNC connectors are made to a high quality level. Medium size coaxial
connectors with bayonet lock. 50 ohm impedance for applications up to 4 GHz and 75 ohm
impedance up to 2 GHz.
75 OHM SERIES
Within the internationally standardized BNC mating face dimensions, a perfect 75 ohm
characteristic impedance cannot be realized. However, at frequencies up to 1000 MHz, the
small impedance deviation is negligible for practical applications. Connex true
75 ohm connectors with a typical VSWR reading of 1.06:1 at 2000 MHz are identified by
an asterisk following the part number.
All 75 ohm BNC connectors and 50 ohm BNC connectors are intermateable without
restrictions.
Note: Silverplated bodies are available by adding “S” to end of part number. Nexcote (white
bronze) plating with no nickel under body or center contact is available by adding
“NEX” to end of part number.
