BNC Series |
|
|
|
|
BNC is the most popular coaxial connector. The special bayonet design ensures the user an easy mating/unmating connection.
The working frequency is up to 4 GHz for 50 Ohm characteristic impedance.
All 50 Ohm BNC connectors (standard) and 75 Ohm (add "-75" after part number) BNC connectors are intermateable.
The application of BNC connectors are wide, such as monitor, LAN, telecommunication devices and test equipment.
