For semi-rigid cables Receptacles connectors
BNC connectors are a lightweight connector widely used in computer networks, test and instrumentation, telecommunications and broadcast industries. The quick disconnect bayonet coupling, small size, and low cost are key features. Cable termination styles available include crimp/crimp, one-piece sure twist, traditional solder/clamp styles as well as field service terminations requiring no special tools. BNC connectors are available both with 50ohm and 75ohm impedance for applications where impendence matching is important. Typically, the 75ohm BNC is used in video and telecommunication applications.

Application:
Antenna, Automotive, Base Station, Cable Modem, Computers/LAN, Instrumentation, Medical Equipment, Radio, Telecommunication, Test and Measurement, Video System
