Mini-BNC Connectors

Mini-BNC Connectors

The Mini BNC connector series offers the high performance and wide compatibility of the original Amphenol 75 ohm BNCs. However, the Mini-BNC has a higher connector density, allowing for 40% more interconnects in the same area.

The Mini BNC series expands on the SMB and SMZ series, providing a positive locking bayonet system, in contrast to the SMB and SMZ push-on mating. In addition, the Mini BNC is specifically designed to be a drop-in replacement and used with Telco and broadband applications.

The Mini BNC is compatible with standard field installer crimp tooling and strip dimensions.

Features and Benefits
  • Crimp ferrule and contact design compatible with standard tooling
  • Same footprint on the jack side, making the Mini BNC a drop-in replacement for most high-density applications using SMB or SMZ jacks
  • 75 ohm performance for 3G video
  • Bayonet locking coupling mechanism
  • Compact version of standard BNC
  • Antennas
  • Medical Equipment
  • Automotive (GPS)
  • Computers/LANs
  • Military/Aerospace
  • Base Stations
  • Cable Modems
  • Instrumentation
  • Network Analyzers
  • Telecommunications
