BNC B/H Jack, Front Mount Crimp Type (IP67)
Cable: RG174/U, RG188/U, RG316/U, B7805A,URM95 and more….


  • Computers/LANs
  • Instrumentation
  • Test and Measurement
  • Medical Equipment
  • Broadcast (75 ohm)

  • BNC connectors with a 50 ohm nominal impedance are designed for use in telecommunication, data communication and test and instrumentation equipment. BNC connectors with a 75 ohm nominal impedance are designed for broadcast, video and other applications which require impedance matched performance. Both 50 ohm and 75 ohm BNC connectors are intermateable.
  • Interface according to IEC 169-8, MIL-C-39012 BNC, MIL-STD-348B
 Special Notice  

• The specification is listed below for information.  All dimensions are fully complied with Military requirements.
  S-Conn provides commercial grade connectors, and environmental requirements we can test in-house is Salt
  Spray test at the moment.
• For electrical and mechanical test, we can cover most of it in-house.  Please refer to our Profile, Product Range,
  QA and QC to see what equipment we have.

• Any questions, please feel free to contact our QA department.
