B13008010 Standard Balun - BNC(M) to Krone IDC, 2-8Mbit/s, 75/120Ω

ACE Website B13008010 v2

The B13008010 Standard Balun connects a twisted pair cable via a 3 pole Krone Insulation Displacement Connector (IDC) to a BNC(M) coaxial connector. The internal Balun matches the  impedance of the 75Ω coaxial connection to the 120Ω twisted pair cable to minimize losses. It is designed to connect 2-8 Mbit/s (E1/E2) data streams.

Twisted pair cables with conductor diameters from 0.4 to 0.65mm are easily terminated with a standard Krone tool. The resulting installation gives the user a faster, smaller and lower cost connectivity solution.

  • BNC(M) screw attach coaxial connector to 3 pole Krone IDC
  • 75/120Ω impedance transformation
  • twisted pair wire sizes 0.4 to 0.65mm
  • 2-8MBit/s transmission rate. Exceeds G.703 requirements.
  • low return (<33dB) and insertion (<0.16dB) losses for E1 data
  • Gold plated pin and connector body
