B04008010L Standard Balun - BNC(M) to Krone IDC, 2-45Mbit/s, 75/120Ω
Standard Balun BNC Male to Krone IDC, 75/120Ω 2-45 Mbit/s
The B04008010L Standard Balun connects a twisted pair cable to a BNC(M) coaxial connector. This allows the use of smaller lower cost twisted twisted pair cables and consequently saves installation time, space and cost.
The internal Balun matches the characteristic impedance of the 75Ω coaxial connection to the 120Ω twisted pair cable thus minimising losses. It is fully shielded and designed to connect 2-45 Mbit/s (E1/E2/E3) data streams while exceeding the ITU’s G.703 transmission standard.
The B04008010L is terminated with a standard Krone tool. We recommend punching the wires down with the Balun placed in 12mm hole drilled in wood to avoid damaging the connector interface components.
It is one member of a family of Standard Baluns that extends to all coaxial connector types found in network use. Please contact us for special types not listed on this website.
