B04083070 Mini Balun - SMB(M), Bulkhead Mount to IDC, 0.5-0.65 wire size, 2-34Mbit/s, 75/120Ω

AC&E MB SMB(M) Snap

Mini Balun SMB Male Bulkhead to suit 0.5-0.65mm STP/UTP 75/120Ω 2-34 Mbit/s

The B04083070 Mini Balun connects a twisted pair cable to a SMB 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 2-34 Mbit/s (E1/E2/E3) data streams while exceeding the ITU’s G.703 transmission standard.

The B04083070 features AC&E’s IDC termination which does not require special tools. For details on the Mini Balun termination procedure click here.

It is one member of a family of Mini Baluns that extends to all coaxial connector types found in network use.

Mini Baluns are ideal in applications where size and space are limited.
