Coax Connectors / Miniature Coax 250 Series
Mini-BNC Plugs & Jacks
The mini-BNC 250 RF connector series from Trompeter was designed specifically for DS3 telco coaxial central office applications to
allow higher interconnect density while preserving the positive characteristics of the Trompeter full size BNC. In fact, the 250 series
provides for higher density of interconnects in a given area.
