The HARTING multi-coaxial connector system Mini Coax for board-to-backplane RF interconnection includes connectors for press-in technology with 2 to 10 coaxial lines.
The Mini Coax connector range allows transmission of analogue signals in various applications like cellular base transceiver stations repeaters and passenger entertainment systems at radio frequencies up to 2.5 GHz per line at 50 Ohm.
The Mini Coax connector is a multi line RF connector for blind mating of board-to-board, board-to- cable or cable-to-cable applications. The MiniCoax connector is mainly used in both RF (Radio Frequency) and IF (Intermediate Frequency) signal transmission and is specified for a frequency range from DC to 2.5 GHz and beyond. Thanks to its compact size (a 10 coaxial contacts’ connector is as small as a PC's enter key) and excellent crosstalk features, this connector system is ideal for high end equipment for analog signal transmission.
The isolated coaxial lines are implemented in a plastic housing that defines the module size in a metric scale from 1.00, 1.25 and 1.50 SU (SU = System Unit = 25 mm). The Mini Coax connectors are available as straight sockets and right angled plugs. Both types are executed in pressin technology for the PCB (Printed Circuit Board) termination. The straight modules are delivered with an inserted plastic cap that protects the coaxial contacts against dust and dirt, as well as being used as an upper press-in tool. In this way, an easy and safe flat rock process is guaranteed.
The low-profile Mini Coax right angled board connector and matched cable assemblies have the same RF performance as the standard Mini Coax connectors. Their slim interfaces, which provide a board-to-cable solution for the slim cabinet, are suitable for a minimum 15.2 mm slot width. The Mini Coax single-row is another new development with even smaller slot width and higher frequency up to 4.5Ghz.
The coaxial contacts of the connector are single line, as opposed to the standard connector. This delivers enhanced performance, especially in terms of isolation, and is also suitable for slim cabinet applications.
