Hirose Electric D.FL75 Series 75Ω Micro Coaxial Connector

Low-profile 12G SDI connector featuring a space-saving design

The Hirose Electric D.FL75 Series micro coaxial connector was developed in response to the 12G-SDI standard. The D.FL75 improves board design freedom and reduces design time for internal wiring in applications such as broadcasting and video equipment.

The compact D.FL75 is a 75 Ohm, 4K/UHG transmission coaxial connector enabling internal wiring of equipment. The internal wiring is performed from the back of a BNC adapter attached to the panel with a coaxial cable, eliminating the need for signal routing on the board.

In addition to reducing the space needed for signal wiring, the space-saving 4mm x 4mm board connector area allows for a more flexible arrangement of electronic components. Since the panel and the board can be designed completely separate of each other, not only is the influence of design change minimized, the board can also be used with other panels. Separating the manufacturing and the assembly sites allows flexibility in both design and manufacturing.
