The 5678 Series are connectors mainly used to connect printed circuit boards in parallel directions for applications such as FA computers, OA equipment and medical equipment, in which high reliability and high-speed transmission are required. High reliability is also required for the connectors which connect mission-critical components in such equipment. The 5678 Series feature a pitch of 0.8mm and a stacking height between 10.0 and 19.0mm, with 20 to 120 positions. These connectors, also featuring high-speed transmission and a floating structure based on Kyocera Connector Products’ proprietary product concept, are the most suitable stacking type connectors for connection with sub boards to expand functions. They enable high-speed serial data communication of 5.0Gbps compliant with PCI Express 2.0. The floating structure absorbs misalignments in mounting the connector on the printed circuit board and losses caused from installation of the connected printed circuit, by moving ±0.4mm in the X and Y directions respectively. Such structure allows multiple low-pin-count connectors to be mounted on the printed circuit board and does not require crowded wiring to high-pin-count connectors. Thus, there is more flexibility in the wiring layout and the connectors can be positioned in each circuit with the shortest path, enabling effective use of the mounting area. In addition, these connectors have achieved an optimum structure for preventing quality deterioration of data transmission signals.
