New "TX24A / 25A Series" 1.27mm Pitch High-speed Transmission
Board-to-Board Connector Has Been Developed

TX2425A series 1.27mm Pitch High-speed Transmission
Board-to-Board Connectors supplied by JAE electronics

JAE has developed the new TX24A / 25A Series, a higher-speed version of the popular 1.27mm pitch TX24 / 25 Series board-to-board internal connector used in industrial equipment.

The amount of the data processed in various office automation and communication equipment such as multi-function printers and routers is ever increasing, with internal signaling now supporting DisplayPort1, PCI Express2, and other high-speed transmission.

The TX24A / 25A Series is an 80 contact, 1.27mm pitch, horizontal mating, board-to-board connector with a design that is ideal for high-speed transmission due to the improved electrical characteristics of the upper contacts.

The TX24A / 25A Series also incorporates superior features of the existing TX24 / 25 Series connectors like a strong click feeling, robustness, and high contact reliability. The connector was designed with rack-and-panel mounting in mind, and shares the same mating interface and board-mounting footprint as the existing TX24 / 25 Series. The TX24A /25A can be used as a replacement in the existing connector applications, as well as used in a wide variety of other devices.
