Hirose Electric Co., Ltd. has claimed one of the industry’s smallest back-flip FPC connectors for automotive and other harsh environment applications. The FH79 back-flip connector series offers a 40% reduction in width compared to standard 0.5-mm pitch connectors.

The FPC connector features a low-profile of 1.2 mm and 0.3-mm pitch (0.6-mm mounting pitch). It uses a dual-contact system (top and bottom contacts) and a staggered contact array design to maximize space efficiency and to reduce the connector footprint.

The high-density FH79 Series is heat resistant up to 125℃, making it suited for harsh environment applications, including automotive. The operating temperature range is -55°C to 125°C. Other key specifications include a rated current of 0.3 A, rated voltage of 50 V, and contact resistance of 70.0 mΩ maximum.

The back-flip design provides high contact reliability, which prevents the actuator opening with upward FPC routing, Hirose said.

Here are the highlights:

The FH79 connector supports high-speed transmission eDP ver1.3 and MIPI D-PHY ver2.1 standards, supporting the digitization of automotive, construction, and agricultural equipment. Applications include automotive entertainment, robotics/factory automation, LiDAR, and sensing cameras.

“The implementation of digitization and feature-rich systems in automotive, construction and agricultural vehicles has raised demand for space-saving wiring solutions,” said Pete Lais, assistant vice president of product management, Hirose Electric Americas, in a statement. “The FH79 Series not only contributes to miniaturization, but also enhances board design flexibility and simplifies assembly.”

The FH79 Series FPC connector is currently available with 61 positions. Versions with 11, 21, 31, 41, and 51 positions are under development.
