High Contact Reliability with Independent Two-Point Contact Design, 0.5mm Pitch, 125℃ Heat Resistance
FPC/FFC Connector FH75 Series for Automotive Applications

FPC/FFC Connector FH75 Series for Automotive Applications

In recent years, many automobiles have been equipped with cameras, radars, LiDAR, and other devices to enable advanced driving support systems such as lane departure prevention and automatic emergency braking. These electronic devices are often placed in harsh environments such as near the engine room, which is subject to high temperatures and mechanical vibration. The connectors used in the devices must have high performance.

FH75 Series supports a high temperature of 125℃ due to the enhanced contact material and design. Also, high contact reliability is achieved with the high FPC/FFC retention force and two-point contact design. This FPC/FFC connector is ideal for automotive devices because it meets the severe test conditions of the industry and ensures high reliability in harsh environments.


(1) High Contact Reliability

■ Independent Two-Point Contact Design
The two-point independent spring contact design reduces contact failure. For example, if a contact failure occurs due to dust intrusion on one contact, the other contact will not be affected and maintain a secure connection. This ensures high contact reliability.

Independent Two-Point Contact Design

■ FPC/FFC High Retention Force
FPC/FFC with tabs on both sides of the mated portion can be used with FH75. The tall-side catches securely holds the FPC/FFC tabs. Retention force is higher than the competitor’s products and it can be used safely even in an environment affected by vibration.

FPC/FFC High Retention Force

(2) Incomplete Mating Prevention

One of the causes of contact failure is incomplete mating of the FPC/FFC. The tabbed FPC/FFC used in FH75 allows visible inspection of the insertion status from the notched portion of the actuator to prevent incomplete mating, the cause of contact failure.

(3) Heat-resistant up to 125°C. Withstands Automotive Temperatures

The heat-resistant materials and spring used in the contact design minimize displacement due to heat and provides high contact reliability. As a result, FH75 can be used in a high-temperature environment of 125℃.
We have conducted strict tests required for automotive devices including temperature cycle tests (-55 to +125℃, 1,000 cycles) and heat resistance tests(125℃ for 1,000 hours) and verified that there are no problems.
