High Contact Reliability with Independent Two-Point Contact Design, 0.5/0.4mm Pitch, 125℃ Heat Resistance
FPC/FFC Connector FH75/FH75M Series for Automotive Applications

FPC/FFC Connector FH75/FH75M 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. In addition, automotive interior space is growing in important and displays have become increasingly larger and higher definition due to the spread of automated driving. Consequently, compact, high pin count connectors that support the required increase in signals are required.

FH75/FH75M Series supports a high temperature of 125℃ due to the enhanced contact material and design. The high FPC/FFC retention force and 2-point contact design provide high contact reliability.
These connectors have passed severe automotive test conditions to ensure safe use in harsh environments, and as a result have been adopted mainly in sensing devices which require high reliability. Furthermore, the FH75M Series has a narrow pitch of only 0.4mm at a high pin count, making it the ideal FPC/FFC connector for in-vehicle applications, especially display connection.

Connectors for Automotive


(1) Heat-resistant up to 125℃. Withstands Automotive Temperatures

The heat-resistant materials and spring used in the contact design minimize deformation due to heat and provides high contact reliability. As a result, FH75/FH75M can be used in a high-temperature environment of 125℃.
We have conducted strict tests required for automotive devices including temperature cycle tests (-40 to +125℃, 1,000 cycles) and heat resistance tests (125℃ for 1,000 hours) and verified that there are no problems.

(2) 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.

Contact design with independent springs improves contact reliability.

■ FPC/FFC High Retention Force

FPC/FFC with tabs on both sides of the mated portion can be used with FH75/FH75M. The tall side-catches securely hold 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.

(3) 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.
