I-PEX FPC/FFC Connectors

I-PEX^® EVAFLEX^® FPC/FFC Connectors have an auto-locking feature that makes them more robust and durable than traditional FPC/FFC Connectors. EVAFLEX Connectors include EMI shielding and support for high-data-rate transmission. The unique lock feature on these connectors make them extremely operator friendly.
I-PEX^® MINIFLEX FPC/FFC Connectors, commonly referred to as ZIFs or LIFs, offer very low cost options with pin pitch ranges from 0.5 mm down to one of the world’s smallest at 0.175 mm. Connector height profiles range from a robust 2.5 mm down to one of the industry’s lowest at just 0.55 mm. These connectors have an additional mechanical lock option with FPC cut out lock feature, perfect for applications that require higher FPC retention force and for adding FPC retention force for smaller pin counts.

Why select I-PEX Auto-Lock FFC connectors?

1 ) Auto-Lock Mechanism

Auto-lock-GIF ◆　One-step operation helps improve productivity and is also designed for robotic automation.
◆　Auto-lock structure reliably holds the notched FFC, creating excellent retention force against pulling and vibration.
◆　You can hear and feel the connector click when mating, which will prevent half-mating insertion.

2 ) High-Speed Transmission

High-transmission-GIF High-speed transmission is made possible by improved shield and contact design.
◆　4+Gbps : EVAFLEX^® 5-SE-GHT, EVAFLEX^® 5-SE-GVT
◆　8+Gbps : EVAFLEX^® 5-VS
◆　10+Gbps : EVAFLEX^® 5-HD
◆　16+Gbps : EVAFLEX^® 5

3 ) High Temperature Resistance

Why select I-PEX FPC connectors?

1 ) Mechanical Lock Creates High Retention Force

dw5 High retention force is created by the lock contacts. These contacts are on both side walls of the connector and are designed to catch and hold the designated cut out area of the FPC. The mechanical lock ensures approximately 1.7 times higher resistance compared to our 0.3 mm pitch, 19 pin count connectors without a mechanical lock. This connector is not only ideal for high vibration environments, but it is also suitable for applications that require high FPC retention. FPC retention force comparison chart is here.

2 ) Hold Down to Improve Strength of Side Wall and Prevent Actuator Drop-off

MFX_Actuator(HD) Have you ever faced actuator drop-off during assembly? Certain I-PEX FPC/FFC connectors were developed with improved side wall hold down features that help the actuator from dropping off.
