I-PEX Launches CABLINE(R)-UMF, a 0.4 mm Pitch FPC Connector with Mechanical Lock

I-PEX Corporation, a leading manufacturer of connectors, has developed “CABLINE(R)-UMF,” an FPC connector optimized for internal connections in information and communication devices. Sales are scheduled to commence in March 2026. This new connector is an addition to the “CABLINE(R)” series, known for its high-speed transmission capabilities and for holding a significant market share in fine coaxial/twinaxial connectors for notebook PC display panel connections, according to market data.

“CABLINE(R)-UMF” is a vertical mating type FPC connector with a 0.4 mm pitch, featuring a mechanical lock and a maximum mating height of 2.35 mm. It supports high-speed transmission at 40 Gbps/lane PAM3 and incorporates ZenShield(R) for robust EMC countermeasures. By applying the structure and characteristics of the “CABLINE(R)” series, known for its high-speed transmission, to FPC connections, this new product aims to enhance design flexibility in information and communication equipment.

Background of Development

The market for information and communication devices, including notebook PCs, has seen a continuous trend towards faster internal transmission speeds and component miniaturization. This trend presents challenges such as reducing transmission loss with increasing data speeds and addressing interference issues with antenna frequency bands in IoT devices, necessitating effective noise countermeasures for electronic components.

Furthermore, the miniaturization of communication devices has led to tighter space constraints internally. While fine coaxial cables have traditionally been adopted for high-speed transmission in applications like display panel connections, there is a growing demand for transmitting high-speed signals using lower-profile FPCs.

I-PEX has contributed to achieving high-speed transmission connections within information and communication devices through the development of the “CABLINE(R)-UM” fine coaxial connector (0.4 mm pitch, vertical mating type), which incorporates ZenShield(R) for 360-degree EMC shielding. Building on this expertise, “CABLINE(R)-UMF” was developed as a connector capable of utilizing “CABLINE(R)-UM” for shielded FPC connections, further increasing product design flexibility for customers.
