0.4mm Pitch
DF40A Series
The DF40A series is a low-profile, floating panel-to-panel connector with a 0.4mm pitch and a 3.0mm mating height, enabling high-speed data transfer. It supports high-speed transmission standards: MIPI D-PHY (2.5Gbps), PCI Express Gen2 (5Gbps) & 3 (8Gbps), meeting the high-performance requirements of automotive equipment. The floating connector features a shielded frame structure on the outside, making it suitable for robust automotive applications.
