World's smallest width floating connector released

Hirose has developed a board-to-board connector that combines floating functionality and miniature size to meet automotive specifications. The BM54 Series takes compact design further, delivering the world's smallest width class for its category. The space-saving automotive connector features a small form factor, a 0.4mm pitch, and a stacking height of 3mm to 4.5mm.

Ideal for PCBs with multiple connector sets, the connector series offers a wide floating range of ±0.4mm in XY direction. By absorbing board misalignment errors, floating simplifies assembly and enhances assembly work efficiency. A two-point contact design ensures high contact reliability and rugged performance in harsh automotive conditions.

The series has a heat resistance of 125C, a requirement for in-vehicle and industrial equipment. It also supports PCI-ex Gen4 (16Gbps) and MIPI D-PHY Ver. 2.1, which is ideal for automotive front cameras, rear/side cameras, displays, millimetre wave radar, and LiDAR systems.
