The BM54 Series from Hirose Electric are Floating Board-to-Board Connectors that are designed for automotive applications. They have a contact and mounting pitch of 0.4 mm and a mated height of 3 mm. These connectors have an AC/DC voltage rating of 50 V and a current rating of 0.3 A. They have an operating temperature range of -55 to +125°C and can withstand 10 mating/unmating cycles. The BM54 series connectors support PCI-ex Gen4 (16 Gbps) and MIPI D-PHY Ver. 2.1 standards and can be used for in-vehicle applications for front cameras, rear/side cameras, millimeter-wave radar, LiDAR, and other devices that require misalignment absorption of the substrate by small-size floating. They can also be used in devices that require absorption of the substrate misalignment for consumer and industrial equipment.
