Backplane connectors, also known as board-to-board connectors, are connectors which are designed to connect separate printed circuit board (PCB) assemblies together without cable, enabling them to communicate with each other. The main types of backplane connectors are hard metric, standard and advanced. Among these, the HM2R30PA5108N9LF is a hard metric connector.

Specifically, this hard metric connector belongs to the FMOD series from the Japanese company Hirose, which appreciates them for their reliability, competitive pricing and that the metal and plastic components are joined by Hirose’s robust and advanced locking mechanisms. The FMOD series offers the most comprehensive 2.00mm (.079”) and 2.54mm (.100”) pitch hard metric connector for space saving designs.

Application Field

The HM2R30PA5108N9LF is an ideal solution for closed or open chassis systems, mid-sized backplanes and mezzanine boards, where power and high speed timing requirements can often be met. Some of its other applications include factory automation, automotive control, computer, consumer electronics, express server and other applications.

Working Principle

The HM2R30PA5108N9LF uses a two-piece shrouded construction to provide precision mating and an affordable solution for high-speed motherboards. It has a 2.54mm (.100") pitch with 30 differential signal pairs and two power contacts, with a mating cycle of 500 and 3A (amp) current rating per contact pair.

The contact design includes an ultra-precise ground plane to reduce crosstalk and strengthen circuit uniformity, while the inter-stage insulation ensures reliable contact during mating and unmating. At the same time, the improved guide posts ensure accurate mating and support the extreme mechanical stability of the connectors.

Combined with a robust locking mechanism, the HM2R30PA5108N9LF guarantees a reliable interconnection between the multiple printed circuit boards of an application, improving the performance of the whole application.
