Backplane connectors specifically refer to the so-called “backplane” or “system bus” connectors. They are used for connecting various components in a chassis-based system - such as a computer or peripheral device. In an electronic system, the backplane connectors provide the physical connection between the components that make up the system and provide the pathways for all data and power to transfer between them. One of the types of backplane connector is Hard Metric, which is also known as “HM2P”.

HM2P80PDA341N9 is an example of a Hard Metric connector. It is a combination of a circular connector, which is often referred to as a “Hard Metric Mini-Fit” connector, and an electro-mechanical 36-pin connector, known as the Mechanical FPC Interlock (MFI) connector. This combination allows the HM2P80PDA341N9 connector to provide good electrical performance as well as a mechanical interlock for reliable connection. The connector is typically used in embedded backplane applications.

Application Field and Working Principle

The HM2P80PDA341N9 is designed for use in compact application areas where high data rates and reliability are required, specifically in embedded backplane applications. It has broad application potential, including Computer Motherboards, Low-Profile Modules, and Hard Metric backplane systems. The connector can also be used for Power Distribution. Additionally, the combination of features between Hard Metric and the MFI connector can be advantageous in many applications, providing a high performance, connection solution.

The working principle of the HM2P80PDA341N9 is relatively simple. The circular Hard Metric or HM2P contacts of the connector are arrayed in a specific pattern, which is a polarity-free design that allows for correct mating regardless of the orientation of the connector. The connector also features the Mechanical FPC interlock which is keyed to guarantee that the connector is only mated correctly. The connection is then made through a series of contacts, connecting the electronic components involved. The connector is rated for a maximum of 80amps and 10mm stacking. This allows for high speed data transfer with reliable connection.

Arrangement

The HM2P80PDA341N9 features a two row, twelve tier design with 72 contacts per side, for a total of 144 contacts. The connector is designed to allow a mating depth of 15.4mm, and it features a shrouded mating cable for reliable operation in tight spaces. The female version of the connector is also available.

Material Specifications

The HM2P80PDA341N9 is constructed with high quality materials for reliable performance. The contact pins are made of copper alloy, and the terminals are constructed from an electrolytic copper alloy with a silver over-plating for enhanced contact performance and reliability. The connector housing is made of polyamides, thermoplastics, or polyetherimide. The design also features a full range of dielectric materials designed to protect against electrostatic discharge (ESD).

Conclusion

The HM2P80PDA341N9 is an ideal solution for embedded backplane applications, due to its combination of Hard Metric and MFI connectors, as well as efficient and reliable operation. Its durable material construction allows for reliable performance in a variety of applications, while its design features ensure the integrity of the connection and protection from ESD. The HM2P80PDA341N9 is the ideal hard metric connector for any application.
