Backplane connectors are used to connect one printed circuit board (PCB) to another, providing the necessary electrical pathways for data transmission. The HM2P95PDE121N9 is a Hard Metric, Standard-based backplane connector capable of both coaxial and differential signal applications and is designed to meet stringent requirements for signal quality and reliability. In this article, we will explore the application fields and working principles of this popular connector.

Application Fields

The HM2P95PDE121N9 backplane connector is most commonly used in high-speed digital signal applications, such as desktop computers, server systems, and communication equipment, due to its excellent signal integrity performance. It has also been successfully applied in high-density data centers, and, thanks to its low crosstalk levels, it is often used in complex network environments. Furthermore, its high-speed transmission capability makes it suitable for use in Storage Area Network (SAN) and Fibre Channel (SAN) environments.

Working Principles

The HM2P95PDE121N9 is a Hard Metric, Standard-based backplane connector with an impedance of 95 Ohms. It features an industry-standard, two-point contact design that ensures reliable electrical connection. Each pin or pad has two contact points which provide very low crosstalk, low-insertion loss, and high signal integrity. The contact points are gold-plated to avoid oxidation and ensure reliable connections even after repeated insertion.

The HM2P95PDE121N9 is designed for differential or single-ended signal applications, with its differential signals providing much better noise immunity than its single-ended counterparts. Furthermore, it is capable of transmitting data at very high rates, up to 12.5 Gb/s, and it has a dielectric withstand rating of 350V AC. This makes it suitable for use in high-voltage applications, such as telecom gear and servers.

To ensure reliable transmission, the HM2P95PDE121N9 connector has been designed so that all 12 contacts are fully shielded to protect them from EMI. Furthermore, the ground plane is designed with a large metallic surface area which helps to keep the EMI low. The connector also features two latching mechanisms which ensure that the connector remains firmly connected and ensure that there is no risk of accidental disconnection.

Conclusion

In conclusion, the HM2P95PDE121N9 backplane connector is a Hard Metric, Standard-based connector designed for high-speed digital signal applications. It has a two-point contact design which ensures reliable electrical connections with low-insertion loss and low crosstalk. Furthermore, it is capable of transmitting data at high rates, up to 12.5 Gb/s, and it has a dielectric withstand rating of 350V AC. Combined with its shielding and latching mechanisms, these features make the HM2P95PDE121N9 an excellent choice for high-speed digital signal transmission.
