• Introduction

Backplane Connectors are specialized connectors that connect two or more boards or devices back-to-back in order to enable the sharing of power and/or data between them. One such specialized backplane connector is the MMA25-0111H1. Its application field and working principles will be discussed in detail in this article.

• Application Field

The MMA25-0111H1 is widely used in industries such as telecommunications, medical equipment, automotive, avionics, and industrial automation. It is an ideal solution for applications that require high performance and secure signal transmission. It provides a connection between two boards and its customisable insert system enables the matching of board-to-board dimensions. This makes it suitable for a wide range of applications, including inline assembly, mounting rails, enclosure, board-to-board connections, and combinations of these.

• Working Principle

The MMA25-0111H1 works on the principle of differential pairs. It consists of multiple differential pairs of conductors which are enclosed by insulation and form a connector insert. The contacts of the insert are connected to the board or the cable. Signals transmitted between two devices connected by the MMA25-0111H1 are transmitted through the differential pairs, which eliminates the need for multiple interconnects between the devices. The differential pairs enable the transmission of signals over a distance with minimal signal degradation due to parasitics, crosstalk, and other factors.The MMA25-0111H1 is designed to provide high-speed, robust connections between two boards or a board and a cable. It is capable of supporting up to 8 differential pairs with a bandwidth up to 5Gbps at either a 50ohm or a 100ohm impedance. It is also designed to support the power and ground signals, allowing them to be transmitted through the same connector.The MMA25-0111H1 is equipped with multiple features which make it suitable for a variety of applications. It provides a robust connection and is designed for durability, with a current carrying capacity of 20A and a mechanical durability of up to 200 mating cycles. Furthermore, it is compliant with multiple industry standards, such as IEC 60603-2, and MIL-STD-810G.

• Conclusion

The MMA25-0111H1 is an ideal solution for applications requiring high performance and reliable signal transmission. It is designed for durability and can provide robust and secure connections up to 8 differential pairs at bandwidth up to 5Gbps. It is versatile and compliant with multiple industry standards, making it suitable for a wide range of applications.
