MMA25-0261K1 Application Field and Working Principle

The MMA25-0261K1 is a specialized backplane connector designed to provide an Ethernet interface connection between multiple cards in a card cage environment. The connector is designed to provide a Plug-and-Play installation experience while also providing significant features over traditional Ethernet connectors, including protection against electrical interference, dust accumulation, and shock.

The MMA25-0261K1 connector is designed to be used in a variety of industries, including military, aircraft, automotive, telecommunications, industrial automation, and medical applications. The connector’s durability and dependability makes it suitable for use in harsh environments, such as extreme temperatures and humidity, as well as electromagnetic interference.

The MMA25-0261K1 works by utilizing an eight pin terminal located at the rear of the connector, to which up to four Ethernet ports can be connected. These ports are then connected across two 56-pin connection segments. The pins are spaced at a 5mm pitch, and are sealed by environmental “O” rings, providing reliable protection against dust particles, vibration, and outside contaminants.

In addition to its environmental protection capabilities, the MMA25-0261K1 offers a number of features designed to maximize the performance of any application. The connector is designed with an internal strain relief system, ensuring secure connections between the cable and connector. The internal contact force of the connector is precisely adjusted to ensure a reliable connection between the board and cable. The connectors are also designed with circular, recessed contact pads to reduce repeatable errors during blind mating.

The MMA25-0261K1 also features a “zigzag” contact configuration, which enables multiple card compatibility and minimizes pin displacement. The connector also offers the ability to support multiple combinations of data speed, ranging from 10 Mbps to 10 Gbps. Finally, the connector is designed with the ability to detect if a port is connected and can signal up to five times in the event of a failure.

The MMA25-0261K1 has been widely adopted throughout multiple industries and is seen as the benchmark for reliable Ethernet connections. Its wide range of features and protection capabilities make it an ideal choice for use in equipment that is operating under harsh conditions or requires extra protection against outside interference.
