Backplane connectors are specialized connectors that are used to provide electrical connection between two printed circuit boards. The 74981-302 backplane connector is designed for high-speed, high-density applications. Its design allows for up to 32 differential signal pairs to be pushed through its small form factor, rendering it highly efficient and cost-effective.

The 74981-302 backplane connector is a right-angle SMT connector that allows for up to 2.5 A of power to be transmitted between boards. Its design includes two rows of 16 SMT pins, with the first row utilizing signal pins and the second row using power pins. Each signal pin supports 3 differential signal pairs, and the power pins feature an integrated strain relief component, as well as EMI/RFI resistant grounding features. In addition, the 74981-302 backplane connector also features a rugged metal shell that helps protect the contacts from damage and dust.

In terms of its application field, the 74981-302 backplane connector can be used in small and large-scale industrial applications. It is typically used in the aerospace, medical, military, communication, and automotive industries. It can also be used in high speed data transfer applications, such as Ethernet, Fibre Channel and Infiniband. Due to its small form factor, it can even be used in consumer electronics, such as mobile phones and tablets.

The 74981-302 backplane connector works by providing high speed connections between two printed circuit boards. It utilizes a differential transmission method, in which two conductors send equal but opposite signals. Where the signals are equal and out of phase, the two signals cancel each other out, significantly reducing noise interference. The connector also uses ground pins, which allow for power/ground pins to be sent simultaneously, providing increased power load capacity.

In conclusion, the 74981-302 backplane connector is a specialized connector designed for high speed, high density applications. It is often used in industrial and consumer electronic applications and utilizes a differential transmission method to provide a high speed, low-noise connection between two printed circuit boards. Its design features a rugged metal shell, integrated strain relief, and grounding features, making it both efficient and cost-effective.
