ARINC 2157540-1 is a backplane connector, specifically developed for the aerospace industry. This particular product is a "PressFit" (External Extraction) Connector and consists of a multitude of signal pins that are used to carry all sorts of electrical signals. The product is commercially available in 2, 4, 8, 12 and 24 position versions, with the 2 position version being the smallest and having the greatest signal integrity.

The ARINC 2157540-1 is used mainly in the aerospace industry as a way to increase the speed of data transmission between backplane panels and other system components. This particular connector was designed to provide a reliable and efficient way to connect high-speed data communications. It is also capable of supporting up to 8 differential pairs of 25 MHz signals. The signal lines can be either single-ended or differential mode.

The pressfit (External Extraction) connector design of the ARINC 2157540-1 further enhances the level of convenience, as the external extraction provides easy removal and re-insertion of the connector. It also reduces the amount of effort required for installation, as no tools are needed. Additionally, the signal pins of the connector are extremely small, making them well suited for use in confined spaces or tough to reach places.

In terms of the working principle, the ARINC 2157540-1 is a type of press-fit connector that utilizes two contact fingers on each signal pin. When the connector is plugged in, the two contact fingers form an electrical connection between the two sides, allowing the data signals to be transmitted. The contact fingers also act as a secure retention mechanism to keep the connector firmly in place, minimizing the risk of signal loss or interference. Additionally, the two contact fingers are isolated from one another to prevent short-circuiting of the electrical signals.

The ARINC 2157540-1 pressfit (External Extraction) connector is the ideal solution for any system that requires reliable and efficient high-speed data communication. This particular product is designed to provide superior signal integrity while being capable of fitting into tight, hard to reach spaces. Furthermore, its press-fit structure helps to ensure secure retention of the signal pins in place, reducing the risk of interference or signal loss. With these benefits, this connector continues to be a preferred choice for the aerospace industry.
