Introduction

The 91570-112 is a high performance connector designed to interface a range of data communications circuits in a backplane environment. The 91570-112 is a combination of two connectors that contain multiple contacts. The upper and lower parts of the connector have different contact configurations, making them suitable for different types of applications. It is suitable for a diverse range of networking applications that require a high speed connection with high reliability and dependability.

Application Fields

The 91570-112 connector has a wide range of applications in backplane systems. The upper part can be used in source-sink type data transmission applications and the lower part in synchronous data transmission. Examples of source-sink applications include point-to-point data transmission, such as Ethernet, Fibre Channel, and other high speed digital communication technologies. The 91570-112 can also be used in telecommunications backplanes and in recording and storing data, such as keypunch and telephone switchboards.

Working Principle

The upper part of the 91570-112 contains up to twenty-four 200µm diameter pin contacts that are aligned in three equidistant rows. The contacts in the lower part are cantilevered spring contact springs that are overlaid with conductive elastomer. The contacts from the two parts are designed to be inserted firmly together into a 3-row by 8-way connector. The contacts are insulated to prevent short circuits.The contacts are separated into two signal systems, P-signals and S-signals. The P-signals are used for data transmission and are pressure-fit into a molded contact matrix. The S-signals are used to provide power supply to the contacts. The contacts are designed to provide a high-speed, low-resistance connection.

Conclusion

The 91570-112 is a high performance connector designed to provide a reliable and dependable high speed connection in backplane systems. The connector consists of two parts, each containing various contact configurations designed for different types of applications. The contacts, which are separated into P-signals and S-signals, are insulated and pressure-fit into a molded contact matrix to provide a low-resistance connection. The 91570-112 offers a reliable backplane connection for a variety of networking applications.
