Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) – 91911-31425 Application Field and Working Principle

Rectangular connectors are a general purpose electrical connection system often used in data and telecommunications systems. As the name suggests, these connectors are used to interface with rectangular circuit boards and are composed of a number of individual pins arranged in an array. They are typically made from a high-density plastic or metal housing that is then sealed with a screw-on cover. While there is a variety of styles, configurations, and arrangements, common to all rectangular connectors is the presence of two or more sets of pins that when mated together, form an electrical connection between the two components.

There are three primary types of rectangular connectors – arrays, edge type, and mezzanine, each of which has specific applications.

Arrays

Array connectors feature an array of pins arranged in a straight line, similar to a ribbon cable. The pins are arranged in even increments to make up the entire length of the connector. Array connectors are found in a variety of computer, data, and information systems. They are known for their simple design and ease of use but can be susceptible to electromagnetic interference (EMI).

Edge Type

Edge type connectors are similar to array connectors in that they utilize pins arranged in even increments along a straight line. However, edge type connectors are designed with a claw or groove, like those found in power connectors, that secure the connector to the circuit board to which it is attached. The pins on edge type connectors are generally thicker to allow for a better electrical connection. These connectors are more reliable than array connectors because they are more resistant to EMI.

Mezzanine (Board to Board)

Mezzanine connectors are a type of board-to-board connector specifically designed for joining two separate printed circuit boards together. This type of connector is becoming increasingly popular in the electronics industry due to its ability to provide high-speed signal integrity and low signal loss. In addition, mezzanine connectors offer a high level of flexibility, as they can be used to connect boards of varying sizes and thicknesses. In addition, they can be used to connect two boards of a single system or two different boards in a system with a minimum of crosstalk or noise.

91911-31425 Application Field and Working Principle

The 91911-31425 is a right angle type connector designed for board-to-board applications. It features two rows of 50-pin right angle connectors. Each pin is placed at a 0.8 mm pitch and can be swapped out with a different type of pin in order to meet the needs of the application. The connector is designed to provide high-speed data transmission with no signal loss. The contacts are gold plated and rated up to 1A, ensuring that the connector is suitable for a variety of applications. In addition, the connector is designed with an anti-EMI coating to further protect against interference.

The 91911-31425 rectangular connector also features a ruggedized housing and a latch mechanism that securely locks the two boards together. This type of connector is ideally suited for applications that require robust connectivity, such as those in industrial and automotive applications. Overall, the 91911-31425 is an ideal solution for applications that require a reliable, secure connection.
