Rectangular Connectors are a very common electrical component used in a wide variety of applications, from consumer electronics to industrial machinery. There are several types of rectangular connectors available, each with their own unique characteristics and applications. This article will focus on 91911-31121 Arrays, Edge Type, Mezzanine (Board to Board) connectors and their application fields and working principles.

The 91911-31121 Mezzanine (or board-to-board) connectors provide reliable, high-speed electrical connection between two printed circuit boards. These connectors have a high mating cycle capability, excellent crosstalk and insertion loss values, as well as robust housing and superior shock and vibration resistance. They are available in both double- and single-row configurations and offer up to 98 I/O connections. Ideal applications for 91911-31121 Mezzanine connectors include telecommunications, medical, industrial, consumer electronics, automotive, defense, and aerospace.

The 91911-31121 arrester types are edge connectors specifically designed for electrical connection between two printed circuit boards. They provide excellent retention strength in spite of their low profile and durable contact configuration. Arrester connectors can be used for up to 96 I/O connections and are often used in applications such as medical, consumer, industrial, automotive and military.

The 91911-31121 Arrays provide a high-density connection between two printed circuit boards. The array increases terminal count to up to 99 contacts and also offers high current carrying capacity and excellent crosstalk and insertion loss values. This high-density connection is usually used in a variety of military, aerospace, medical and industrial applications.

Working Principle

No matter which type of 91911-31121 rectangular connector is used, the concept of their working principle is essentially the same. When connecting two printed board circuit boards, the desired connection strength is achieved by inserting a metal pin or a set of pins into the connector. The advantage of this type of connectors is that they are often available with an unlimited number of pins, which provides the user with the ability to choose a specific connection count that best suits their application. Once the connectors are plugged together, the two sides of the connection are mated with the complementary pins on the opposite side.

The 91911-31121 Arrays are similar in their working principle. Once the desired connection count is achieved by inserting the pins, the two sides are connected together and mated by a field of printed contacts. This ensures reliable contact throughout the life of the connector and provides greater current carrying capacity and higher crosstalk and insertion loss performance. For board-to-board applications, the contact fields of array connectors are enclosed in a robust outer shell for protection against accidental contact and damage.

Conclusion

The 91911-31121 rectangular connectors are versatile components designed for a variety of applications. They offer reliable connections, a wide range of I/O connections, and excellent protection from vibration and shock. They are available in a variety of types, including arrester, mezzanine and array connectors, each of which provides a different solution for specific applications. Regardless of the chosen type, the working principle is largely the same, involving the insertion of pins into the connector to achieve the desired connection.
