Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are interconnect elements that are used for linking two or more identical printed circuit boards (PCBs). They are sometimes referred to as edge connectors, mezzanine connectors or edge-type connectors. The board-to-board connectors allow for PCBs to be connected together within a short distance, as well as providing excellent signal integrity and allowing for multiple connections to be made quickly.

91921-31131 rectangular connectors are of the edge-type variety, designed for surface mount applications and come equipped with a row layout of between 20 to 32 contacts. Embedded within the rectangular connector are a variety of contacts that help provide reliable signal transmission and high current rating capacity. As well as these, the 91921-31131 connector also comes with an optional heating element, which is especially useful for harsh environments.

The 91921-31131 connector is an example of a mezzanine, or board-to-board, system, in which two PCBs are connected together using the connector. The advantages of using a board-to-board connector include the ability to save space due to their small size, as well as being able to plug and unplug the connectors very quickly. They are also very easy to install, meaning that the amount of wiring and soldering is reduced significantly. Another benefit of using these connectors is their excellent signal integrity, as they are designed for high-speed applications.

The working principle of the 91921-31131 connector is very straight forward. Inside the connector are a number of pins that are arranged in a row. The pins make contact with the PCB, and the connection is solidified by pressing down on the top cover of the connector. This method is a very secure and reliable way of ensuring a strong, reliable connection between the two PCBs.

The contacts within the connector are shielded, meaning that they are protected from any external interference. This is important, as external interference can cause disruptions to the signal that is sent through. It also helps to prevent the contacts from becoming damaged through wear and tear, as the protective shielding helps to reduce metal fatigue. The connector also comes with an optional heating element, which can help to provide protection against extreme temperatures and other hazards.

In conclusion, the 91921-31131 connector is an example of a board-to-board connector, designed for surface mount applications. Its row layout consists of 20 to 32 contacts, and they provide excellent signal integrity and high current rating capacity. The connectors are available with an optional heating element, which makes them particularly suitable for harsh environments. Additionally, the working principle of the connector is very simple, as it is simply a matter of pressing the top cover of the connector to make a connection between the two PCBs.
