Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are a type of connectors used in a variety of applications. In particular, the 91900-21221 type of connector is designed for use in array-type edge and mezzanine long pin configurations, and are available in 0.7 mm, 0.8 mm, and 0.9 mm pitch sizes.

The 91900-21221 are ideal for applications requiring a small package size and a high number of pins. They are also suitable for board-to-board electrical connections, as their small size facilitates easy integration between boards. They feature high-reliability conductor contacts that are spaced with very precise centers for reliable mating and connection. Moreover, these connectors are also designed to be mechanically secure, utilizing an insulated ground contact plate and crimped ground wire at both the mating end and the header end.

In terms of working principles, the 91900-21221 connectors use a mezzanine edge configuration, wherein the female connector (or “header”) is located at one end and the male connector (or “pin”) is located at the other end. This configuration ensures that the connectors remain securely connected without the risk of accidental disconnection. The connector also utilizes a mechanical back-lock system that requires both the mounting surface and the header to be locked in place to create a secure connection. The pins (male connectors) of the 91900-21221 feature press-fit contact sleeving, which helps to ensure a secure electrical connection between the two components.

The 91900-21221 connectors are also designed with a wide range of features that ensure a reliable connection and performance in various environments. For instance, the connector has an extended temperature range of -55℃ to +125℃, making it suitable for a wide range of applications. Additionally, the entire connector is designed with a strong polymer construction that is resistant to mechanical and chemical stressors, which makes it suitable for applications where strong shocks and vibrations are common. The connectors are also designed to have an operating life of up to 10,000 mating cycles, providing a highly reliable connection in long-term applications.

The 91900-21221 are commonly used in a variety of applications, including communication, medical, automotive, consumer electronics, green energy, and industrial control. These connectors are designed to provide a reliable, secure, and long-lasting connection that is suitable for a range of applications. Additionally, they are available in a range of pitch sizes to accommodate different circuit requirements and ensure a reliable connection. Furthermore, the connectors are designed to be compatible with a range of existing connectors, making them suitable for applications requiring integration with other connector types.

In conclusion, the 91900-21221 are a type of connectors used in a variety of applications for their reliable performance and long-term reliability. They feature a mezzanine edge configuration, ensuring a secure connection without the risk of accidental disconnection. Additionally, the connectors are designed with a range of features that are suited for various environments, as well as high-reliability conductor contacts. Furthermore, these connectors are commonly used in communication, medical, automotive, consumer electronics, green energy, and industrial control applications.
