Rectangular connectors have long been a popular type of connection in the electrical and electronics industry, and the 91911-21311 form factor is no exception. This connector has a reliable, robust design which is suitable for a variety of applications in the home, office, automotive, and other fields. In this article, we will discuss the application field and working principle of the 91911-21311 connector, as well as look at the various types of connectors in this form factor.

Application Field

The 91911-21311 form factor is an ideal choice for a variety of applications. Its rectangular design offers excellent electrical performance in high-temperature and harsh environment conditions. Additionally, the connector\'s flat design enables it to fit into narrow spaces and its durable construction can handle the vibration of mobile applications. The 91911-21311 is suitable for use in demanding industrial applications, such as in the automotive, aerospace, electronics, telecommunications, and medical fields.

Working Principle

The 91911-21311 form factor is a modular connector which features a mash board and half-pitch through-hole receptacle contacts. The contacts are arranged in a square pattern which is typically 19.13mm x 19.13mm, and each connector is composed of an inside row receptacle, an outside row receptacle, and a backplane contact. The outside row receptacle houses two rows of contacts with straight-through and offset-entry options, and the inside row receptacle can house a single row of contacts. The backplane contacts feature two rows of pins for dual-row board-to-board connection.

When the connector is mated, the male and female contact are forced together by a spring-clasp mechanism, which creates a reliable contact between the two. The clinch design of the 91911-21311 enables the signal to travel undiminished though the cable. Additionally, the connector is designed to mate with a corresponding connector, which enables the signal to be passed through without any interference.

Types of Connectors

The 91911-21311 form factor is available in three different types of connectors: arrays, edge type, and mezzanine (board-to-board). The array connectors the most commonly used type and feature both inside and outside row receptacles. The edge type connectors feature the same inside row receptacle as the array connectors and are designed to be mounted on an edge of a board. The mezzanine (board-to-board) connectors are a compact form of the array connectors and feature a single row of contacts. All three types of connectors utilize the same spring-clasp mechanism for a secure connection.

Conclusion

The 91911-21311 form factor is a reliable and robust connector which is suitable for a variety of applications. Its rectangular design offers excellent electrical performance in high-temperature and harsh environment conditions and its flat design enables it to fit into narrow spaces. Additionally, the connector is available in three different types: arrays, edge type, and mezzanine (board-to-board) and all three provide excellent contact reliability thanks to the spring-clasp mechanism.
