D-Sub connectors, sometimes referred to as D-shaped connectors, are a type of electrical connector used in a variety of applications, including computers, telecommunications, industrial automation, automotive, medical and lectronics applications. The term "D-Sub" comes from the "D-shaped" metal shield that covers the contacts of the connector. This metal shield protects the contacts from dust, dirt and other contaminants, and acts as a ground for the entire connector assembly.

The 7291 is a type of D-Sub connector, and is characterized by two D-shaped shells that hold a row of pins or sockets. The number of pins and sockets can be customized to accommodate a variety of application needs. D-Shaped connectors are typically used for computer communications such as Ethernet and serial communications, but can also be used for medical and industrial applications.

The 7291 D-Sub connector features an annular semi-recessed contact design that allows for a wide range of applications. The annular contact is a recessed contact that comes in a variety of sizes and is swaged (crimped) onto the end of the pin or socket. This design is highly flexible and can be used in applications where space may be limited. Additionally, the annular contact ensures great electrical conductivity and supports very high performance data rates.

The 7291 connector is primarily used in applications requiring multiple contact points and reliability. Due to its semi-recessed design, the contact makes direct contact with the connector surface and offers extremely low resistance. This feature allows for low crosstalk and signal integrity, making the 7291 an ideal choice for applications where signal integrity is of utmost importance.

Additionally, the 7291 includes an optional jackscrew locking system for increased reliability. This system is designed to keep the connectors firmly connected in environments with high vibration or shock loads. The jackscrews are made of stainless steel and are highly resistant to corrosion and wear. The jackscrews are also adjustable, allowing for easy installation and alignment of the connector.

The 7291 D-Sub connector is a reliable and versatile solution for a wide variety of applications. Its annular semi-recessed contact design allows for efficient electrical performance and signal integrity. Additionally, the optional jackscrew locking system ensures improved reliability in harsh environments. This makes the 7291 an ideal choice for high performance data communication applications.
