D-Sub, D-Shaped Connectors - Housings

D-Sub, D-Shaped Connectors are versatile and popular connectors used in conjunction with a variety of signals. They are most easily recognized by their closed metal housings with the common \'D\' shape. The housings feature two parts; a male and a female. The male is the connection that attaches to the cable and the female is the connection that mates with the device. The 212491-8 D-Sub connector is the popular shell size 8 metal housing.

When selecting a D-Sub connector housing, there are a few considerations such as the number of pins, the number of rows, the shell size and hoods. The 212491-8 D-Sub connectors meet the MIL-DTL-24308 Standards Criteria which allow use in aviation, military and space applications. It features two rows of 8 pins, has an outside diameter of 0.193 inches and a depth of 0.53 inches making it a popular choice for high-density applications.

These connectors are designed with both the male and the female contacts to mate together when paired. When mating them, the contacts are normally spring-loaded inside the connectors housings and as the male housing is inserted in to the female housing, the male pins push in to the female contacts. This creates a contact pressure between the two allowing for a reliable, electrical connection.

Another important consideration is the hood for the D-Sub connector. The hoods help to protect the connection from EMI/RFI and other environmental contaminants. These hoods help to minimize the problems of EMI/RFI interference by providing a Faraday cage-type enclosure. These hoods are constructed from metal and feature a variety of connection types including solder tails, twist-lock and quick disconnect options.

The 212491-8 D-Sub connector is widely used for a variety of applications such as I/O connections, communications and instrumentation. Its versatile design and features such as a shielded design and the ability to have crimp or soldered connections offer flexibility to the user. In order to ensure compatibility between devices, all D-Sub connectors come with a comprehensive set of industry standard terminals and housings.

High performance applications that require a durable and reliable connection benefit from the 212491-8 D-Sub connector. The combination of versatile design and durable construction make this connector a sensible choice for many different applications.
