170 Series, D-Sub, D-Shaped Connector Housings

The products in this family are specifically designed for use with D-subminiature style connectors. These connectors provide a means to insert electrical contacts that have been applied to discrete wires. The name "D-subminiature" refers to the shape of the mating end of these connectors, which resembles the letter "D". These connectors were initially introduced due to their relatively high interconnect density compared to other options available at the time. To form a complete connector assembly, an additional component called a backshell is required. The backshell encloses and protects the connection between the connector and the discrete wires, providing strain relief and shielding against environmental factors such as moisture, dust, and debris. It helps ensure the integrity and longevity of the connection. It's important to note that there are similar products available that allow for soldering discrete wires directly in place within the connector. These products are grouped separately from the ones designed for use with applied contacts. Additionally, similar items are also available for mounting directly onto a printed circuit board, offering alternative solutions depending on the specific application requirements. In summary, the products in this family are designed for D-subminiature style connectors, allowing for the insertion of electrical contacts applied to discrete wires. A backshell is required to complete the connector assembly, providing protection and strain relief. It's worth noting that there are alternative options available, including products for soldering wires directly and items for mounting onto printed circuit boards.
