DAM7W2SR

D-Sub Connectors

D-Sub connectors, also known as D-subminiature connectors, are high-performance electrical connectors that use a D-shaped metal shell. They are well suited for applications where space on the back panel is at a premium, and provide robust connections for power, data and other signals. The most common format is the DB25 (or DE9), which can accommodate up to 25 pins and is used for interfacing various serial devices. The DAM7W2SR is one type of D-Sub connector that is designed for applications requiring a high count of pins (e.g. video distribution). This article provides an overview of DAM7W2SR application fields and working principle.

Application Fields:

The DAM7W2SR is a 9x25-pin, high-density D-Sub connector developed for use with digital video applications. It is ideal for multimedia, broadcast, and medical equipment as well as for use in industrial and communications markets. It is a low-profile, threaded interface connector designed to support the demanding requirements of transmit and receive serial digital video. It is intended for use in harsh environments and includes features such as optional screw-secured thread or flange lock for secure assembly, kinked strain reliefs for enhanced bend endurance, and optional gold plated contacts for increased signal integrity.

Working Principle:

The DAM7W2SR is a low profile, threaded connector specifically designed to reduce the amount of space between two connecting devices. It features a 9x25-pin configuration with each pin arranged in a staggered pattern. This feature allows for a thinner, smaller package that allows for more signal pins to be packed into the same space as an equivalent non-staggered configuration. The pins are inserted into a die-cast aluminum shell, and the ground shell is then compression clamped with the mating housing. The contacts feature a 4-point spring contact design for enhanced electrical performance. This helps to ensure signal integrity and reliable performance even in the most demanding applications. The contacts also feature a dual wipe contact that minimizes cross-talk between pins, which results in improved signal quality.

Conclusion:

DAM7W2SR is a high-density D-Sub connector with 9x25-pin configuration. It is designed to reduce the space between two connecting devices, and features a 4-point spring contact design for improved electrical performance. It is well suited for demanding applications such as multimedia, broadcast, and medical equipment, as well as for use in industrial and communications markets.
