D-Sub Connectors are used in many applications and environments, from computer systems to industrial equipment. The 2DA-31SF171 is a D-Sub Connector that is used in a variety of applications. This article will discuss the application field and working principle of the 2DA-31SF171.

The 2DA-31SF171 is a double-decked connector that is ideal for applications where space is limited, as it is one of the smallest D-Sub Connectors available. It features two high-density 50-pin cable insertions with a 2.54mm centreline. The double-deck design allows for two 50-pin cable insertions within a considerably small size. The 2DA-31SF171 also features solder terminals, which are designed for easy mounting and soldering, and a metal bracket for additional support.

The 2DA-31SF171 is typically used in a variety of applications including instrumentation, test and measurement, and communication systems. This D-Sub Connector is well-suited for this application as it provides reliable connectivity as it has excellent mating durability and is highly resistant to shock and vibration. Additionally, its easy installation and removal make it a convenient and efficient option for any application.

The working principle of the 2DA-31SF171 is relatively simple. The connector is assembled by the push-in interlock system which locks the connectors securely in place. The keyed housing provides precise orientation and prevents mis-insertion. The interlock function can be unlocked by pressing the two interlocks with a flat object such as a screwdriver. Once unlocked, the connectors can be removed from each other.

The 2DA-31SF171 has two crimp contacts: one for the female and one for the male connector. The female connector has gold plated terminals that are inserted into the contact cavities. The male connector has silver-plated terminals which are crimped over the inner conductor and soldered to the cable shield. The mating contacts are designed to ensure a reliable electrical connection.

In conclusion, the 2DA-31SF171 is a small high-density D-Sub Connector which is designed for a variety of applications. Its double-deck design and solder terminals provide secure and reliable connections. The working principle of the connector relies on its push-in interlock system, keyed housing, and crimp contacts. As a result, these features make the 2DA-31SF171 an excellent choice for any application where space is limited.
