D-Sub, D-Shaped Connectors - Housings

D-Sub connectors have become increasingly popular in modern electronic applications, due to their superior signal integrity and robustness. The 170-037-272-020 connector is a popular model from the series, and is commonly used in a variety of applications. In this article, we\'ll discuss its intended application field and working principle.

Application Field

The 170-037-272-020 connector is a part of the D-sub series, which is characterized by a D-shaped metal housing that encloses its contact pins or sockets. D-Sub connectors are typically used on the back panels of computers and are mostly used for data communications applications. In this regard, the 170-037-272-020 connector is suitable for connecting peripheral device cables or cables for various communication interfaces including RS-232, RS-485, V.35, Ethernet, Fiber Optics, and HDMI. They are also used with various audio and video connectors such as RCA and BNC.

The 170-037-272-020 connector is a 25-pin male, so it is designed to connect devices with mating female connectors. In addition to their data communication and audio/video applications, they are also popularly used in industrial automation applications. In this regard, they are typically used to link process automation equipment such as robots, machine tools and automation controllers.

Working Principle

The basic principle behind the working of a D-sub connector is the same in all models. The connecting pins are organized in two rows which are encased in a D-shaped metal housing. This ensures a solid mechanical connection between the connectors. The contact pins are usually made up of brass and are plated with either gold or silver to provide a reliable electrical connection.

In order to connect two devices, the contact pins on both connectors must be aligned and firmly held in place. This is done using a threaded locking mechanism. When the connector is rotated, the two halves of the D-shaped housing are clamped together, and the contact pins make contact with their respective mating pins. This creates a reliable and secure connection.

Another important feature of D-Sub connectors are the threaded mounting holes in the housing. These are often used to mount the connector to a panel or enclosure. This provides a secure mechanical connection and makes it easier to replace or remove the connectors when needed.

Conclusion

The 170-037-272-020 is a 25-pin male connector from the D-sub series. It is widely used in a variety of applications, including data communication, audio/video, and industrial automation. The working principle of the D-sub connector is based on the D-shaped metal housing that is clamped together to make a secure connection between the contact pins.
