D-Sub Connectors are a type of electrical connector widely used in various electronic devices and have found their use in countless applications. One such connector is the 172-E25-103R911, which is one of the members of the widely-used 25-pin D-sub connector family. This article explains the applications and outlines the working principle of the 172-E25-103R911.

The 172-E25-103R911 D-Sub connector is a 25-pin female connector with black (in case of steel) or light gray (in case of aluminum) insulated mountable housing. The plug is composed of two rows of 25 contact pins, arranged in a 5.08mm pitch, and often uses tinned-copper alloy contacts. These connectors are primarily used to interface peripheral devices with the central processing unit in an electronic system.

Common applications of the 172-E25-103R911 include computer networking, digital video, audio, and data transmission, as well as control and communication systems. These connectors are also used in machines and plant automation, automotive electronics, robotics, and many other applications. As they are quite reliable, the maximum operating voltage for these connectors is 250V.

The basic principle of this connector is simple. The electrical connection between the connector and the socket is made through 25 contacts. When the connector is inserted into the socket, these contacts are pushed into the socket, establishing an electrical connection. This connection is secured by the connection of the four clips that hold the connector to the socket. The contact pins then make contact with the back of the socket, ensuring a secure connection. In addition, the thickness of the contacts and the shape of the two rows of pins provide shock and vibration protection.

The 172-E25-103R911 is a rugged and reliable connector that has found its use in countless applications. Its features, namely its two rows of 25 contact pins, its high current-carrying capacity, and its secure connection, make it an excellent choice for a wide variety of electronic systems.
