D-sub, also called D-shaped connectors, are electrical connectors widely used in the telecommunications landscape, and are also referred to as D-shaped connectors, flat connectors, and round connectors. This discussion covers the 745171-5 application field and working principle.

Application Field

The 745171-5 D-sub connector is part of the Cinch Connectors family and can be used in a variety of different applications. It is used primarily for data transmission between computers and telecom networking systems. It is also used in the industrial, transportation, power, and communication fields. The 745171-5 D-sub connector has a standard diameter of 1/2 inch and is usually mounted in a 19-pin backplane or a 2x18 backplane depending on the application. It is designed to support data transmission rates of up to 30Mbps, and it is often used for data rates up to 10Gbps.

Working Principle

The 745171-5 D-sub connector is a shielded male connector with 19 pins gold plated for low contact resistance. The top side of the connector is made from plastic while the bottom side is made from metal, with stainless steel contacts to provide a secure connection. The connector is designed to allow a cable to be plugged in the back of the connector and secured via nuts and screws. The cable is usually a twisted pair or ribbon cable, and the connectors have various accessories such as a hood and a backshell to enable connection. The contact pins are arranged in two rows and are designed for a low insertion force, so they can be plugged and disconnected without having to use a tool.

The connectors feature a single layer of shielded RF shielding to reduce crosstalk and ensure a reliable connection. The cable is inserted into the top side of the connector and the secured using screws at the back. The cable is then connected to the corresponding contacts on the other side of the connector. The connector is then able to transmit data signals across the components within the system, allowing the system to communicate with other devices.

The 745171-5 D-sub connector is designed with low contact resistance and is suitable for a wide range of applications. It is suitable for data transmission between computers and telecom networking systems as well as in the industrial, transportation, power, and communication fields. The 745171-5 D-sub connector is usually mounted in a 19-pin backplane or a 2x18 backplane depending on the application, and is also compatible with various accessories such as a hood and a backshell to enable connection.
