D-Sub Connectors: FCC17B25SB240 Application Field and Working Principle

The FCC17B25SB240 is a D-Sub connector a commonly used type of electrical connector. A D-Sub connector is composed of two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, updated electrical, and common mating interfaces. Although they are found in a wide array of different shapes and sizes, in general, it is said that these components are appropriate for applications such as connecting computers or other systems for the purpose of exchanging signals and data.

The History of D-Sub Connectors

D-Sub connectors originated at the dawn of the electronics industry. German engineers developed them in the late 1930s as a solution for producing a mechanical and electrical connection between two components. From then on the design has been continually improved. In the 1950s due to the emergence of television sets the need to transfer analogue signals grew significantly, and D-Sub connectors were quickly recognized as an ideal solution for the task.At present, the design is starting to become a bit dated. With the emergence of smaller, more compact designs such as USB, HDMI, and SFP connectors, the market for D-Sub connectors has declined significantly. That said, they continue to have a place in many applications, particularly those that require mechanical strength and protection in hostile environments.

The Anatomy of D-Sub Connectors

The anatomy of D-Sub connectors and its components must first be understood to appreciate its applications. In general, these components feature a pre-molded outer shell that has a curved “D”-shaped metal plate attached to two or more rows of metal pins. The plastic housing allows for easy connecting, and the metal plate inside ensures a reliable electrical connection between components by grounding itself to the other electrical equipment. To facilitate the insertion of a mating connector, each row of pins is divided into two parts by a plastic insulation material. The insulation material also helps to ensure that the pins don’t accidentally short out and create a short circuit.

FCC17B25SB240 Application Field and Working Principle

The FCC17B25SB240 D-Sub connector is a 25-pin male to male type and has a variety of applications in the industry. It is used for several purposes, including providing power supply, signal connection, and data communication.The FCC17B25SB240 is designed with a commercial diameter of 17.45mm and a height of 25.4mm when mated. In order to ensure its stability when used in an enclosure, the connector is equipped with a housing seal which prevents dirt, dust, and moisture from entering. It is rated to operate in a temperature range of -40°C to + 105°C and offers a mating cycle of 500 times.The working principle behind the FCC17B25SB240 is simple. When the plug is inserted into the socket, the inner edges of the D-shaped metal shield make contact with the pin in the rear side of the socket, grounding the ground wire for the connection. The pins then make contact with the socket pins and the connection is completed. The metal shield ensures that the connection is secure and protects it from external damage or debris.

Conclusion

D-sub connectors are an important type of connector found in many electronic applications. The FCC17B25SB240 is a 25-pin male to male type D-Sub connector used to provide power supply, signal connection, and data communication. Its robust design ensures it is able to survive and perform reliably in harsh conditions and its 500 mating cycles ensure long-term use. As a result, the FCC17B25SB240 is a dependable choice for a wide range of applications.
