Introduction

D-Sub connectors, also known as D-Subminiature connectors, are a type of electrical connector commonly used in a variety of applications. The most common type of D-Sub connector is the DB-MF17W2SA156. This particular model of D-Sub connector is a miniature D-Sub 9 that features an extended current rating up to 5A at 250VAC.

Applications

The DB-MF17W2SA156 D-Sub connector is used in a wide range of applications. The most typical use cases include industrial and scientific instrumentation, radios, digital cameras, test equipment, computers, and AV equipment. Due to its small size and current rating, the DB-MF17W2SA156 is also well-suited for space-restricted applications and even automotive uses.

Structure

The DB-MF17W2SA156 is a miniature D-Sub connector, which means that it features a rounded corner, rather than the traditional right-angle type connectors. The body is constructed out of conductive metal with a plastic insulator fitted inside. The insulation prevents electric leakage and short circuits. On the front of the DB-MF17W2SA156, there are 9 pins arranged in 3 rows. The pins are gold-plated to ensure a reliable electrical connection.

Pin arrangement

The DB-MF17W2SA156 features 9 pins arranged in a design known as the T568A/B pin arrangement. This arrangement is based on the T568A wiring standard, which defines the pin assignment for the pins in the connector. The T568A/B arrangement is most commonly used in networking applications, such as Ethernet cables. In the T568A/B arrangement, each pair of pins is grouped together and has its own color-coded sleeve. The individual pins are also color-coded in accordance with the standard.

Working Principle

The DB-MF17W2SA156 is designed to provide a dependable electrical connection between two devices. To maintain the connection, the pins are held together with a machined contact, which ensures a secure connection. When devices are connected, electric current passes through the pins of the DB-MF17W2SA156 connector, allowing data and signals to be transmitted between the devices. As the current passes through the pins, it is insulated with the plastic insulation, preventing any electric leakage or short circuits. Furthermore, the gold plating on the connector pins helps to minimize resistance and ensure that the signal being transferred remains clean and powerful. The gold plating also helps to reduce corrosion and improves the overall lifespan of the DB-MF17W2SA156 connector.

Conclusion

The DB-MF17W2SA156 is a miniature D-Sub connector that offers an extended current rating of up to 5A at 250VAC. It is used in a variety of applications, ranging from industrial and scientific instrumentation, to networking applications. The DB-MF17W2SA156 features 9 pins arranged in a T568A/B pin configuration, which ensures a reliable electrical connection. The connector is designed with a machined contact and a plastic insulation to prevent electrical leakage and corrosion, and the gold-plated pins ensure a strong signal transfer.
