D-Sub connectors are a type of electrical connector that are characterized by their shape, which is a D-type as the name suggests. They are commonly used for connecting computer peripherals, such as keyboards, printers, and modems. The D-sub connector family includes 9-pin, 15-pin and 25-pin varieties, as well as other pin counts. These connectors are constructed of a plastic housing with contacts on the D-sub pins, and typically include both male and female gender options.

66556-3 application field and working principle is literally referred to as Shielded D-sub Connectors. They offer shielding characteristics that are highly superior to the traditional D sub connectors. The shielding characteristics of these connectors are achieved by inserting a metal adapter between the plastic body and the contacts. The shield covers all of the contacts and provides shielding from EMI and RFI signals. This type of connector is commonly used in applications that require high signal integrity and minimal electrical interference, such as mobile phones, networking, and other data communications systems.

The working principle of a D-sub connector is relatively simple. When the male and female ends of the connector are connected, the metal pins on the male connector and the matching female sockets are mated, connecting the two halves. Once the connection is made, a current will flow through the contacts from the male to the female connector. This current is typically used either for powering the device, or for transmitting data from the device.

The 66556-3 application field includes high speed mobile phones, high-speed communication systems, computer networks, power systems, and other applications that require high signal integrity. This type of connector is specifically designed for applications that require improved EMI and RFI shielding characteristics. Its metal adapter offers superior shielding characteristics that are much better than the traditional D-sub connectors.

In conclusion, the 66556-3 Shielded D-sub connector is specifically designed for applications that require improved EMI and RFI shielding characteristics. Its metal adapter provides superior shielding characteristics to ensure that the signals transmitted or received through the connector remain uncompromised. This type of connector is commonly used in applications such as mobile phones, networking, and other data communications systems.
