443961-3

D-Sub connectors form a relient and cost effective way of connecting devices. The most common type, 443961-3 is an example of a 15-pin, 3-row male connector. D-Sub connectors are widely used in analog audio, digital video, and communication protocols, such as RS232, RS485, Ethernet, Firewire, and more. This type of connector was popular when long-run wires were used, but is still very popular in some applications, even though newer technologies have been developed.

The 443961-3 connector was designed to meet standard and safety requirements for the American National Standards Institute (ANSI). It has three rows of 15 pins each. Inside the connector, each row has two dielectric sleeve-sized grooves and conductive flats. On the outside of the connector, there are three insulated sleeves, with each row having an additional flat. The insulation helps to protect the wiring from damage.

The main application field for 443961-3 connectors is computer peripherals such as hard drives, sound cards, monitors, and motherboards. It is also used in some automotive applications and in industrial machine control. The 443961-3 is also often used in the medical field. It is commonly found in imaging equipment, cardiac catheters, respirators, and other medical devices.

To understand the 443961-3 connector’s working principle, it’s helpful to consider how the pins and insulation interact. Generally speaking, the connector has two inner conductive rails, with each pin in the row having a corresponding groove. To establish a connection, the inner conductive rails are connected to the corresponding pin’s groove, thus providing a electrical path between the pin and the circuit. The insulation sleeves also provide a protective layer to prevent shorting out or contact with other surfaces.

The 443961-3 connector is not the only type of D-Sub connectors, although it is one of the most popular. Other varieties have been developed for different applications, with different numbers of pins and different insulated sleeves. All D-Sub connectors follow the same basic working principle, and they are all used in a variety of applications.
