D-Shaped Connectors - Centronics

D-shaped connectors are physical interfaces that allow two devices to connect and exchange data. They are most commonly used to connect computers and printers. The D-shaped connector that most people are familiar with is known as Centronics. This type of connector was developed by Centronics Corporation in the 1970s and is widely used today.

The Centronics connector consists of two parts, the male and female connectors. The male connector has 36 nubs (pins) arranged in two rows of 18, with a rounded body shaped in a “D”, hence the name. The female connector has 36 openings for the male connector’s pins. The two connectors mate together, and are held together by a latching mechanism.

The 3549-1001 type of Centronics connector is a standard type of connector used in most printers and computers. It is used for IEEE-1284 parallel connection, which is the method of data transfer used by most computers and printers before the advent of USB cables.

The IEEE-1284 protocol sends one byte of data at a time over a parallel signal, which is essentially a 2-way communication using 8 wires. This is referred to as “bidirectional” transmission, since the device being connected can both send and receive data.

The 3549-1001 Centronics connector can be found on a variety of devices, including printers, scanners, external hard drives, and other computing devices. This type of connector is particularly useful for connecting devices in a networked environment, since each device can send and receive data.

The working principle of a Centronics connector is based on the creation of a series of electrical connections between the male and female connectors. When the two connectors are mated, the electrical contacts are made and data can be exchanged.

When the connectors are disconnected, no connection is made and no data can be exchanged. In addition, the latching mechanism ensures that the connection between the two connectors is secure, so that the data being exchanged is not corrupted.

In summary, the 3549-1001 Centronics connector is a standard type of connector used for IEEE-1284 parallel connection. It is commonly found on a variety of devices, such as printers, scanners, and external hard drives. The connector works by creating a series of electrical connections between the male and female connectors, which allows data to be exchanged in a secure manner.
