D-shaped connectors, also known as Centronics connectors, are a type of electrical connectors designed to connect together computers and peripherals. These connectors are typically used for computer printer cables, or for transferring data between two computers via a serial port. Centronics connectors are characterized by their D-shaped metal shells that contain two rows of nine pins each. The pins are arranged in an alternating pattern, with a ground pin located at the center of the connector.

The most common type of Centronics connector, the 555020-2, is a reversible, high density connector that is used for data transfer. This type of connector is typically found on personal computers and peripheral devices such as printers and scanners. It is also becoming increasingly popular in the telecommunications industry where its high-speed data transmission and robust build make it ideal for digital subscriber line (DSL) applications.

The standard 555020-2 Centronics connector allows up to nine different pins to be used in a single connection. The pins are arranged in two rows, with the ground pin located in the middle. The connector has two locking mechanisms that ensure the connection remains secure and that the data is not lost due to loose connections. Additionally, the connector comes equipped with a buffer to provide extra protection against electromagnetic interference.

Centronics connectors are available in a variety of shapes and sizes, which can make it difficult to identify the correct connector for a particular application. However, the general principles of operation remain the same regardless of the shape or size. Generally, when considering a Centronics connector, the most important factors to consider are its data transfer rate, its current-carrying capacity, its insulation resistance, and its ability to meet EMI requirements.

The 555020-2 Centronics connector is a simple yet effective choice for transferring data between two digital devices. Its reversible design and high-speed data transfer rate make it ideal for applications where low latency is a priority. Furthermore, its reliable locking mechanism ensures a secure and long-lasting connection. As such, this type of connector is often chosen for applications such as USB, Ethernet, and Firewire connections.
