D-shapped connectors, sometimes known as Centronics connectors, are some of the most widely used connectors in communication and computer applications. Named after printing equipment company Centronics, the d-shaped connector features two d-shaped ends with 11-25 pins which join together to create a secure connection. Often used in parallel port applications, including a variety of computer peripherals such as printers, scanners, modems, digital cameras, etc, the d-shaped Centronics connector is becoming an increasingly popular choice for data transfer.The two sides of the Centronics connector each feature a d-shaped hole with pins around the outside edge. The pins are sometimes called "contacts" and are arranged in groups of up to 25. These contacts are designed to be press-fit into a corresponding receptacle and are held in place by an outer bar. This type of connector is designed to provide a reliable and cost-effective way of transferring data between two computers or peripherals.The 5551-19-1 is a specific type of Centronics connector that is used in the parallel port connection. It is a 25 pin version with a 9-pin shell that fits into a standard 9-pin receptacle. This type of Centronics connector is commonly used for ethernet connections, printer connections, and other parallel port applications.The working principle behind this type of Centronics connector is quite simple. When the two sides of the connector are joined, the pins on the outer facing portions are pressed against spring-loaded contacts in the receptacle. This results in an electrical connection that allows data to be transferred from one device to another. This type of connection is also known as a push-pull connection.The 5551-19-1 application field is quite broad, due to its nature of being a plug-and-play connector. It is widely used in computers, gaming consoles, and a variety of peripherals. It is also used in the industrial automation sector, as it provides an easy way to connect input/output devices and control signals.In conclusion, the 5551-19-1 d-shaped Centronics connector is a reliable and cost-effective connection solution that provides a plug-and-play connection. It is widely used in computers, gaming consoles, and other peripherals, as well as a variety of industrial automation applications. The working principle of the connector involves pushing the pins of the connector against spring-loaded contacts of the receptacle, which results in the transfer of data.
