555139-1

Centronics connectors are a type of data connector used in a wide range of computing and electronic devices. They’re typically used for connecting external devices such as printers or scanners. The most common type is the male-female type that mates with a female-male type. The 555139-1 is a specific type of Centronics connector, and is also referred to as a D-Shaped connector, due to its unusual silhouette. D-Shaped connectors are usually used to connect devices that have low pin counts, or to allow for a compact connection.

The 555139-1 connectors are used in a variety of applications, including:

• Printers and scanners
• Video projectors
• Computer terminals
• Joysticks
• Thermal printer connectors
• High speed serial data communication
• Computer game ports

The 555139-1 connector is characterized by its simple yet functional design. It features two rows of eight pins each, for a total of 16 pins in all. The pins have a gold-plated finish to ensure optimal performance and reduce signal loss. The connector is also designed to be extremely reliable and durable. It is enclosed in a housing for extra protection, making it resistant to dust and debris. Additionally, it features pressure-latching which ensures a good connection.

The working principle is simple, though intricate in its design. The pins on the connector are surrounded by insulation, and are connected to the device or cable in alternating configurations. When the connector is inserted into its port, the insulation lines up perfectly and the current flows along the pins in a specific order. This helps to ensure that signals are sent and received correctly.

Overall, the 555139-1 is an important and useful type of D-Shaped connector that can be used in a wide variety of applications. It is reliable and durable, and its simple yet effective design makes it an ideal choice for connecting devices that require low pin counts. Additionally, its pressure latching ensures a secure connection and helps protect against signal loss, making it a great choice for more demanding applications as well.
