D-shaped connectors and their Centronics counterparts are widely used in electronic devices and systems. The D-shaped configuration is typically used when a male connector must fit into a female port and the shape of the connector is a key factor in determining its performance. The D-shaped connector is sometimes referred to as a “snap-fit” or “polarized” connector; and the two variations that are common are the 4-pin and 8-pin connectors.

One of the most popular and widely used versions of the D-shaped connector is the 5555139-2, a 4-pin female connector. The 5555139-2 is shaped similar to the number “2” and is used in a wide variety of different electronic devices and systems. It is typically paired with a corresponding 4-pin male plug, although it can also be used with an 8-pin connector in some applications.

The 5555139-2 is a particularly versatile connector due to its ability to be installed in a variety of configurations. This includes daisy-chained setups, where the female connector is connected to multiple cables in a chain, or multiple 4-pin connectors can be “stacked” on top of each other. The connector also allows for the insertion of a “self-locking” pin at the center, which ensures that the connection is secure and stable.

The use of the 5555139-2 is widespread in the electronics industry, with applications ranging from computer hardware, to consumer electronics, to automotive wiring. It is also a popular connector for the robotics industry, where its ability to handle higher voltage and current makes it ideal for use in controlling servo motors and other robotic systems.

The working principle of the 5555139-2 is fairly simple. When the female connector is plugged into a male plug, the four pins inside the connector are lined up with four corresponding contacts in the male plug. This alignment creates an electrical connection, allowing electrical signals to pass between the two components. This connection can be maintained as long as the pins of the female connector remain firmly seated in the male plug, and no external forces are applied to disrupt the connection.

The 5555139-2 is just one of many D-shaped connectors used in the electronics industry, and its versatility and robustness make it a popular choice for many different applications. Its unique shape and simple working principle makes it easy to install and use, and its ability to handle higher voltage and current makes it a great option for powering robotics and other automated devices.
