The 71661-5050 D-shaped connector, also known as the Centronics type connector, is a type of electrical connector most commonly used for data and communication signals in computer and consumer electronics systems.

The 71661-5050 D-shaped connector is characterized by having two rows of two or three contacts on each side, with a crimp feature in the center to secure the contacts. The pins are typically small, colored in light gray or gold and may be press-fit or soldered into a circuit board. The D-shaped connector can be found on the back of most computer peripherals such as modems, printers, mice and joysticks.

One of the main advantages of using a D-shaped connector is that it allows multiple connections to be made to a single device without having to use multiple connectors for multiple connections. Additionally, D-shaped connectors are generally smaller than other types of connectors, allowing for easier cable management and improved access to the equipment.

The 71661-5050 D-shaped connector is designed to be connected to a computer’s serial port using a COM port adapter. These adapters are either sold with devices or can be purchased separately. Once the adapter is connected to the computer’s serial port, the D-shaped connector can be inserted into the adapter and securely snapped into place.

At the base of the 71661-5050 D-shaped connector is a ferrite bead filter. This filter helps to reduce noise and interference that can cause errors in the signal, improving the performance of the device. The ferrite bead filters out high-frequency components of the signal while generally allowing low-frequency components to pass through without alteration.

The 71661-5050 D-shaped connector also has a metal strain relief to provide additional protection from mechanical shock. This strain relief helps to ensure that the connector’s contacts remain in secure contact with the equipment while reducing the risk of damaging the connector or its contacts. Furthermore, the strain relief helps to reduce the risk of the connector being pulled from the device due to excessive force.

In summary, the 71661-5050 D-shaped connector is a small and efficient electrical connector that is used for data and communication signals in many computer and consumer electronics systems. It is designed with two rows of contacts on each side for improved connectivity and also has a ferrite bead filter and metal strain relief for improved signal quality and durability. The D-shaped connector can be connected to a computer’s serial port using an appropriate adapter and is a popular choice for a variety of systems due to its small size, easy installation and reliability.
