Rectangular Connectors - Headers, Receptacles, Female Sockets are among the most commonly used connectors in electronic market today. The 71991-309 series is one of the widely used configuration due to its versatile design that is suitable in a wide range of applications. This section will focus on the application fields and working principle of the 71991-309 series.

The 71991-309 series has a 2.54mm centerline pitch. These connectors are preferred by engineers and manufacturers due to its large contact arrays which allow them to suit large commissioning needs. Additionally, the square-wave contact type of the connections ensure stable performance under high frequency circuits. This type of connector is used in a variety of applications such as LED lighting, audio equipment and robotics applications.

The 71991-309 series has a durable construction which makes it highly resistant to shock or vibration. This ensures reliable performance even in tough environments. Furthermore, these connectors have an improved PCB retention making them more robust compared to other connectors. The connectors have an extended temperature range from -25°C to +105°C hence allowing them to be used in a variety of applications ranging from automotive to consumer applications.

The working principle of the 71991-309 series is similar to that of other rectangular connectors in its class. This series has two rows of crimp contacts within its housing. These contacts are pre-assembled within their housings to make handling easier. The contacts will run between two straight rows of electrical circuits on the PCB board at the same elevation. The contact points connect the circuits together in pairs when the electrical power is sent through them. The mating connectors are also pre-crimp which ensures a secure connection with the housing.

The 71991-309 series is also designed to ensure easy installation and assembly. The connectors have an easy-to-read label that allows them to be identified quickly and easily. The connector’s threaded fastening can also be adjusted to meet various applications such as in ground containment and elevated containment. They also have a removable locking collar to ensure tight contact connection.

In conclusion, the 71991-309 series is a highly flexible and versatile connector suitable in a wide range of applications. It has a durable and robust construction which makes it suitable in demanding environments. Additionally, the quick and easy installation and assembly makes it very popular among engineers and manufacturers. With its large contact arrays, it is able to suit large commissioning needs and thus provides great value for money.
