Rectangular connectors, also known as headers, male pins, and other names, are an important class of connectors that have a wide range of application fields and working principles, among which the DF3D-9P-2H(20) can be considered the most important.

DF3D-9P-2H(20) is a two-row, vertical mount, plastic rectangular connector, composed of 20 termination pins and a molded body, and has a pitch of 15.24mm between each terminal as well as a current rating of 7.05A per pole. The pins are gold-plated and the body is black thermoplastic to provide exceptional durability and reliability. This particular connector is made to withstand extreme operating conditions, such as temperatures between −40°C and 125°C. Additionally, it is UL94 V-0 approved.

Regarding its use, DF3D-9P-2H(20) is primarily used in applications that require reliable, secure connections such as automation, electronics, energy, lighting, and telecommunications. For instance, they are a primary choice for many communication devices, as they are capable of transferring data securely while providing a simple yet efficient means of connecting. Moreover, DF3D-9P-2H(20) connectors are commonly used to connect and disconnect computers, peripherals, and other electronics. Additionally, these connectors can be used in automotive applications such as for inline fuse blocks, electronic control units, and power distribution systems.

When looking at its working principle, a great feature of rectangular connectors is that each pin is insulated from the adjacent pins, thus providing a reliable connection. Additionally, the contacts are gold-plated, which helps reduce current noise and offers a low resistance connection, enabling high speed and data rates. The connector is also designed for quick assembly and low-profile lines. The pins themselves are held in place by a pair of internal wedges that slide into a groove in the body, providing a secure connection that can be easily released by the press of a finger.

In conclusion, DF3D-9P-2H(20) is a reliable and secure vertical mount rectangular connector that offers a wide range of applications. The gold plated terminals provide excellent resistance and low noise. Additionally, they meet various UL standards and are designed to withstand high temperatures. The quick assembly and low profile lines make them ideal for most modern applications, making them ideal for connecting and disconnecting computers, peripherals, and other electronics.
