Backplane connectors are accessories that enable the interconnection of groups of printed circuit boards in a given system. The 203839-2 type of backplane connector is one of the most popular due to its affordability and easy installation. This article will explain the application field and working principle of the 203839-2 backplane connectors.

Generally speaking, 203839-2 connectors are used to connect electronic components or printed circuit boards (PCBs) in various electronic devices and systems. It is designed with 40 contacts and 0.6mm x 0.6mm pitch, which makes it a great choice for low to medium-density applications. The 203839-2 connectors are used in a variety of electronic products such as personal computers, industrial control systems, and network communications equipment. Due to its small size, the 203839-2 connector is also suitable for applications where space is at a premium.

In addition to its small size, the 203839-2 connectors are well-suited to specific application fields due to its wide compatibility and flexible design. The contacts are gold over nickel plated for increased reliability and improved conductivity. The contacts are rated to 3 Amps for power applications and miniaturization, making them a great choice for applications with limited space and power requirements. The connectors are also available in an array of configurations, including straight, right-angled, male, female, and board-mount types.

The 203839-2 backplane connectors use a two-piece design that is very simple and efficient. The first portion consists of a male contact that is mounted on a printed circuit board. The second portion is a female contact that is mounted on a different printed circuit board. When both boards are connected, the male contact slides into the female and forms an electrical connection. The two portions are interlocked by four spacer pins located on the female contact. This two-piece design ensures that the connection is secure and protected from any external disturbances.

In addition to its application field and working principle, the 203839-2 backplane connectors also offer an extended mating life, vibration resistance, and a low insertion force. The connectors also feature a high-temperature range of -25⁰C to +85⁰C, making them suitable for high-temperature environments. The connectors also have excellent shock and vibration resistance, which ensures reliable signal transmission.

The 203839-2 backplane connectors offer many advantages for a wide range of applications. With their small size and simple setup, the connectors are an ideal solution for applications with limited space and power requirements. They are also highly reliable and offer an extended mating life and vibration resistance. The connectors are also very affordable and are available in a variety of configurations, making them a great choice for any application.
