Backplane connectors are used to interconnect circuit boards and create a system assembly. ARINC connectors have been in development since the 1940s for the defense and aerospace industry. The DPXA-57-34P is a Double-Ended High-Speed connector, rated to 10.0 GHz, from the ARINC family of products. In this article, we will discuss the DPXA-57-34P’s application field and working principle.

The DPXA-57-34P backplane connector is designed to provide the highest possible speed and signal integrity in a wire-to-board interconnect. With a 133-Position, double-ended design, it offers outstanding signal integrity from both the differential pair geometry and the short signal paths, while maintaining reliable connection and preventing interference between outputs. This connector is a perfect choice for high-speed applications, including high-speed data transmission, military and aerospace systems, as well as civilian aircraft.

In addition to its performance advantages, the DPXA-57-34P backplane connector has several additional features that make it attractive for engineering applications, including EMI shielding, low-inductance signal paths, and a low-profile design. The EMI shielding allows for protection against external electrical interference, while the low-inductance signal paths reduce crosstalk and EMI noise. The low-profile design also reduces the weight of the connector, making it ideal for applications with limited space and weight restrictions.

The DPXA-57-34P backplane connector is constructed of high-performance materials that are engineered to meet the demands of high-speed military and aerospace applications. The outer housing is constructed from rugged aluminum alloy, and is anodized for improved corrosion resistance and EMI shielding. The contact elements are constructed from platinum plated beryllium-copper, providing increased electrical performance and enhanced resistance to mechanical wear. The contact pins are also constructed from gold plated copper alloy, which provides superior electrical connection without causing corrosion or skin-effect issues.

The DPXA-57-34P is designed to work with a variety of high-speed protocols, such as IEEE1394b, PCI Express, and HDMI. It is capable of providing high-speed data transfer rates of up to 10.0 Gbps, and is designed to minimize crosstalk and EMI noise. The connector is designed with a positive lock system, which ensures that the connection is secure and reliable. Additionally, the connector is designed with a high-integrity terminal, which matches the contact pin pitch and insulation distance of conventional connectors, allowing for compatibility with a wide range of cables and connectors.

In conclusion, the DPXA-57-34P is an ideal choice for high-speed applications in military, aerospace, and civilian aircraft. With its robust design, high-integrity terminal, and EMI shielding, the DPXA-57-34P backplane connector is designed to provide reliable connection, with minimal crosstalk and EMI noise. It is also designed to be lightweight and low-profile, allowing for use in areas with limited space and weight restrictions.
