Backplane Connectors - ARINC

ARINC, or Avionics Full-Duplex Switched Ethernet, is a sophisticated backplane connector designed for use in avionics applications. The ARINC connector offers superior data paths that are reliable and highly resistant to electromagnetic interference (EMI). The connector\'s design also makes it suitable for any kind of application that requires Ethernet connectivity. Examples of applications include satellite communications systems, aircraft control systems, and aerospace systems.

The BKAD2-244-30001 is a highly reliable backplane connector designed specifically for ARINC applications. This connector has been designed to meet stringent performance specifications and is capable of connecting up to four data lines. It looks visually similar to a standard backplane connector, however the pins on the connector are slightly slanted to ensure reliable contact with the corresponding connectors of the application being used.

Working Principle

The BKAD2-244-30001 backplane connector operates on either an AC or DC voltage. When it is connected to an ARINC application, the connector creates a direct electrical connection between the connected application’s four data lines. A typical data line connection uses four different conductors. The conductor connected to the BKAD2-244-30001’s middle pin is used to transmit data. The other three pins are connected to the remaining three conductors that receive data. When the application is functioning, electric current passes through the four conductors in only one direction, from the transmitting line to the receiving lines.

Once connected, the BKAD2-244-30001 performs a series of tests to ensure the quality of the connection. It checks for shorts, signal integrity, and signal broadcasting. Additionally, every time the transmitting line is activated, the connector checks for sufficient voltage. If the voltage drops below a specific predefined level, the connector will no longer transmit data and will notify the application of an error.

Application Field

The BKAD2-244-30001 is ideal for use in a variety of avionics applications. Due to its small size, the connector can be used in confined spaces where larger connectors would be impractical. The connector is certified for use in Ethernet-based avionics systems, as well as in other applications that require a robust Ethernet connection. Examples of applications that use the connector include aircraft control systems, military aviation radios, missile guidance systems, and satellite communications equipment.

The BKAD2-244-30001 is also suitable for terrestrial applications. Examples of applications that use the connector for terrestrial connections include commercial aircraft systems, rail transport systems, and maritime systems. The connector is also certified for use in hazardous area applications, making it suitable for applications in environments where petrol or gas might be present.

Conclusion

The BKAD2-244-30001 is a reliable backplane connector designed specifically for avionics applications. The connector is capable of connecting up to four data lines and its sophisticated design ensures that the connection is highly secure and resistant to electromagnetic interference. The small size of the connector makes it an ideal fit for confined spaces and its capacity for hazardous area applications makes it suitable for a range of applications.
