ARINC - Backplane Connectors

Backplane connectors provide communication between various modules or components within a larger system. ARINC (Aeronautical Radio Incorporated) is a specialized, open-architecture bus used mainly in avionics applications. These connectors are used in the designs of high-speed, high-reliability multi-function modules to be utilized in flight-safety related applications. The ARINC-649 type connectors, commonly known as ARINC-649, are a type of high-performance aerospace backplane bus.

The ARINC-649 Connector

The ARINC-649 connector combines the medium differential voltage interface standard (MIL-STD-1553) with an extensive, linear bus layout to provide an efficient data transfer within the system. The connector is a low-level interface, designed for data transfer rates of up to 400 Mbps. The connector includes up to 16 differential signal pairs and two common signals.

ARINC-649 working principle

ARINC-649 is based on the principles of bus arbitration. This means that when two modules need to communicate, the bus system first evaluates the situation and decides which one has the highest priority, before allowing the data to be transmitted. This arbitration allows multiple modules to access the bus without conflicting with each other. The speed of data transfer is dynamic, and depends on the type of data being transferred as well as the current state of the bus.

Application fields

ARINC-649 connectors are mostly used in military applications, such as aircrafts and drones. The military relies on this backplane bus to transmit and receive data quickly and efficiently. The applications include navigation, navigation updates, flight management systems, mission processors, electronic flight instrument systems, and other avionics systems.Another application of the ARINC-649 connector is in automotive applications. Many vehicles use the ARINC-649 connector to collect data and communicate with other systems. This includes brake systems, fuel systems, pumps, and air conditioning. With the automotive industry’s push towards connected cars, the need for reliable backplane connectors is increasing.In addition, the ARINC-649 connector is also used in industrial automation and robotics. It is used to control robotic arms, 3D printers, and other precision machinery. The connector is also used to synchronize distributed systems, such as those used in industrial manufacturing facilities.

Conclusion

The ARINC-649 connector is a specialized, open-architecture bus developed for avionics applications. This backplane bus provides reliable, high-performance data transfer between multiple modules or components. Its arbitration mechanism allows the system to prioritize data transfer requests without conflicting with each other. The ARINC-649 connector is used mainly in aerospace, automotive, and industrial automation applications.
