Backplane Connectors - ARINC 211027-1

ARINC 211027-1 is a specification that applies to backplane connectors used in Avionics. Specifically, it defines the methods and materials for the design, manufacturing, installation and maintenance of backplane connectors intended for high-reliability applications in the aerospace industry. The connectors defined in this specification are sheet metal or molded body receptacles, plug pins, keying plugs, and protective covers. Connectors of this specification have a variety of applications, including use in aircraft, naval vessels, and space vehicles.

Application Field

ARINC 211027-1 connectors can be used in avionics and aerospace applications, including aircraft control systems, navigation systems, communication systems, identification systems, and safety systems. They are designed for harsh environmental conditions, such as extreme temperature, pressure, and vibration. The connectors are also used in air traffic control systems and other rugged applications.

Working Principle

ARINC 211027-1 connectors are designed to provide a reliable electrical connection in very harsh operational conditions. The connectors are usually formed from stainless steel and feature a hermetic seal that prevents moisture and other contaminants from entering. The connectors also have a self-cleaning mechanism, which helps keep the contact free from dust and dirt. The connector provides a secure electrical connection by the use of high-precision pins that fit snugly into matching receptacles. The pins are made from stainless steel and have a low insertion force, which helps reduce the stress that can occur when connecting multiple pins.

The connectors also employ a keying plug which helps ensure the correct connection is made. This plug is color-coded so it is easy to identify the correct type of connector. In addition, the connectors feature a removable protective cover over the pins, which helps protect the pins from environmental elements and accidental damage.

ARINC 211027-1 connectors are designed to last for a long time under harsh conditions. The connectors are tested to stringent requirements and have a high vibration and shock resistance. The connectors also feature a corrosion-resistant coating to help ensure a secure electrical connection over the long term. In addition, the connectors are UL rated, so they meet a variety of safety standards.

Conclusion

ARINC 211027-1 connectors are designed for use in avionics and aerospace systems, and feature a hermetic seal and self-cleaning mechanism to ensure a reliable electrical connection. The connector also employs keying plugs which help ensure the correct connections are made, and incorporate a protective cover to protect the connector from environmental elements and accidental damage. The connectors are UL rated and tested to stringent requirements, and are designed to provide a reliable electrical connection for years of use.
