Understanding the history, characteristics, uses, and critical role that ARINC 600 connectors will play in influencing aviation technology is crucial as we set out to explore its complexities.
Join us as we delve into the world of aviation connectivity and discover how ARINC 600 connectors have become the cornerstone of communication in the skies.
From their humble beginnings to their cutting-edge innovations, let’s explore the unparalleled reliability and versatility that these connectors bring to the aviation landscape.
What is ARINC 600?
A standard rack and panel connector, ARINC 600 connectors are mostly utilized in avionics applications. Line-replaceable units (LRUs) and racks or cabinets can link mechanically, electrically, and environmentally thanks to this modular packaging standard.
The ARINC 600 connector is a rectangular molded insulator housed in a metal or composite shell. Its numerous forms handle high-speed data, power, signal, and fiber optics (with adaptors) and are equipped with application-specific combinations of contacts. Shells are usually mounted with solder or screws. There are three configurations of ARINC 600 connectors: twinax, coax, and quadrax.
History of ARINC 600
ARINC 600 connections have traveled the globe for almost 40 years. This essential part of contemporary avionics enabled comfort, safety, navigation, communication, and networking features in both commercial and military aircraft, contributing to the dawn of modern air travel and transportation. Certain military ground vehicles are also equipped with ARINC 600 connectors.
The Federal Radio Commission granted ARINC (Aeronautical Radio, Incorporated) a charter in 1929 so that it could act as the exclusive coordinator of radio communication for the airline sector.
Aircraft communications equipment components, such as trays and receptacles for radio units, are governed by standards created by ARINC. Four large airlines owned the company until 2007.
SAE International purchased ARINC’s Industry Activities Division in 2017, which was in charge of standards development initiatives.
The standard is still being updated by the ARINC 600 Working Group to support the high-density, small size, and weight objectives of upcoming aircraft designs. The development of a new standard connector size (size 4) for single-aisle aircraft is presently under way.
AirBorn, Radiall, Carlisle Interconnect Technologies, and TE Connectivity are associate members of the groups that are responsible for facilitating these operations.
Design Notes of ARINC 600
- The ARINC 404 (MIL-C-81659) was replaced by the ARINC 600. The ARINC 400 series is related to databases, data buses, and wiring. An older range used in analog aviation navigation systems was the ARINC 500 series. Twenty-one application-specific subtypes of the 600 series support various systems, software features, test equipment, and communications protocols.
- Mating Cycles: Depending on the manufacturer, ARINC 600 connections are normally made to survive 500–800 low insertion force mating cycles.
- Low-profile modular connectors called spacing ARINC 600 connectors are made to be installed closely together in congested panels and spaces that are limited in size.
- ARINC 600 receptacles are made of alloys, stainless steel, and aluminum. Plastic inserts are possible. Materials have to adhere to RoHS regulations, flammability, optical smoke density, and outgassing specifications.
- The robust performance of ARINC 600 connectors is intended for high-reliability and harsh environment aviation applications. Vibration, shock, high or low temperatures, radiation, rough handling, chemicals, and other external elements are examples of operating conditions. Numerous vendors provide both non-environmental and environmental options. A sealing sleeve to enclose mated connections or silicone or rubber O-ring gaskets between the shell and inserts may be found on a sealed version of this connector.

- Interference Radio-frequency interference (RFI) and electromagnetic interference (EMI) are major issues in aviation environments where a lot of electronic equipment is present. This worry is lessened by the metal used in the shell and ground terminal, and many manufacturers provide improved shielding.
- Some manufacturers offer filtered versions. In certain designs, TVS diodes and planar filter arrays may be merged.
