ARINCARINC connectors are a type of backplane connector that is used in aviation and aerospace applications. ARINC stands for "Aeronautical Radio, Inc.", and these connectors were originally developed by the company for use in aircraft communications systems. ARINC connectors are characterized by their high-density pin arrangements, which allow them to carry a large number of signals in a small space. They are also designed to be rugged and reliable, in order to withstand the demanding environments found in aviation and aerospace applications. ARINC connectors are commonly used in a wide range of avionics systems, including navigation, communication, and entertainment systems. They are also used in other applications where a high-density, high-reliability backplane connector is required.
