ARINC connector is a type of backplane connector used to provide electrical connections between two or more electrical tracks on a printed circuit board (PCB). This type of connector was developed in 1970s by Aeronautical Radio Incorporated (ARINC), an American aircraft manufacturing company. The ARINC connector has become a popular choice for many applications due to its ruggedness, wide variety of sizes, simple cable attachment, and cost effectiveness.

The ARINC connector has a special feature compared to other connectors. It allows data transmission between multiple boards by means of a connector interface. This type of connector can be used to transmit analogue or digital signals. The ARINC connector is also capable of very high-speed transmission rates, providing up to 1,000 feet of cable length. Additionally, the connector is designed to provide a reliable, ultra-high frequency connection, enabling extremely fast data transfer rates.

The ARINC 494131-2 connector is a popular choice for rugged backplane applications. This type of connector is designed to be used in harsh environments as they have a built-in rating of 240°C, allowing them to perform reliably in temperatures ranging from -70°C to +125°C. Furthermore, the ARINC 494131-2 connector is UL listed and meets the requirements of MIL-PRF-22885B. This makes it suitable for use in aerospace applications such as aircrafts and military vehicles.

The ARINC 494131-2 connector consists of two parts; the plug and the receptacle. The plug features a single row of high-reliability gold-plated contacts. The receptacle has two rows of high-reliability gold-plated contacts that are optimized for secure mating and high-frequency signal transfer. When mated, the plug inserts into the receptacle. This is achieved using a locking mechanism similar to most other ARINC connectors. This locking mechanism is designed to ensure a secure connection regardless of vibration and shock. Furthermore, the plug and receptacle also feature solder tails for easy soldering to the PCB.

The ARINC 494131-2 connector is widely used in applications that require reliable backplane connections, such as aerospace, automotive, and industrial applications. This type of connector is also ideal for applications requiring high-speed data transfer rates, as it has been tested to provide data rates of up to 1,000 feet per second. Its large variety of sizes make it suitable for a range of applications, and its simple cable attachment provides easier and quicker assembly times. The combination of these features make the ARINC 494131-2 connector an ideal choice for a range of backplane connector applications.
