ARINC backplane connectors are used to connect one electrical system to another. The connectors have pin-out variations designed to facilitate the connection of several different types of electrical systems. The 21342-4 backplane connector is one of the most popular ARINC connector types. This article provides an overview of the 21342-4 connector’s applications and workings.

Application Fields for 21342-4 Backplane Connectors

The 21342-4 connector has a broad range of uses in aerospace, industrial, and communications applications. In aviation, the 21342-4 is commonly used in radar systems, navigation systems, instrument panels, and aircraft avionics. The connector is also found in surveillance and security systems, as well as in air traffic control systems.

Additionally, the 21342-4 is employed in military combat systems, such as communication systems, navigation systems, and defense systems. It is also used in flight test and missile systems. In industrial settings, the 21342-4 connector is helpful in controlling computer-aided machinery.

Advantages of Using the 21342-4 Backplane Connector

The main advantage of the 21342-4 connector is its durability. It features metal shells with a deep thread for extra mechanical strength and robustness. The connector is resistant to corrosion and debris, making it suitable for harsh environments. The outer shell of the 21342-4 also provides protection against tampering and physical shock. Additionally, the 21342-4 is designed to hold up to 2-5mm cables, which makes it especially useful for applications that require peace-of-mind wiring and the transmission of high power.

The 21342-4 connector also facilitates the high-speed transmission of data. Thanks to its signal integrity shielding, the connector ensures a low bit-error-rate (BER) and can handle many different signal standards. It is also suitable for environments that have high levels of electromagnetic radiation and vibration. As a result, the 21342-4 can be used in the most demanding applications.

Working Principle of the 21342-4 Connector

The 21342-4 connector is a contact-based electrical connection system. It consists of an insulating rubber gasket, two mating mates, and three specifically designed center contacts. The contact sizes on the connector are designed to ensure that there is proper contact with their mating base. To ensure that the 21342-4 connector is securely coupled to its mating pair, two latching mechanisms are provided, one of which is an embedded keyway in the connector’s mating base.

The three center contacts of the 21342-4 connector are designed to provide electrical and mechanical interconnection between two different systems. The contacts provide power, signal, and control functions. Additionally, the 21342-4 connector is capable of providing maximum performance over a wide temperature range.

In addition to the latch, the 21342-4 also includes a dust cap that can be fitted over the connector’s mating base to ensure that the contacts remain clean and dust-free. The dust cap also ensures that the mating pins are properly mated and that no other objects are present in the mating base.

Conclusion

The ARINC 21342-4 backplane connector is an indispensable component in a variety of applications, from aerospace and military to industrial and communications. The connector’s durability and robustness make it suitable for harsh environments, and its signal integrity shielding ensures high-speed data transmission with low bit-error-rates. Moreover, the 21342-4 connector’s two latching mechanisms and dust cap provide secure coupling and protection against dust and debris. As such, the 21342-4 connector is an essential component in a wide range of applications.
