The ARINC (Aeronautical Radio Inc) backplane connectors are designed to satisfy the need for a reliable interconnection between devices. The ARINC specifiers and designers have made sure that the solutions are able to provide an effective solution to the high speed and the continuously changing nature of data signals used in the avionics industry. It is critical that the ARINC connectors meet the high speed requirements since the data signals typically move in nanoseconds.

The ARINC family includes a wide variety of connectors ranging from simple bus interfaces to complex, high-performance, application specific connectors. ARINC connectors also have a wide range of form factors, ranging from tactile buttons to plug-in or snap-in connectors. In terms of ARINC application field, they are generally used in data communication applications, providing high-frequency, high-speed communication between two or more modules in a system.

Due to their unique characteristics, backplane connectors are the ideal solutions for many applications, including aircraft interconnection systems, test and measurement equipment, and instrumentation. In addition, backplane connectors can be used in industrial, automotive, and military electronic applications.

The basic structure and working principle of ARINC backplane connectors is based on a combination of the modular backplane connection technology and the use of specialized connectors. The modular backplane connection technology utilizes a series of pinpoint connections. This arrangement includes one master connector and several secondary connectors. All connectors are mounted on a flat circuit board, which provides an easy and quick connection to the backplane. The secondary connectors are designed to be connected to the master connector, which is then connected to the backplane.

The pins in the master connector establish the required electrical connection between the primary and secondary connectors. The signal lines from the secondary connectors then travel along the backplane and into the appropriate modules. The secondary connectors are designed to facilitate the necessary signal transfers, as well as providing power to the modules. The use of this modular backplane connection technology improves the signal transmission speed and ensures that signals are not connecting with the wrong module.

Moreover, the backplane connectors utilize a specialized connector technology known as differential signaling. This is an advanced form of signal transmission that helps ensure that the signals are transmitted with minimal distortion and interference. This type of connector is highly sensitive and requires special attention to be paid to the manufacturing process.

The ARINC family of backplane connectors has a variety of form factors, but the most popular and highly used are the snap-in and the plug-in connectors. The plug-in connectors use a two-piece design with a pin and an actuator. This design is often optimized to provide a higher density of pins than the snap-in design. The snap-in design is relatively few pins, but has a simple slide-in design and offers durability.

Due to the different form factors available, the ARINC connectors can meet a range of different applications. The plug-in and snap-in form factors are ideal for high-density, small form factor connectors where space is at a premium and faster signal transmission is needed. The tactile buttons for example, are commonly used in switches and buttons, while the plug-in and snap-in connectors are often used in circuit boards.

In conclusion, the ARINC family of backplane connectors offer an effective solution for data communication and noise immunity requirements. With its wide range of form factors and high-speed connection technology, the backplane connectors are well suited to provide a reliable interconnection between modules in an aircraft or other high-end equipment system. Furthermore, the connectors provide a clean and secure connection, which is widely used in aviation for a variety of high-speed data transfer applications.
