ARINC backplane connectors, also known as ARINC Design Standardization 398 (DS-398), are specially designed for use in airborne computers and white-noise suppression systems. They are designed to meet stringent requirements for reliability, ruggedness, and performance in demanding environments. The ARINC backplane connectors are used to connect data transfer boards, circuit boards, and other system-level components within a system.

The ARINC-398 backplane connectors have a standard format, comprising signal pins, power pins, and ground pins. These pins provide the connection ports for power and data signals to flow between components. The signal pins are arranged in multiple rows and are either functional (active) or spare (inactive). Additionally, power pins use a hybrid combination of rows and columns to provide a reliable and robust connection between components. Ground pins are located between the power pins and are placed between two different signal pins.

The ARINC-398 backplane connectors are designed for use in systems that require ten to twelve signal paths for data transfer. The connectors offer peak operating currents of up to 20 amps and certain models can handle up to 26 amps. This ensures that the requirements of the system can be met in terms of reliable power input to components. The connectors also have enhanced EMI protections, providing improved shielding and dampening levels for RF and EMI environments.

The main functions of the ARINC backplane connectors are to provide a reliable and robust connection for data and power signals between components. The connectors are designed to meet stringent requirements for reliability, ruggedness, and performance in demanding environments. Additionally, the connectors are designed to have enhanced EMI protection, providing improved shielding and dampening levels for RF and EMI environments.

The ARINC-398 backplane connectors are designed to meet the current IT standards and are used in a variety of applications. They are widely used in aerospace electronics and medical instrumentation. Additionally, they can also be used in military equipment and manufacturing applications.

In conclusion, ARINC-398 backplane connectors provide a reliable and robust connection for data and power signals between components. These connectors offer increased EMI protection, as well as peak operating currents of up to 26 amps. The connectors are designed to meet the current IT standards and are used in a variety of applications.
