Backplane Connectors - ARINC

ARINC 213434-5 (RADAR) is an extended length type of backplane connector, conforming to the ARINC 600 specifications, with enhanced grounding and shielding capabilities. The 213434-5 standard is most commonly used connector type, and is found in aircraft control, communication, navigation, detection, identification, and display systems. The connector, which finds application in a variety of civilian and military aerospace applications, is designed to provide electrical, optical, and mechanical coupling.

Mechanical Aspects

The ARINC 213434-5 connector is a 52-pin (32-pin numeric and 20-pin letter) male/female, 1-inch deep backplane connector. The connector is available in 19 rows of three pins. The connector is available in two types of configurations; configurable high-density configurations (1 to 8 pins per row) and a fixed-configuration (3 pins per row). The male connector pins are held in place with a robust beryllium copper shell. The pins are held in place by a plastic tang and are designed to ensure electrical and optical continuity when the female portion of the connector is mated. In addition, the connector also includes an integrated ground plane for low noise operation.

Working Principle

The basic principle of operation of the ARINC 213434-5 connectors is that of opto-electrical interference – an ‘optical touch’ between the corresponding pins of both the male and female halves of the connector. The transmission of electricity relies on the physical contact between the two connector halves, which is accomplished when there is sufficient pressure applied to the pins to make electrical contact. The small mechanical pressure applied to the pins causes them to expand, which increases the contact surface between the pins to ensure optimal electrical performance. As the pins expand, they divert any potential electrical interference away from the pins, ensuring that noise does not transfer to or from the device being connected.

Performance Specifications

The ARINC 213434-5 connector is capable of handling frequencies in the range of 10 MHz – 100 MHz, and is designed to meet a number of performance requirements set by the ARINC 600 standard. The connector is also capable of meeting insertion loss, return loss, and crosstalk requirements, as well as requirements related to grounding, and shielding. Additionally, the connector is able to support data transfer rates of up to 1 Gbps.

Applications

ARINC 213434-5 connectors are primarily used in the aerospace industry, and can be found in a variety of aircraft control, communication, navigation, detection, identification, and display systems. The connector is often used to connect various types of sensors and actuators in aircraft. Additionally, the ARINC 213434-5 connector is also used in audio, video, and communication systems, and is commonly used in medical and military applications, as well as in industrial control systems.

Conclusion

The ARINC 213434-5 connector is an extended length type of backplane connector used in a variety of aerospace applications. The connector is designed in accordance with the ARINC 600 standard, and is capable of handling frequencies in the range of 10 MHz – 100 MHz, and data transfer rates of up to 1 Gbps. The connector is robustly designed with a beryllium copper shell and an integrated ground plane for low noise operation. The ARINC 213434-5 connector is a reliable and cost-effective solution for a variety of applications.
