Here, we take a look at the 1996220-2 to understand its application field and working principle.

Application Field

ARINC\'s 1996220-2 is specifically designed for avionics applications. Its non-magnetic design helps provide optimal performance, free from interference that can occur through magnetic components. In an ever-evolving aviation industry, where speed and reliability are vital parameters, the 1996220-2 allows for quick, reliable connections. The 1996220-2 is suitable for a wide range of avionics applications, including military, commercial, and civil aviation. These standard connectors are highly reliable and consistent, making them essential for many avionic systems.

Working Principle

ARINC\'s 1996220-2 backplane connector is a two-part device, consisting of an integral shell connector and an encapsulated contact guide. The connector comes in an identical form and can be configured with either a female or male interface, depending on the application. The integral shell connector is made from an aluminum housing, and it houses the contacts inside, helping prevent any movement or potential contact misalignment. The contact guide helps the connector interface with complementary components but also provides protection to the electrical components. The inner layers of 1996220-2 backplane connector require insulation from each other as well as from the external environment, which is provided by the integrated spacing and insulation materials.

The 1996220-2 backplane connector is designed to be used in low power applications, where it is suitable for frequencies up to 100 MHz. The connector is compliant with a range of standards, such as DO-178B/ED compliance. In terms of performance, the ARINC connector is able to achieve an operating temperature range of -55°C to +105°C. The 1996220-2 also features a maximum misalignment angle of 5°, a contact life of 500 mating cycles, and a contact resistance of 10mΩ maximum.

Conclusion

ARINC\'s 1996220-2 backplane connector is designed to provide reliable, secure connections for low-power avionics applications. The two-part connector consists of a shell and contact guide and helps prevent contact misalignments. Its non-magnetic design further allows for a reliable connection free from interference. The 1996220-2 is suitable for military, civil, and commercial aviation applications, as well as other avionics systems, and is compliant with DO-178B/ED. In terms of performance, the 1996220-2 can achieve an operating temperature range of -55°C to +105°C, contact life of 500 mating cycles, and contact resistance of 10mΩ maximum.
