Backplane connectors are specialised type of connectors that are used to mount electronic components on or within an electrical subsystem. Therefore, the backplane connectors must withstand the electrical and mechanical requirements of the environment. ARINC 1218049-3 connectors are primarily used in harsh environments such as aerospace, military and transportation applications. They are made to resist high-frequency vibration, temperature cycling, mechanical shock, and various other external environmental effects.

The ARINC 1218049-3 connectors are rectangular in shape and are designed to hold two electrical contact surfaces together. The two contact surfaces can either be insulated or self-mating. The insulation of the contacts minimizes the risk of electrical paths being created and ensures the contacts do not come into contact with one another. The contact points of the connectors are protected from corrosion by means of a hollow, stainless steel shell that is filled with epoxy.

The ARINC 1218049-3 connectors are designed to provide a robust connection that supports high frequencies, shock, and vibration, and maintains a low impedance connection. The unique design of the contact surfaces allows for multiple solder connections to be made simultaneously and the contacts are designed to be extremely stable over time. The solder-in pins can be inserted through the contact surfaces and the legs secured with a locking tab to ensure the connection is secure. The contact spacing of 3.40 mm also ensures that the backplane connector is easy to align and install.

The ARINC 1218049-3 connectors come with a number of features which make them suitable for use in harsh environments. They have low contact resistance and are designed to withstand a higher temperature range which helps reduce the risk of overheating. The connection pins are designed to withstand the high vibration from take-off and landing cycles. The contacts are designed to withstand water, dust and salt spray to the point of providing watertight sealing for up to 60 seconds. The contact surfaces also come with anti-jamming features to prevent them from sticking together during extreme temperature changes.

The ARINC 1218049-3 connectors are designed to provide a reliable connection and address the most demanding requirements of the aerospace, military, transportation and other extreme environment applications. The unique features of the connector make them resistant to external environmental effects, while providing reliable, consistent performance. The contacts are designed to maintain a low contact resistance after the solder-in pins are inserted, and the contact areas are designed to withstand high-frequency vibration, temperature cycling, mechanical shock and other external environmental conditions.
