Backplane Connectors, or ARINC, are a type of connectors that are used to pass electrical signals to and from different parts of a machine. ARINC, which stands for “Attached Receiving Instrument Card Connector,” includes a variety of different types of system-level connectors that are used in different electrical systems, including aerospace applications. ARINC is also known as “Dark Backing Connector” due to its ability to transmit digital and analog signals with minimal electrical interference.

1-211991-2 Application Field

ARINC 1-211991-2 connectors are often used in aerospace application. They offer more than enough power to drive the electronic components in the aircraft or spacecraft. ARINC 1-211991-2 connectors are highly reliable and offer up to 10 amp of current and 45 volts of power. Since the connectors are designed for aerospace applications, they are made with the highest quality materials and are tested to the most stringent standards. This helps ensure that the connectors can resist failure due to environmental or mechanical stresses. Additionally, these connectors make it easier for maintenance personnel to inspect and repair the wiring in an aerospace application.

Working Principle

ARINC 1-211991-2 is a pin and socket type connector that is designed to securely mate two or more connectors in order to pass signals. The connector consists of a pin that protrudes from the back of the connector and is connected to the female sockets in the mating connector. The connector uses two latching systems to hold the connector securely in place. The first system is the friction lock which requires the user to push the male pins into the socket until the connector locks into place. The second system is the cam lock which uses a cam to rotate the pin in the socket and lock it into place.

ARINC 1-211991-2 use a crosswire pin connection method which offers superior electrical and mechanical reliability. This method uses two wires that are crimped onto the back of the connector pins. This creates a very reliable connection and ensures that the signal is properly transmitted. Additionally, ARINC 1-211991-2 can also be used in a two-piece configuration where the pins are soldered onto the terminals of the mating connector before the connector is inserted into the connector. This method is often used in electrical systems such as those found in aircraft.

Advantages

ARINC 1-211991-2 connectors offer a variety of advantages for aerospace applications. The connector provides reliable electrical and mechanical connection, making it ideal for high-powered electronic components in aircraft or spacecraft. Moreover, the connectors can accommodate a wide range of thicknesses for a wide variety of applications. Additionally, the connectors are built to withstand harsh environmental conditions such as dust, dirt, and vibration. Finally, the connectors use a cam lock mechanism that securely locks the connections in place, providing an extra layer of security.

Disadvantages

While ARINC 1-211991-2 connectors provide many advantages, they also have some drawbacks. The connectors are expensive when compared to other types of connectors, and they can be difficult to install. The pin-and-socket design of the connector also requires two different crimping tools for installation. Furthermore, the pins are not as secure as other connector types such as those that employ a snap-lock or bayonet-style connection. Finally, the connectors are not rated for high temperatures or shock, so they may not be suitable for certain aerospace applications.
