446660-2

Backplane connectors utilize some form of physical contact between multiple electrically adjacent electronic components or lines, typically providing high-density connections in extremely limited spaces. An ARINC insert is a specific type of backplane connector that allows for both monolithic and multi-tiered connections, and is used for applications that require extreme levels of reliability such as avionic systems. ARINC inserts are primarily available in two form factors, 446660-2 and 446660–3, and each offers a set of unique features and characteristics.

The 446660-2 ARINC insert is a single row of up to 81 symmetric-pair contacts, arranged in a mezzanine configuration. This type of connector is designed to enable the insertion of two contact elements into a single low-profile connection slot, and is most commonly used with flat or flexible circuits. The 446660-2 provides multi-tiered or multi-row mates with up to 8 arrays, and it has a wide frequency range, occupying minimal real estate and delivering exceptional performance. This type of connector is typically employed in high-frequency systems, such as AESA radars, as well as applications such as military, aerospace, medical, communication, and instrumentation.

The working principle of the 446660-2 ARINC insert is based on the use of spring-loaded contact elements that are inserted into the mated circuit boards. These contact elements are actuated by a small lever, which then allows for the extremely high-density connections found in these connectors. A benefit of the 446660-2 design is that by decreasing the space necessary to mate two circuits, the wiring between them can be reduced. This can save valuable space and thus reduce costs associated with the circuit design.

Because of its extremely high reliability and extreme environmental resistance, the 446660-2 ARINC insert is an optimal choice for mission-critical applications in the avionics industry. Its extreme frequency range, robust construction, and ultra-low profile make it an excellent choice for applications demanding reliable high-speed interconnectivity. Additionally, 446660-2 connectors are compliant with a variety of standards, including MIL-STD-845, IEC 601-G, and RTCA/DO-160, that are frequently found in commercial avionic systems.

In summary, the 446660-2 ARINC insert is a backplane connector that is designed for multi-tiered and multi-row mating systems. It is optimized for high-frequency applications, delivering exceptional performance in minimal real estate. The 446660-2 is reliable and proven in the avionics industry, as evidenced by its compliances with multiple industry standards. This is the ideal choice for mission-critical applications, as the 446660-2 offers reliable connection for extreme environments.
