ARINC Rack and Panel Connectors

ITT CannonARINC Rack and Panel Connectors from ITT’s BKA ARINC 600 connectors for commercial aviation applications provide exceptional versatility, optimum harsh-environment performance, and high reliability in applications including avionics, cabin, and in-flight entertainment and connectivity systems. These high-density, blind-mating interconnects are available in single-, three-, and six-gang configurations with field-replaceable inserts designed to accommodate up to 800 low-insertion-force (LIF) high-speed and ultra-high-speed contacts, including OctoGig™ termini for 10GbE, ARINC-801-compatible fiber optic termini, and multi-signal quadrax contacts capable of up to 2.5Gb/s. The series features rectangular, nickel-plated aluminum alloy shells in several hard- and float-mount receptacle and plug styles with thermoset insulators, copper alloy retaining clips, removable polarizing posts, and various contact options, including front- and rear-release crimp, solder, coax, twinax, triax, quadrax, fiber optic, wire-wrap, and MIL-C-39029 styles (many of which are available in sizes 12, 16, 20, and 22), as well as size 22 stamped PCB contacts that offer significant cost savings over traditional machined contacts. The series also offers power and signal in the same layout and optional waveguide connections, is available in environmental and non-environmental versions, and is rated for 26–6 AWG, 2–46A, up to 300V, 500 mating cycles, and operating temperatures extending from -65°C to +125°C.

TE ConnectivityARINC Rack and Panel Connectors from TE Connectivity’s ARINC 600 receptacles employ a proven stamped and formed contact system with hollow contacts and selective gold-plating on critical contact tines — rather than the traditional, solid, screw-machined, and completely gold-plated contact system utilized by traditional ARINC 600 connectors — to deliver up to 10% weight savings, depending on the insert arrangement, in addition to considerable cost savings. They have single-piece monoblock inserts that simplify the manufacturing process and further reduce costs, are fully intermateable with existing ARINC 600 plug connectors, and deliver excellent electrical performance and reliability equivalent to the standard design in applications including flight control, in-flight entertainment, in-flight network, collision avoidance, and air-to-ground communications systems, as well as in military ground vehicles. The receptacles are currently available in two housing sizes (2 and 3) with high-strength copper alloy solder tail or press-fit power and Quadrax contacts in selectively loaded configurations with up to 150 positions, and with four sizes of power contacts (22, 20, 16, and 12) each rated for 5–23A. They are resistant to shock, vibration, thermal cycling, fluid ingress, and humidity, and are rated for 500 mating cycles in operating temperatures extending from -65°C to +125°C.

Smiths InterconnectARINC Rack and Panel Connectors from Smiths Interconnect’s High-Speed ARINC 600 Series offers a complete line of differential twinax and quadrax connectors and cable assemblies ideal for use in high-speed, matched-impedance, data-on-demand applications in the commercial aerospace and defense industries, including Ethernet, Firewire, Fibre Channel, 100Base-T, and high-speed video hot-links. The series reliably achieves high density, high data throughput (2+Gb/s), and superior signal integrity, maintains signal-to-signal and signal-to-shield characteristic impedance throughout the connector pair, and minimizes jitter and data rate errors. It is available in three shell sizes with cadmium or electroless nickel plating and six standard insert arrangements designed to be fitted with Ethernet-based 100Ω quad contacts, 100Ω or 150Ω matched impedance differential pair contacts, ruggedized expanded beam fiber optic contacts, and concentric triaxial contacts capable of accommodating numerous low-loss twinaxial and concentric triaxial cables in a variety of impedance values. The series also offers custom insert arrangements, anti-rotational cavities, and solder cup, PC tail, and crimp contact terminations.

Cinch Connectivity SolutionsARINC Rack and Panel Connectors from Cinch’ new C-ENX™ Galley Connectors are designed and built to the ARINC 810 standard for use in commercial aerospace galley applications, including beverage makers, ovens, microwaves, refrigerators, chillers, and trash compactors, and are also standardized to BAC and EN4644. They feature stackable nickel-plated aluminum shells that provide weight reductions and mechanical protection and don’t require any additional space for locking and unlocking, modular inserts with interchangeable and intermateable parts that reduce manufacturing and operating costs, spring-floating mounting hardware that compensates for equipment and cabinet misalignment and supports blind mating, centered guide pins and sockets that further support blind mating, and standardized contacts that help ensure timely availability. They can also accommodate six power contacts and 24 signal contacts and can include a twinax connector for CAN data bus connections. In addition, like all C-ENX connectors, the new C-ENX Galley Connectors provide optimized stacking capabilities and space reductions compared to circular connectors, employ the same panel cutouts to reduce rework and complexity, enable field replacement, and require standard mil-spec tools for contact crimping, insertion, and extraction. Further, its C-DMX™ connectors, which are based on BAC, ARINC 809, and EN4165 specifications and designed to minimize size and weight, also provide optimal solutions for commercial aerospace applications, including in-flight entertainment, cabin lighting, and avionics systems. These connectors are easy to install and maintain, require minimal additional tooling, can be wire terminated or PCB mounted, support multiple inserts, including signal, power, data, and fiber, and offer environmental durability, built-in polarization with several keying codes, and EMI protection.
