This week’s Product Roundup highlights connectors used in aerospace from leading suppliers.

Aircraft connectors

SAS/PCIe 4.0 (U.2&U.3) connectors from Amphenol Communications Solutions,SAS/PCIe 4.0 (U.2&U.3) connectors from Amphenol Communications Solutions, used in OLED display applications for in-flight entertainment systems, come with 16 GT/s (PCIe lanes) or 24 Gb/s (SAS lanes) speeds to meet the demands of next-generation servers. The 68-position, SAS/PCIe receptacle and header enables implementation of high-speed Serial Attached SCSI (SAS) hard disk drive (HDD) interface as well as peripheral component interconnect express (PCIe)-based devices. The molded guidepost allows device plug and receptacle to self-align for mating. With halogen-free high temperature thermoplastic, these connectors are made to withstand diverse conditions and offer a durability of 500 mating cycles. They are compatible with SFF8639 specification and are footprint backward compatible to 12G, 6G, and 3G SAS connectors.

Amphenol Pcd’s directional Bluetooth jack Amphenol Pcd’s directional Bluetooth jack adds to or extends the wireless connectivity of in-flight entertainment (IFE) and media systems. The directional antenna allows for a more efficient and less noisy connection compared to a traditional omni-directional antenna. The directional Bluetooth jack provides audio streaming to passenger headphones, headsets, and game controllers via Bluetooth 5.0. It is small, lightweight, and can be installed in the seatback, seat pan, and above passenger seating areas.

AirBorn’s TriMate circular connectorsAirBorn’s TriMate circular connectors have three distinct plug options that mate with common receptacles: a traditional 38999-style ratcheting threaded plug, a push-pull plug for improved density in installations, and a breakaway plug ideal for applications requiring quick de-mating in the field. TriMate’s performance meets or exceeds legacy MIL-DTL-38999 connectors yet are smaller, lighter, and easier –to install. TriMate is used in commercial air applications: general avionics, commercial jets, business jets, urban air mobility (UAM/flying taxis), radar systems, and IFE systems.

LEMO T-Series watertight connectors from PEI-GenesisLEMO T-Series watertight connectors from PEI-Genesis offer durable construction in a package specifically designed for outdoor applications. These rugged push-pull watertight connectors are fitted with an inner sleeve and seals to prevent penetration of solids or liquids, resulting in a protection index of IP68 as per IEC 60529 standard when mated. T-Series offers multiple keyway options to prevent cross-mating. They are ideal for a wide range of rugged environments including airplanes, helicopters, and satellites.

Harwin’s Gecko-MT connectorsHarwin’s Gecko-MT connectors provide the smallest, lightest mixed-technology connector with a lo-profile design, ideally suited for stacking and cable mating in aircraft and other applications where PCB real estate is at a premium. Gecko-GT is vibration- and shock-resistant, miniaturized but with additional 10A contacts.


TRIAXon triaxial contacts designed by Axon’, used for flight control systems, avionics, and space applications, are compatible with standardized connectors, including EN 3545, EN 3645, EN 4135, JN1032, MIL-DTL-38999, ECS0808, ABS2306, ABS1592. Axon’ Triax contacts are crimpable, which makes them more reliable than soldering contacts. Their keying-free mating is fast and reliable. Designed to meet the challenges of mission-critical applications, TRIAXon contacts resist temperatures up to +200 °C.

HBB Series high-power, quick-release harsh-environment connectors from Smiths InterconnectHBB Series high-power, quick-release harsh-environment connectors from Smiths Interconnect are available in both single and five pole versions. The series has a compact robust RoHS design in a metal shell with polarization, user-friendly push-lock mating, and quick-release unmating mechanisms. Sealed IPx7 and IP6K9K when mated, high-reliability Hypertac hyperboloid contacts are rated for up to 500A and have 360º shielding. HBB Series connectors are ideal for air and ground combat vehicles.

Powell Electronics supplies Glenair’s Series 80 Mighty Mouse connectorPowell Electronics supplies Glenair’s Series 80 Mighty Mouse connector, designed for high-reliability commercial and aerospace/defense interconnect applications that require both robust environmental/EMI performance and reduced size and weight. The Series 80 Mighty Mouse connector offers comparable performance to MIL-DTL-38999 Series interconnects with up to 71% weight savings and 52% size reduction for similar contact layouts. The six versions of the product offer a variety of styles and features to suit just about any application.

Nicomatic’s CMM connectorsNicomatic’s CMM connectors are designed to meet or exceed electrical and mechanical performances of MIL-DTL-55302F and BS-9525-F0033 standards. This modular connector allows more than 20 million arrangements with board-to-board, board-to-wire, and wire-to-wire configurations. CMM offers space-saving up to 60% and weight saving up to 50% compared to other rectangular micro-connectors with the same functionalities. It is used in a variety of aircraft applications, including in-flight entertainment and connectivity (IFEC), cockpit, radars, monitoring systems, control systems, panels and displays, engine control systems (FADEC), flight actuators, braking and landing systems, power transmission systems, APU, and cabin interiors and seats.
