Connectors Companies

Amphenol Space

Wallingford, United States commercial

Amphenol Aerospace is a leading global supplier of space-qualified interconnect solutions, delivering hermetically sealed connectors, high-speed fiber optics, and ruggedized cable assemblies engineered for the extremely harsh environment of space. Aerospace engineers have relied on Amphenol connectors for everything from low-Earth orbit satellites enabling modern communications to the International Space Station and deep space exploration missions. The company's SpaceVPX connector family is specifically designed for space-based electronic systems, leveraging VITA 78 OpenVPX architecture and technology with rigorous testing for extreme space environments including radiation exposure. The Deep Space 38999 series addresses the frigid temperatures of space and extreme cold-weather environments, perfectly suited for below-zero applications where satellites and space vehicles experience temperature swings from 125 degrees Celsius to minus 65 degrees Celsius during orbital operations. Amphenol's Series Five connector represents the next evolutionary step in combining traditional 38999 capabilities in a lighter, smaller package, delivering D38999 performance while being 20% smaller and 50% lighter. High-speed solutions combine the company's extensive legacy of Mil-Spec connectors with cutting-edge technology, supporting data rates up to 56 Gbps in lightweight, aluminum MIL-DTL-38999 shells for demanding bandwidth requirements. Space-qualified connectors must withstand intense vibrations during liftoff and remain mated under rapid acceleration exceeding 17,000 mph when leaving Earth's atmosphere, as demonstrated on NASA's Artemis missions. Amphenol's extensive product portfolio includes cylindrical, rectangular, fiber optic, and high-speed connectors, plus EMI/EMP filters and specialized interconnect systems. The company continues advancing interconnect technology for next-generation satellites, lunar missions, and space launch systems from their manufacturing facilities worldwide.

Heico Space

Hollywood, United States commercial

HEICO Corporation (NYSE: HEI, HEI.A) has evolved from a small aerospace components manufacturer into one of the most successful growth stories in the aerospace and defense industry, with significant contributions to space technology through its Electronic Technologies Group. Headquartered in Hollywood, Florida, HEICO designs, manufactures, and distributes critical components and systems for aviation, defense, space, medical, and telecommunications applications. The company operates through two main segments: the Flight Support Group (FSG), which produces FAA-approved jet engine and aircraft component replacement parts, and the Electronic Technologies Group (ETG), which manufactures high-reliability electronic components for mission-critical applications. For space applications, ETG produces precision-engineered subcomponents and subsystems that support satellite systems, launch vehicles, and ground-based space infrastructure. These components must meet stringent reliability standards for operation in the harsh space environment. HEICO's financial performance reflects its strong market position, with 2024 revenue reaching $3.86 billion—a 30% increase over the prior year. The company has achieved 17 consecutive quarters of net sales growth, with operating income rising 53% for fiscal 2024. Their acquisition-driven growth strategy has brought over 100 companies into the HEICO family, expanding capabilities across aerospace, defense, and space sectors. The company maintains a remarkable track record of 93 consecutive semi-annual dividends since 1979, demonstrating consistent shareholder value creation while investing in advanced technologies for the space industry.

Glenair is a privately held American manufacturer of connectors, cable assemblies and electromechanical hardware, headquartered in Glendale, California, and founded in 1956, when it began making electrical connector backshells and accessories. The company has since grown into one of the larger independent suppliers of ruggedized interconnect products for military, industrial, aerospace and space applications, with additional manufacturing plants in Mansfield (England), Bologna (Italy) and Salem (Germany). Glenair's space-qualified product lines include MIL-DTL-38999 and MIL-DTL-83513 micro-miniature and micro-D circular and rectangular connectors, its Series 806 and Series 89 miniature and nano-miniature connectors, RF multi-port connectors, space-grade wire and cable systems, and ArmorLite shielded cable systems designed to reduce harness weight on spacecraft. It also supplies non-pyrotechnic hold-down-and-release mechanisms (HDRMs) used to secure deployable satellite appendages such as solar arrays and antennas until release, and blind-mate, dead-face and lanyard-release disconnects used in robotic and crewed spacecraft servicing. Glenair states its space products are designed to comply with NASA, ESA and JAXA standards, though the company does not publicly name specific missions or customers for its space hardware. Connectors and wiring harnesses are line items that essentially every satellite and launch-vehicle builder buys rather than manufactures in-house, and Glenair is one of a small number of established suppliers in this niche, alongside Amphenol Space and Heico Space, both already represented in this directory.
