CONESYS EUROPE

What CONESYS EUROPE does

Conesys Europe is a French manufacturer of circular interconnection connectors and hermetic connector solutions, headquartered in Colomiers (Toulouse metropolitan area) since the inauguration of its current site in 2006. The company was established in 1997 as the French branch of AERO ELECTRIC CONNECTOR INC. and became a standalone French entity (SASU) in 2001 upon the formation of CONESYS Group, a US parent formed from the merger of AERO ELECTRIC CONNECTOR, J-TECH, and EMP Connectors. Conesys Europe operates as a wholly-owned subsidiary of that group, alongside EMP Connectors in Torrance, California, which provides EMI/EMP filtered connector solutions for the group portfolio. The company serves aerospace, defense, energy, transport, and industrial customers across more than 40 countries.

The company's core technology is proprietary glass-to-metal sealing, comprising four specialized sealing variants (compression, matched, low-temperature, and special) that deliver leak rates below 1·10⁻⁹ atm·cm³·s⁻¹, temperature resistance to 350°C, and pressure tolerance above 2000 bars. This is the basis for a product portfolio split between hermetic glass-sealed connectors (qualified to MIL-DTL-38999 Series III, EN2997, and related standards) and standard/modified environmental connectors (MIL-DTL-5015, MIL-DTL-26500, MIL-DTL-26482, MIL-DTL-83723). The 2018-patented Hermoptic® technology extends the hermetic line into fiber optic applications (vacuum, pyrotechnic, fuel gaging, on-board cameras). The product stack is backed by EN9100, ISO9001, DLA MIL-DTL, and ASD-CERT EN2997 certifications, plus Airbus normative-standard supplier qualification and VAD C-Class assembler status for major MIL connector families.

Commercially, Conesys Europe operates a B2B direct-sales model with no public pricing — connectors are quote-based, built to customer specifications against MIL/EN normative standards or custom designs, and sold through a website-mediated consultation process for technical and commercial inquiries. The company markets through its corporate website, participation in industry trade shows (notably ADIPEC for the Oil & Gas sector), and membership in French aerospace associations (Aerospace Valley, GIPI, Space Aero, SPACE). Revenue is not disclosed; legal-form and capital structure indicate a focused single-site SME operating within the broader CONESYS Group rather than a large standalone manufacturer. Named customers include Airbus (qualified since 2008) and First Light Imaging (scientific instrumentation, adaptive optics).
