What Connectronics does

Connectronics Corp. is a privately held U.S. specialty manufacturer founded in 1988 and headquartered in Toledo, Ohio. The company designs and builds custom electrical connectors, cable assemblies, wire harnesses, and high-voltage lead wires for applications where failure is not an option. Core product lines span high-voltage connectors rated 5–60 kV (CMC-715, MIDGI, SCID, HVL, RMP series), high-current connectors rated 200–1,000 amps (Flash Lamp and Safety Lock series), underwater connectors (UWC series) rated to 300 VDC and 500 PSI, and specialized connectors for nuclear, hermetically sealed, thermocouple (-54°C to +982°C), and vacuum/X-ray environments. Complementary offerings include custom cable assemblies, military cable assemblies compliant with MIL-SPEC, and the Wiremax family of SIL-KOAT silicone-coated FEP and proprietary PFA micro-bend wire products.

The business operates a B2B, custom-engineered model: every project begins with customer consultation and proceeds through design modeling, prototyping, environmental and electrical testing, and production validation, with manufacturing, machining, assembly, and testing performed in-house at the Toledo facility. Pricing is quote-based and tied to project complexity rather than published list price. The company holds AS9100D and ISO 9001:2015 quality certifications and is ITAR registered, enabling participation in U.S. and allied aerospace, defense, medical, nuclear, and marine/subsea supply chains.

Go-to-market is a direct enterprise field-sales motion supported by three U.S. touchpoints (Toledo headquarters, a West Coast office in Morgan Hill, and a Midwest sales office in Helotes) and three international distributors covering Korea (Adamco Industries), Israel (Elimec), and Japan (Ascot Company). Primary customer verticals are aerospace & defense, medical device manufacturers, and military & defense contractors, with secondary exposure to marine/subsea and nuclear/research laboratory applications. Marketing is primarily industrial: a technical website with a product catalog and RFQ portal, Thomasnet listings, and a modest presence on LinkedIn and X.
