JEM Electronics

What JEM Electronics does

JEM Electronics is a privately held contract manufacturer founded in 1981 and headquartered in Franklin, Massachusetts, specializing in build-to-print custom cable assemblies, wire harness assemblies, and electromechanical assemblies for OEM customers. The company operates dual manufacturing facilities in Franklin, MA and Tijuana, Mexico, and reports between 51 and 100 employees. Its technical capabilities span continuity, VSWR, hipot, and pull testing; Lean Six Sigma process improvement led by Green Belt-certified staff; and compliance with ISO 9001:2015, IPC-A-620, IPC-J-STD-001, ITAR, and NIST 800-171/CMMC preparedness standards.

The company's core product portfolio includes custom cable assemblies, wire harnesses, and electromechanical assemblies, with specialized offerings in Ethernet (up to 10 Gigabit), fiber optic, coaxial, RF, ribbon, EMI-shielded, twisted pair, Mil-Spec (M22759, M16878, M25038, M13486, M5086), and box build configurations. These products serve seven primary verticals: defense and military, medical and healthcare, robotics and automation, semiconductor, computer networking, renewable energy, and oil and gas. Notable vertical-specific capabilities include Mil-Spec assemblies for aerospace and ground vehicle applications, cable assemblies engineered for millions of bend cycles in industrial robotics, and ruggedized assemblies for high-pressure and high-temperature downhole oil and gas environments.

JEM operates an enterprise field sales go-to-market motion targeting OEM buyers through direct outreach, industry events such as the Design-2-Part Show, and inbound quote requests via the company website. All pricing is custom and quote-based, determined by design complexity, volume, materials, and certification requirements; revenue is generated through project-based manufacturing contracts with no public price list. In December 2021, JEM acquired PGC Wire & Cable to expand manufacturing capacity, and the company has since added a Tijuana facility to provide USMCA-compliant nearshoring for North American customers. Distribution is direct-only with no reseller or marketplace channels, and products ship from the two manufacturing sites to customers across North America, Mexico, and Costa Rica.
