A Rich History That Lends Itself to Innovation

The Amerline story begins 40 years ago with powering applications for the military, a highly demanding market we continue to serve. We’ve combined that experience and expertise with industry knowledge to scale up our efforts and support a broader range of industry applications.


Amerline founded.


U.S. Army awards AM General a contract to produce the HMMWV (Humvee). The company goes on to manufacture 250,000 vehicles, with Amerline supporting production of 120 Tactical vehicles a day at peak production.


GTE Airfone gives contract to Amerline Enterprises to supply assemblies placing Airfones in U.S. aircraft. Working in conjunction with FAA specifications, GTE becomes Amerline’s first million-dollar customer.


As business grows, Amerline moves from a 10,000 square-foot facility in Cicero, IL, to a 30,000 square-foot facility in Schiller Park, IL.


Philips Healthcare — a provider of generators, tubes, and other healthcare components, and located in Aurora, IL — names Amerline “Supplier of the Year”, presented for excellence in service.


Oshkosh Defense is awarded the Mine Resistant Ambush Protected (M-ATV) vehicle and the Family of Medium Tactical Vehicles (FMTV) production contracts. Amerline supplies critical Mil-Spec connectors and robust intervehicular cables to power M-ATV trailers (meeting the contractual obligation to produce 1,000 M-ATVs per month ahead of schedule), as well as critical power connectors and value-added products in support of FMTVs.


Defense Logistics Agency adds Amerline to the Approved Manufacturers Part Listing (AMPL) as an approved source for Intervehicular Cable Assembly 7728814 — a robust cable that brings power from the towing vehicle to a trailer.


Miller Electric selects Amerline’s AEC 95234 connector series for new Sub-Arc program.


Amerline’s Quality Management System is registered to ISO 9001:2008 standard.


Lacking a source for a critical connector for the Light Armored Vehicle (LAV) program, the U.S Army selects Amerline Enterprises to develop a VG95234 Straight Plug AEC06E14S-7S-02 (NSN# 5935-01-560-2396). The connector features a custom adapter to install an environmental heat shrink boot.


Defense Logistics Agency approves Amerline for NATO Connector 11682338, making the company only one of three approved to make the NATO Jump-Start power connector. Alongside this success, Amerline responds to a market demand for more availability and shorter lead times.


TACOM (United States Army Tank-automotive and Armaments Command) creates a new National Stock Number for two wiring harnesses Amerline developed for the Flyer Defense Program and supplied to General Dynamics to support U.S. Special Forces.


Amerline’s distribution program begins with Electroshield, located in Yellow Springs, OH.


Amerline expands into supplying AEC connectors and overmolded cable assemblies for overhead sub-transmission electric power equipment. In a process audit of Amerline, G&W Electric notes the presence of excellent processes, extensive documentation, and highly knowledgeable operators, with an audit score of 99.4 out of 100. Amerline currently supplies 11,000+ power cables for this industry annually.
