Since Automation Components, Inc. formed back in 1991, we have challenged ourselves to manufacture high quality products sourced locally and made right here in the U.S.A. We take pride in employing over 160 employees in our manufacturing facilities here in Middleton, WI (where we have been since 1991). As demand for our “Made in America” products continued to grow, ACI expanded both our manufacturing facilities and our product lines, bringing jobs that were originally sourced overseas back home to our very own state-of-the-art facilities. Typically companies will source material from overseas, but ACI works hard to source our material not only within our country’s borders, but from within the state of WI as well.


Our commitment to create top-quality products here in the U.S.A. also led to ACI becoming ISO9001 Certified in 2013. This means our products and services remain consistent, efficient, and productive in order to give you the best available service from a company based here in the U.S. At ACI, we raise the bar for it means to be “Made in the U.S.A.” and we will continue to commit to manufacturing our products right here in America.

Automation Components, Inc. (ACI) is a manufacturer and distributor of sensors for the Heating, Ventilation, and Air Conditioning (HVAC) Industry. ACI was founded in 1991 and is located in Middleton, Wisconsin.
