SIGMA Surplus was born out of a major, yet unaddressed, need in the automation industry. When your production line is down and you’re in need of a hard-to-find or obsolete component, what do you do? Every tick on the clock is potential revenue down the drain, and a long lead time from the original manufacturer only makes it worse. SIGMA Surplus is the solution to that problem. We offer reliable, name-brand automation components for nearly every type of machine in the industry. Our used, new and open-box inventory of more than 100,000 items is coupled with fast, same-day shipping and personalized service to create a one-stop solution for our customers.
