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.

We save clients money with reliable discounted products and we help them save time by getting them genuine, name-brand parts as fast as possible.

SIGMA Surplus is proud to stand against manufacturing waste. We work to breathe new life into old or obsolete products; automation components belong on your production line, not in a landfill.
