Opto 22 was founded in 1974 by engineers who designed a better solid-state relay and chose to build it in a non-corporate, flat organization. Over 30 years later, we’re still privately held, lean, and run by engineers.
Our flat organization fosters individual responsibility, quick response to customers’ needs, and fast development of cutting-edge products. Teamwork and enthusiasm mark new product development.
Our engineering focus shows in the quality and reliability of our hardware. All our products are manufactured at our headquarters in Temecula, California. Each hardware item is individually tested, and most I/O modules are guaranteed for life.
Customers comment about their dusty, 20-year-old “Optos” still doing the job in the back of a factory somewhere. With this kind of quality, we can afford to provide free customer service with every product.
