You can count on high-quality Opto products and continued support for all your automation and IIoT applications.

I have a hard time believing it’s been 50 years since my dad and mom started Opto 22. My dad, Bob Engman, was an engineer who helped develop a better way to manufacture solid state relays. 

SSRs had just been invented in the early 1970s, and the improvement was to pot SSRs with epoxy to protect the electronics from shock, vibration, and environmental contaminants. When Opto 22 began in 1974, our first products were, you guessed it, twenty-two SSR models manufactured by the new method.
