Can you remember? Bob and Mary Jane Engman can—they were in their house in Huntington Beach, California, planning a new company to manufacture the optically isolated, liquid epoxy-filled solid-state relays that Bob had drawn the design for at the kitchen table. That's Bob in the photo at the right.
This new manufacturing process made SSRs both more reliable and cheaper to build than others on the market. Better for customers. Better for business.
Bob and Mary Jane called their new company Optrol at first, but that name was already used by another company. So they chose Opto 22.
