We are TOCOS AMERICA, INC.

Headquartered in Schaumburg, Illinois since 1984, we are a fully owned subsidiary of Tokyo Cosmos Electric Co., Ltd., a global provider of electronic components. Originally established in 1957 and publicly traded on the Tokyo Stock Exchange, TOCOS began as a manufacturer focused on high-quality variable resistors for industrial use.

Over the years, we have steadily expanded our range of variable resistors (potentiometers), initiated large-scale production of angle sensors for automotive electrical systems in 1976, and, in 2016, commenced manufacturing automotive film heaters used in advanced driver-assistance systems (ADAS) for enhanced safety

By diversifying our range of manufacturing products, we have grown in step with the advancement of the electronics industry across sectors such as electronic devices, transportation systems, industrial machinery, and more. Building on our core expertise in variable resistor manufacturing, we have broadened our business scope to include related technologies and product domains.

ISO Certification

TOCOS products are manufactured by our parent company Tokyo Cosmos Electric Co. in ISO 9001 and ISO 14001 certified facilities.

Design & Manufacturing

The in-house design and manufacturing of automatic assembly machines and automatic testing and inspection equipment guarantees efficient, quality component production.

Research & Development

The continuing technological demand for products with higher accuracy, longer life, and better reliability has led us to utilize the ingenuity of all our employees through an innovative “think and create” philosophy, encouraging company wide contributions to product research and development.

Quality Control & Reliability

Our “total quality control environment” is supported by a start to finish inspection program that guarantees just-in-time delivery. Every workstation is an inspection point in the manufacturing process and the finished products are always inspected for electrical and mechanical properties as well as environmental reliability. TOCOS examines the performance of its products long after their sale, through the widely used FIT, or failure rate in the field methodology. We at TOCOS are committed to the bright future of technological progress in the 21st century.
