Brand Introduction
CUI Devices is an electronic components manufacturer specializing in an ever-expanding range of product technologies. Formerly part of CUI Inc, you can trace our roots back to 1989 just outside of Portland, Oregon. In September of 2019, a group of senior managers deeply involved in the historical growth of CUI Inc—and with over 15 years of average tenure—spun-off part of the business. Thus, CUI Devices was born, offering a wide range of Interconnect, Audio, Thermal Management, Motion, and Sensor solutions.
