CUI Devices

CUI Devices is an electronic components manufacturer specialising in an ever-expanding range of product technologies. Formerly part of CUI Inc, you can trace their 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.
