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.

CUI Devices’ Audio Group today announced the addition of waterproof enclosed speakers to its CES product family. Carrying IP67 ratings, these enclosed speakers feature sound pressure levels (SPLs) from 89 to 106 dB at 10cm and resonance frequencies from 680 to 1,700Hz.
Monitoring, control, and protection options in DC fans
DC fans are called upon by engineers in many situations and applications to provide forced-air convection cooling. Thanks to their widespread use, they are relatively easy to understand and can be implemented in a variety of configurations. By CUI Devices
Driving piezoelectric transducer buzzers
Forming part of the user interface apparatus, piezoelectric transducer buzzers can provide an important function in a broad array of electronic equipment. Through incorporation of one of these electromechanical components, an audible signal can be passed to the equipment’s user. By Ryan Smoot, CUI Devices
Common reliability factors in peltier modules
Gaining more wide-spread use due to their precise temperature control and reliable solid-state construction, Peltier modules or ThermoElectric Coolers (TEC) operate by transferring heat from one side of the module to the other when electrical power is applied. By CUI Devices
USB Type C receptacle for power only applications
CUI Devices’ Interconnect Group has announced the introduction of a new USB Type C connector designed for power only applications. The UJC-HP-3-SMT-TR is a 6-pin USB Type C receptacle that can deliver up to 60W of power with a three amp rated current and 20Vdc rated voltage.
CUI devices prioritises efforts to tackle COVID-19
CUI Devices has announced new initiatives in its support of the medical industry’s response to the global coronavirus (COVID‑19) pandemic. These initiatives include prioritising orders and expediting free product samples to OEMs, makers, volunteers, and organisations designing medical equipment key to fighting COVID‑19, such as respirators, ventilators, blood analysis machines, test equipment, patient monitors, imaging systems, and home...
A closer look at IP ratings and designing with IP rated connectors
If you have owned a portable device, then you have likely subjected it to unwanted dirt or a drop into liquid. From tablets and wearables to outdoor sensors and industrial equipment, the demand for devices that can withstand these host of environmental factors continues to grow. By Ryan Smoot, CUI Devices
Screwless terminal blocks for high temperature operation
CUI Devices’ Interconnect Group has announced the addition of screwless terminal block connectors for high temperature applications. Featuring -40 to +130°C operating temperature ranges, the horizontal orientation TBLH10 350 and TBLH10 500 series as well as the vertical orientation TBLH10V 350 and TBLH10V 500 series provide a rugged solution for wire-to-board application dealing with extreme temperatures.
Choosing the right rotary encoder for ruggedness and performance
The motion control systems of equipment such as industrial automation or robotics are often reliant on rotary encoders to provide data on position, speed, direction and distance. These typically feature a disc, which is attached to the shaft of the motor whose movements need to be tracked. By Jeff Smoot, CUI Devices
Senior managers purchase CUI Inc’s Electronic Components
Former senior managers of CUI Inc announced that they have purchased the company’s components business from CUI Inc’s publicly-traded parent company, CUI Global. The newly-formed private entity will go to market as CUI Devices and will continue to serve its customers and develop new technologies within its interconnect, audio, thermal management, motion and sensors product lines.
Capacitive incremental encoder supports increased shaft sizes
CUI Devices have announced the addition of a new series to its innovative AMT incremental encoder family to support larger motor shaft sizes from nine to 15.875 mm. The AMT13 series, based on CUI Devices' proprietary capacitive ASIC technology, brings the same high levels of durability, accuracy, and immunity to environmental particulates as current AMT encoder models.
How to achieve temperature control with a peltier module system
A Peltier module, also known as a thermoelectric module, is a powerful device for thermal management, for use in applications such as laser products. When a current is passed through the module a temperature differential is created, causing one side to be hot while the other is cold. Depending on the design of the module and the applied voltage and current, a temperature differential over 100°C can be achieved. By Bruce Rose, Principal Appli...
Beamforming arrays with MEMS microphones
Offering small size, low power consumption and affordability, MEMS microphones are chosen by designers for a wide variety of applications including tablets, desktop computers, headsets and teleconferencing terminals, as well as specialist equipment such as environmental noise monitors and equipment for surveillance and law enforcement.

Considering the trade offs of different fan bearing designs
Fans are a vital element of many electronic systems, designed to keep the device operating within recommended temperatures, while making sure the electronics are working at their optimum level. Attempts have been made to find alternative thermal management methods, with none proving as effective and economical as the fan. By Ryan Smoot, CUI Devices
Understanding the encoder resolution
An incremental rotary encoder can be used to measure rotational direction, speed and angular displacement. The encoder generates two output channels as it rotates, A and B. Each output is a square wave, and in a quadrature encoder, the two outputs are 90° out of phase. By Jason Kelly, Motion Control Design and Applications Engineer, CUI Devices
