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.

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...

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

Encoder output choices for best performance and signal integrity

Motion control applications typically require one or more position encoders. Several types are available and the engineer must first decide whether an incremental, absolute, or commutation encoder is most appropriate. After this decision has been made, other selection criteria include resolution and mechanical aspects, such as the mounting pattern and motor shaft size.  By Jason Kelly, Motion Control Design and Applications Engineer, CUI De...

Designing with Peltier modules for precision thermal management

Sometimes cooling needs to be more tightly controlled than a simple heat sink and fan can manage. Rapidly fluctuating loads can make it hard to keep a component at a stable and cool temperature. However, this can often be important when trying to improve signal-to-noise performance or prevent damage to a system. By Bruce Rose, Principal Applications Engineer at CUI Devices
