Cambridge Mechatronics Announces Ultra-slim, High Precision Rotary Actuator

Cambridge Mechatronics, a leading British company and developer of Shape Memory Alloy (SMA) actuators has developed a new ultra-slim, high precision rotary actuator product. The actuator characteristics include lightweight design, two thousand step positions per revolution and it is completely non-magnetic so it can operate in areas of high magnetic flux that might otherwise exclude conventional motor technologies. With a low profile of around 1mm, it can be used in the most space-constrained applications.

TDK Launches Inductors for Small Power Systems in True Wireless Stereo Devices

TDK Corporation has developed the PLEA67 Series of inductors for use in true wireless stereo (TWS) devices. TDK’s original structure design and newly developed materials in the new thin-film power inductors achieve a rated current of 500mA in a small-sized component with an inductance of 2.2μH. The unique magnetic shield structure reduces magnetic flux leakage, while the low-loss magnetic material provides a highly efficient power supply circuit, ideal for small power supply and low power consumption Bluetooth LE modules.
