TDK Corporation (TSE: 6762) has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V coils with a power consumption of 6 W.

PiezoListen is the world's first piezoelectric type speaker that supports a wide range. Thanks to a world leading thinness of 0.49 mm, it can fit almost anywhere. The product causes the object to which it is glued to vibrate and thereby become a speaker. Because the entire surface vibrates, the sound has wide directivity, and uniform sound can be enjoyed at any location. You can also listen to music from Piezo Listen ™ piezo speakers.

Haptic devices are starting to be used for applications such as industrial or automotive monitors, displays on white goods such as washing machines, etc. However, these devices are also suitable for smartphones, notebook computers, and other ICT products.
TDK offers haptic device products utilizing the piezoelectric effect.

The methods of use of automobiles will change substantially in the future including autonomous driving and car sharing services, and the human machine interface (HMI) between drivers and their cars will also completely change.
The automobile industry is developing the digital cockpit in pursuit of an HMI that will provide safety and reassurance while freeing drivers from the burdens of driving and allow time to be used meaningfully and in comfort.
Below is an introduction to TDK product and technologies that enhance the value of the digital cockpit with the aim of achieving an HMI that ensures and enhance safety and reassurance through the driver's senses.

Whether for smartphones, vehicles, industrial controls, home appliances or gaming consoles – the future belongs to piezo-based solutions with haptic feedback. TDK offers a unique portfolio of products that are suitable for every imaginable haptic application.

TDK’s High-Voltage Contactor (HVC) Series is designed to meet the demands of high-voltage and high-current DC applications, especially for the disconnection for high-voltage lithium ion batteries. The hermetically sealed and gas-filled design is based on more than 80 years of experience with gas tube technology. The HVC series can be used in a wide range of applications where fast and reliable disconnection of high DC voltages is required.

Surface treatment is indispensable for the secure bonding of plastic parts. Activation with cold plasma is an equally simple yet elegant solution. Relyon Plasma, a subsidiary of TDK Electronics, offers the piezobrush® PZ2 – a handy plasma source based on the TDK CeraPlas™ piezo plasma generator.

TDK Corporation presents two evaluation kits that provide an initial impression of the varied possibilities of haptic feedback that can be realized with PowerHap™ piezo actuators.

TDK Corporation has extended its portfolio of PowerHap™ piezo actuators for haptic feedback with the new miniature rectangular 0904H014V060 and 1204H018V060 actuators. They have dimensions of only 9 x 3.75 x 1.4 mm and 12 x 4 x 1.8 mm, respectively.
