TDK Corporation (TSE:6762) announces the HVC50, a high-voltage DC contactor designed for connecting or disconnecting lithium-ion batteries with up to 1500 V in traction applications, energy storage systems (ESS), and megawatt charging systems (MCS). With this component, TDK enables its customers to drive the green transformation towards an all-electric society and reduce carbon footprint.

TDK Corporation (TSE:6762) announces two new additions to its high-voltage contactor portfolio for harsh environments: the HVC43MC with integrated mirror contact and the HVC45 with enhanced short-circuit current handling capability. These new contactors for up to 1000 V (DC) enable reliable switching of lithium-ion batteries in traction applications, energy storage systems (ESS), and DC charging stations. These components underscore TDK’s dedication to enabling the transition to a greener, more electrified future.

With an integrated mirror contact according to IEC 60947-4-1, the HVC43MC enables safe detection of the main contact's position. This mechanically linked auxiliary contact provides reliable feedback about whether the main contact has opened or closed, enhancing system safety monitoring. The contactor can handle continuous currents up to 250 A and cut-off currents up to 450 A at 1000 V (DC) and 2000 A at 450 V (DC), respectively, all in a compact package measuring 74.5 x 78 x 40.5 mm.

With a short-circuit current handling capability of up to 12 kA for 5 ms, the HVC45 sets an industry benchmark, surpassing conventional solutions in its size class that typically achieve 8 to 10 kA. This enhanced capability addresses the requirements of modern high-energy-density batteries that can achieve higher short-circuit currents. The contactor can handle continuous currents up to 300 A and features a maximum cut-off rating of 900 A at 1000 V (DC) and 2200 A at 450 V (DC), respectively.

Both series incorporate TDK's proven gas-filled ceramic arc chamber technology and bidirectional switching capability, allowing current flow in both directions. The contactors are available with 12-V or 24-V coil voltages and are certified to CE, UKCA, and UL standards, supporting worldwide deployment.

In applications like process automation and food and beverage production, data often needs to be transmitted from sensors within closed metallic structures. So, how to get data into and out of these without drilling a hole? Acoustic Data Link is TDK’s answer.

Augmented and Virtual Reality (AR/VR) is one of the next big things. It creates entirely new experiences for consumers and commercial users. However, many of these devices focus solely on the visual dimension. With tactile feedback, AR/VR becomes more immersive by addressing other sensory experiences. TDK's multilayer piezo ceramic PowerHap actuators can render surface textures crisply, as demonstrated impressively by WEART's TouchDIVER.

TDK Corporation (TSE:6762) presents a development starter kit for fast haptics prototyping. It gives mechanical designers and engineers first impressions of the haptic feedback with PowerHap piezo actuators, shows how the mechanical integration works, and provides a reference design, which can be adapted to various applications. PowerHap piezo actuators offer an unprecedented quality of haptic feedback based on their unrivaled performance of acceleration, force, and response time. Example applications include automotive (e.g., steering wheels, displays, dashboards, buttons), smartphones, displays and tablets, household appliances, ATMs and vending machines, game controllers, VR gloves, industrial equipment, and medical devices.

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.
