The long-awaited new series of "Keiko-chan"! Compact and low-priced! The palm-sized USB-compatible warning light "Doko Demo Keiko-chan" is now on sale.

ISAI Corporation has developed a compact palm-sized warning light called "Doko Demo Keiko-chan," which is designed to adapt to changes in lifestyle such as "recent work styles" and "new living standards," while also considering various environments and usage scenarios. The first two models, compatible with USB (DN-1600U/UD), will go on sale starting October 29.
Until now, USB-compatible warning lights have primarily been used in business settings, but recently, there has been an increase in opportunities to install them in places where the general public can see them, such as in medical and educational settings. Therefore, ISAI has developed a compact palm-sized warning light within the Keiko-chan series that is most adaptable to the environment and can be easily installed anywhere, including on walls and ceilings.
In addition to a complete redesign of its appearance and size, new features have been added, such as a non-contact sensor for deactivating the alarm, taking into account hygiene considerations in light of recent infectious disease measures. The lamp offers a wider selection of color differentiation with seven multi-colors: red, yellow, green, blue, aqua, purple, and white.
