シチズン電子 Company Profile

Citizen Electronics Co., Ltd. (Headquarters: Fujiyoshida City, Yamanashi Prefecture; President: Kanetaka Sekiguchi) has developed a "High-Power UVC LED Assembly Product for Sterilization" (hereinafter referred to as UVC LED Assembly Product) equipped with a high-output deep ultraviolet (UVC) LED that has a peak emission wavelength of 265nm, which is said to have high sterilization efficiency, and will begin mass production shipments in mid-April 2022. ■ Main Features 1. By adopting a high-reflectivity reflector, it enables uniform irradiation of the sterilization area for efficient sterilization. 2. Equipped with a high-output deep ultraviolet (UVC) LED at 265nm, which has high sterilization efficiency. 3. A high-output assembly product that allows for the replacement of sterilization lamps that have mercury content issues. 4. Dustproof and waterproof functionality (equivalent to IP54) allows for use in various environments. *Only for UVM001. This product has been jointly evaluated with Fujita Medical University (Department of Medicine, Virology and Parasitology, Associate Professor Kawamoto) for its inactivation effect on the novel coronavirus (SARS-CoV-2), confirming that it has high effectiveness as an assembly product rather than as a standalone UVC LED. (Details of the tests are published in our press release.) ◎ For more information, please visit our company website or contact us.

Citizen Electronics Co., Ltd. (Headquarters: Fujiyoshida City, Yamanashi Prefecture, President: Kanetaka Sekiguchi) has developed a surface mount tactile switch (a switch that provides a click feel when pressed) that achieves one of the world's smallest sizes for smartphones and wearable devices. Sample shipments will begin in late October, with mass production scheduled to start in April 2021. *As of October 2020, based on our research for top-press type tactile switches. ■ Main Features 1. Approximately 20% downsizing (volume ratio) compared to our conventional products, achieving one of the world's smallest sizes. Further miniaturization has been realized through improved processing precision of the components that make up the switch and enhanced assembly accuracy. New product LS165: Width 2.6 mm × Length 1.4 mm × Height 0.55 mm Conventional product LS160: Width 2.8 mm × Length 1.6 mm × Height 0.55 mm 2. High dust and water resistance By sealing the spring contact part, high dust and water resistance (equivalent to IP67) is ensured. 3. Structure resistant to lateral forces By integrating the actuator within the product, strength against external forces from the side is improved.
