ELECOM Wireless with Numeric Compact Compatible with Windows Black TK-QT30DMBK Keyboard, Quiet, Keypad, Thin, Size, ChromeOS, macOS,

This is a low-profile, wireless keyboard with a truly silent design that provides a light typing experience. The compact size allows you to effectively use the space around your desk, and it comes with a numeric keypad that is convenient for entering numbers. Silicone rubber attached to each key top reduces keystroke noise by more than 90% compared to conventional products. Ideal for use in public facilities, conference rooms, and other locations and times when noise is a concern, such as late at night or early in the morning. *This is the result of comparing the size of sound energy calculated from the sound pressure level of the keystroke sound of this product (approximately 15 dB) and the conventional model TK-FCM062BK (approximately 45 dB). Sound energy is a value calculated from the measured sound pressure level (Bell value) and the reference value (the minimum loudness of sound that humans can hear). By installing its own firmware, it can be used with Windows, ChromeOS, and macOS. Adopts a thin key with a key stroke of 1.4mm, allowing for quick key input. Despite its compact size, it has a key pitch of approximately 19 mm and an isolation design that makes it easy to type, and the use of a large enter key and independent placement of Print Screen/Insert/Delete allows for comfortable typing that prevents incorrect input.
