Elecom Numeric Keypad Bluetooth Quiet Design Antibacterial Windows/Chrome OS/macOS Compatible Black TK-TBM023SKBK

This is a Bluetooth(R) silent numeric keypad that is ideal for use in places and times when noise is a concern.The silicone rubber attached to each key top reduces keystroke noise by more than 90 compared to conventional products. It is ideal for use in public facilities, conference rooms, in places where noise is a concern, such as in the middle of the night or early in the morning. 11 This is the result of comparing the magnitude of the sound energy calculated from the sound pressure level of the keystroke sound of this product (approximately 15dB) and the conventional model TK-FCM062BK (approximately 45dB). Sound energy is a value calculated from the measured sound pressure level (bell value) and a reference value (minimum volume of sound that humans can hear).By installing its own firmware, it can be used on Windows, Chrome OS, and macOS.Even if liquid such as water is accidentally spilled on the keyboard, it is equipped with a drainage mechanism that can immediately drain the liquid from the drain hole on the back of the main unit.
