The Dell Pro Wireless Keyboard and Mouse KM526 in a sleek Black finish is a coordinated peripheral set designed to streamline your workspace using a single USB Type-A receiver. The keyboard features plunger switch technology and a spill-resistant, abrasion-proof surface that helps it withstand the rigors of daily office use, while an adjustable tilt allows you to find a comfortable typing angle. To help you work more efficiently, it includes 16 programmable keys alongside dedicated hotkeys for functions like the calculator and print commands. Complementing the keyboard is a symmetrical, full-size optical mouse in matching Black with three programmable buttons and a resolution that can be adjusted from 1600 up to 6000 DPI for precise cursor control. Both devices are built for longevity, utilizing batteries that can last up to four years, and are constructed from up to 77% post-consumer recycled plastic. This set is compatible with a wide range of systems, including Windows, macOS, ChromeOS, and various Linux distributions, and can be further customized through the Dell Display and Peripheral Manager software.
