## Long description

The KeySonic ACK-540U+ is a mini wired office keyboard with an integrated Smart-Touchpad and UK English QWERTY layout. Finished in matte black SoftSkin coating, it includes blue status LEDs for Caps, Num and Scroll Lock and offers full-size layout functionality in a compact housing. The keyboard uses X-Type membrane technology to provide tactile feedback with an extremely quiet keystroke and connects reliably via a 1.9 m USB 2.0 cable.
Advantages
The compact design saves desk space by integrating a numeric keypad into the letter keys, activated via a function key. The built-in Smart-Touchpad with two mouse buttons removes the need for a separate mouse. The SoftSkin surface and rounded design improve typing comfort, while the X-Type membrane ensures quiet operation and clear tactile response. Wired USB connection provides stable and consistent communication with desktop or notebook computers.
Suitable for
Office tasks and data entry in limited workspace
Notebooks or desktop setups where an external mouse should be avoided
Shared workstations where quiet typing is preferred
