With this external numeric keypad, you can alternate between your left and right hand, and you can flexibly put it away, when you don’t need the numeric. For efficient and comfortable typing the S-board 840 Numeric has a scissor mechanism for its keys, a key centre distance of 19 mm, anti-reflective white keys with dark lettering, and a concave key shape.
This external numeric keypad has a calculator function with eight useful extra keys, convenient integrated navigation keys and two LED displays for showing on and off and for NumLock. With the S-Board 840 Numeric you can not only enter productively large data quantities, but you can also use the great calculator mode to be more efficient at work and increase your personal performance.
Position it on either side of your keyboard, opposite your mouse, or move it aside entirely when not needed. This keeps your mouse within closer reach, helping reduce shoulder tension and promoting a more natural, relaxed posture throughout the day. This being the key ergonomic factor of using a separate numpad.

Why Choose a Separate Numpad?
-
Less reach, less strain: Your mouse stays within easy reach.
-
Use either hand: Swap sides to balance out muscle use.
-
Slide it away when not needed: Maximise desk space for other tasks.
-
Compact setup: Perfect for modern, minimalist workstations.
