SANWA SUPPLY SKB-TR03BK Trackball Keyboard Trackball Keyboard for Users

This compact keyboard features an integrated optical trackball, eliminating the need for a separate mouse. With no numeric keypad, it is designed for efficient use in tight spaces. The trackball function allows you to control the cursor with your fingertips, minimizing hand movements.

The keyboard connects via a USB interface, enabling both the keyboard and trackball to be used together. Its thin membrane system and rubber dome key top support provide a light, yet secure, typing experience with thinner and shorter key strokes compared to traditional keyboards.

Specifically, the keyboard has an 89-key Japanese 109A layout. The key switch mechanism is membrane-based, with a key pitch of 0.7 inches (19 mm), except for the letter keys. The keystroke depth is 0.1 ± 0.008 inch (3.0 ± 0.2 mm), and the operating force is 1.8 ± 0.3 oz (50 ± 8 gf).

The compact dimensions of this keyboard measure 12.0 inches (303 mm) wide, 6.3 inches (159 mm) deep, and 1.2 inches (30 mm) high. It features two buttons for the integrated trackball, which has an optical sensor with a resolution of 1,000 DPI.

This model is compatible with Windows 10, 8.1, 8, and 7 operating systems. It is designed for use with DOS/V PCs and is guaranteed to work with the USB port provided by the computer manufacturer.

The integrated keyboard and trackball design, along with the thin membrane system and compact form factor, make this a versatile input device for efficient computer use in limited workspace environments. The combination of keyboard and cursor control functionality in a single unit provides a streamlined and convenient solution.
