R38-15637F Ergonomic Desktop Trackball Module, USB R38 Series (Cursor Controls)

The R38 Series desktop trackball module is an ambidextrous, high specification device that incorporates the
latest Cursor Controls Ltd capacitive/touch technology.

The module combines the patented optical trackball technology with a capacitive, Z-axis scrolling ring allowing
vertical and horizontal scrolling.

To compliment these two technologies, the module also includes left, middle, right, forward, and backward
buttons and a resolution button allowing the user to select from five resolution configurations. The user can also
switch easily between left and right-hand configurations via a designated button.

The solid-state design prevents entry of dust and dirt, allowing easy cleaning of the trackball area once the ball
is removed.

The unit has been designed to be a freestanding desktop device and optimises desk space when compared to a
mouse.
