R55 Series
The R55 Series is a professional desktop trackball designed for precise cursor control over prolonged periods of use. Constructed from high impact plastic, and featuring robust mechanics, it is ideally suited for use where reliability and extensive life span are prerequisites. The module is supplied with three integrated switches which provide the conventional left, middle and right button functionality found in commercial trackballs/mice. It can be directly connected to any personal computer via the USB or PS/2 port.
