The embedded industrial trackball is a robust pointing device designed for precise 2D X-Y coordinate control in demanding operating conditions. Its stationary footprint is ideal for space-constrained operator consoles where traditional mice cannot be used, such as medical ultrasound workstations and naval navigation terminals.
