A new optical track ball module for use alongside a keyboard or touch screen has been launched by EAO, the expert for Human Machine Interfaces. The optical track ball module is ideal for use in information and communication terminals for the public, such as those in libraries or art galleries, however the stainless steel construction and high protection up to IP68 against water and dirt ingress makes it equally suitable for use outside or in dirty environments like factories.
This optical track ball module is maintenance free and has no moving parts; vandal-resistant to IK09 with internal shock absorbers; resistant to light diffraction whatever the liquid due to EAO’s patented system.
The optical track ball mouse module is available with either one or two click buttons and connects through either a USB or PS2 interface. The actual track ball itself is available with either a 38mm or 50mm diameter.
EAO also offers a non-optical version of the track ball module in plastic or stainless steel, which is sealed to IP65. The track ball mouse module an be supplied on its own or with the EAO W.series rugged metal keyboard.
