Drop in panel-mount trackballs
Published: 12 July 2012 - Michelle Winny
A range of 38mm and 50mm rugged, panel-mount trackballs, 'powered by Pretorian' has been developed ITAC Systems.
They can be used with all common communications protocols including phase quadrature, USB, PS/2, Microsoft serial, Mouse Systems and Sun, reducing both inventory and minimising commissioning time.
The top plate of each trackball can be shimmed to customise the 'feel' of the ball for each application.
The trackballs come in IP65 sealed and unsealed versions. They have five-button and wheel inputs (supported in USB and PS/2 protocols), and feature optional backlighting and piezoelectric sounders for user feedback.
The devices are available in a variety of colours, with a choice of industry-standard connectors.
The Pretorian trackballs, which have been developed for reliable operation in demanding environments, guide fluids and other contaminants away from the printed circuit boards, the latter having filled vias for additional corrosion protection.
