1. DESCRIPTION Utilizing the latest and most advanced infrared optical tracking technology, the X38 HALO Series optical Trackerball™ is an extremely high specification, contact-less device, ideal for use in low level light environments where accurate cursor control is critical. The trackball incorporates an illuminated ring around the ball to enable the user to locate the trackball in low light environments and offers an ideal solution for applications where a backlit ball would be too obtrusive. The HALO feature can also be used to compliment other backlit features within the user interface pane and is available in a wide range of colours. The optical tracking engine provides accurate cursor motion at all speeds and on virtually any ball, combining the benefits of solid-state sensing (no moving parts except the ball) with the aesthetics, functionality and performance associated with the Cursor Controls product range. The design incorporates a removable top ring as standard to allow for easy cleaning, decontamination, sterilisation and maintenance - ensuring continued optimum performance and operation under the harshest of conditions. The X38 HALO series trackballs are available with a variety of electrical outputs, tracking force options, and sealing capabilities up to IP68. The trackball has been designed to be back of panel mounted as part of OEM keyboards and consoles. 2.
