Panel mount miniature trackball
LT series
The LT series trackball utilizes advanced laser tracking technology in a sealed, contactless device that
provides precise and accurate cursor control at all speeds, with the versatility to fit most applications. The
design incorporates a standard removable bezel for easy cleaning, decontamination, sterilization, and
maintenance, ensuring optimum performance and operation under the harshest of conditions. The LT series
trackballs are available with a variety of electrical outputs, tracking force options, and sealing capabilities
up to IP68. Designed to be back-panel mounted in keyboards and consoles, LT series trackballs are often
used in medical systems, marine systems, custom keyboard applications, and industrial consoles.

ORIENTATION
The orientation function allows the user to mount the LT series trackball device in one of four positions as seen in the illustration
below. The orientation of the device is determined by the direction in which the output connector is facing (when viewed from the
top of trackball device). The trackball device orientation can be selected to accommodate customer requirements for connector
location and wiring.
