X-keys L-Trac Black Trackball
The X-Keys L-Trac Black Trackball from PI Engineering combines a high level optical sensor capable of resolutions up to 1600 CPI (counts per inch) with a robust build and history of durability, reliability and performance, carrying on the legacy of the L-Trac and PC-Trac Trackballs formerly manufactured by Clearly Superior Technologies. The L-Trac features an optical laser sensor that offers "button selectable" tracking resolutions of 400, 800 and 1600 CPI, easily changed on the fly. Combined with this is the ability of the L-Trac to track at speeds exceeding 30 inches per second, even at a 20G acceleration rate. A wide light touch scroll wheel or cylinder is readily accessible, located above the center button. In addition, two 3.5 mm jacks permit the attachment of two external switches which can be programmed to perform an additional two actions, resulting in full 5-button functionality.
The L-Trac provides users with a precision, high performance pointing device. The large 57 mm diameter weighted trackball produces predictable, quick, and precise cursor control. Most users will find that movement becomes intuitive within a few minutes of use, with the level of control increasing over time.
The level of performance and range of features, coupled with the proven contour of the L-Trac makes these trackballs an appropriate option for all applications including general computing, gaming and Computer Aided Design (CAD). CAD users love it because a line can be dragged one pixel even on high resolution displays. Then, with a button stroke, the cursor can fly around the screen to get general tasks done. The L-Trac is known for providing fingertip control and precision, high performance tracking.
Designed to minimize the effects of contamination build up and the resultant degradation of performance, this high performance laser trackball uses highly polished stainless steel rollers. These rollers tend to collect less dirt and debris than the mechanisms used in most other trackballs and are easily cleaned by spinning the ball rapidly.
