The X-Keys O-Trac from PI Engineering is a robustly built trackball with a long history of durability, reliability and performance, carrying on the legacy of the PC-Trac Trackballs formerly manufactured by Clearly Superior Technologies.

The X-Keys O-Trac Trackball offers a gently-angled profile that serves as a natural hand rest. The gradual curve of the body mirrors the natural contour of the hand and is designed to easily accommodate both right- and left-handed use, as well as multiple hand sizes.

Unlike most trackballs on the market, the high density phenolic trackball in the O-Trac has significant inertia. This provides far more tactile feedback than that normally offered by mass market trackballs, while still offering smooth response to even a light touch. The PC-Trac also offers "dynamic acceleration" which increases distance covered proportional to the speed of rotation. This feature ensures fine control as well as offering accurate rapid movement when required. (See the Features section on the Detailed Specifications Page for a deeper explanation of this feature.)

The O-Trac Trackball offers both "middle click" and "drag lock" functions (see the Features for more details

X-keys Trackballs work right out of the box, no software is required. If you wish to assign different functions to the buttons the manufacturer recommends using X-Mouse Button Control.

An X-Keys Programmable Foot Switch lets you use your foot to activate any keyboard command. The large center pedal has minimal travel for your most heavily used key action. The outer "piano-key" pedals offer two additional actions without having to search for a second and third footswitch on the floor!

Replace repetitive keystrokes or mouse clicks with the action of your foot. Enter, Tab, Shift, Ctrl, Alt... anything you can type on the keyboard can be memorized by the X-keys including Key combinations like Copy (Ctrl+C), Paste (Ctrl+V), Save (Ctrl+S), and Next Program (Alt+Tab). Left Click, Right Click, and Center Click easily program into the X-keys USB Foot Pedal (PS/2 Foot Pedal supports mouse clicks via Windows Accessibility Options).

Using the same proven hardware as the X-keys Programmable Keyboards, the X-keys Matrix Boards connect to the computer through a standard USB port. Your custom switches or keys connect to the board via a standard two row header with 0.1" pin spacing. Programming is done with a standard keyboard and memorized commands are fed to your computer as if they were coming from a standard keyboard. Any sequence or combination of keystrokes may be assigned to any of the 128 (USB) possible switches in the matrix. Any switch, even toggle and rotary switches, can be connected to the matrix.

Programming and reprogramming the switches is simple and fast. The X-keys stores scan codes in its internal memory -- it can be programmed on one computer and moved to another with its programming intact.

X-Keys Orby Switches from PI Engineering offer users a low (100 g) activation force with a clearly audible click for notification of both activation and deactivation. The 2.5" diameter surface activates the switch from any contact location and is large enough to provide a significant target zone without being two large for practical placement. The brightly coloured (Red, Yellow, Blue, and Green) buttons are highly visible and lend themselves to serve as visual cues to aid in identifying the command to be performed.Orby Switches connect to any control module or switch-adapted device that accepts the industry standard 3.5 mm plug. For stability Orby switches feature a non-slip backing or can be secured using the dual threaded brass inserts.

The X-Keys XK-12 plus Touchpad from PI Engineering is a 12 key programmable keypad with a touchpad having three modes or uses: as a pointer, a joystick, or a raw X-Y position control. Programmability includes macros, hot keys, or multiple steps or sequences. Other features include: red and blue backlighting for each key, and key caps and key blockers for creating custom layouts.

The X-keys Pendant Switch from PI Engineering is a rugged, commercial-duty switch primarily designed for light industrial or home workshop applications. This switch is useful in situations where a computer needs to be located a distance away from a working environment yet a few buttons are necessary to start or stop an operation safely with no exposure to potentially dangerous electrical currents.

When bundled with the X-keys USB HD15 Wire Interface and the standard HD15 extension cable, the Pendant Switch can send commands to any program controlled by a computer or tablet. Different models include 4, 6, or 8 buttons. Each button has a tactile feel, giving click feedback even through gloves. Each Pendant Switch also has an attachment pin for easy mounting.
