The Smartest Arcade Trackball Ever!
Now with improved translucent ball! 80% more light transmission!

We started from the ground up rather than take an existing unsuitable unit and try to modify using add-on parts. This way we were able to address all of the problems with current designs, namely the difficulty of fitting to a wood panel, plus the poor "out of the box" spin of many trackballs. 

In addition we were able to use the best quality translucent balls available. The red version is so attractive even when not lit that we decided not to bother with a solid red option. The pearl ball can be used to produce stunning multi-color lighting effects. 

USB2 interface, USB Cable and Mounting hardware are included, with special high-strength expanding screw sleeves which enable easy fitting with no screws visible from the top. 
(If you don't need all the buttons or the joysticks provided by an I-PAC, you can use the USB2 interface to connect the U-Trak trackball directly to your computer!)

Can be mounted with or without bezel.
Panel thickness up to 3/4 inch (19mm).

Full-Speed USB interface
3In Diameter ball.
RGB LED lighting PCB available.
USB Interface supports left/right mouse buttons. 

Mounting Methods:
4 Screws and expanding brass inserts are supplied. The inserts are designed to fit into blind holes and nothing shows from the top of the panel.

Important note:
Check carefully that the supplied screws will not pierce through the top of the panel by checking the length before fitting. 

Mounting without trim bezel:
Using a hole saw or fly-cutter, drill a hole 3 1/4 inch diameter (82mm). Note the vertical part of the housing is slightly conical to enable it to be molded in one piece, so to enable a perfect fit you will need to enlarge the hole from the underside of the panel slightly, using a file.

Fit the trackball with the arrow on the top of the housing pointing to the rear of the panel. Drill 4 "blind" pilot holes through the mounting holes. Then remove trackball and enlarge holes to 1/4 in (6mm). TIP: To drill blind holes use tape wrapped around drill as a depth guide. Tap the expanding inserts into place. Install trackball and screw into place. 

Mounting with trim bezel:
The optimum panel thickness for this method is 5/8 in (17mm). A 3/4 inch panel can be used but the flange will sit 1/8 inch above the ball surround. Using a fly-cutter or hole saw cut a hole approx 3 3/8 inch (86mm) diameter. You may find a 3 1/2 inch or 90mm hole saw is easier to find and this will work fine. 

Fit the trackball with the arrow on the top of the housing pointing to the rear of the panel. Drill 4 "blind" pilot holes through the mounting holes. Then remove trackball and enlarge holes to 1/4 in (6mm). Tap the expanding inserts into place. Install trackball and screw into place. Push the bezel over the housing. Glue can be used if required 

Connections (Non-USB)

Connections (USB)
The USB interface supports left and right mouse buttons. Suitable wires with contacts are contained in the "Mini-PAC Extension harness Pack" which can be ordered in the Mini-PAC section of our store.
The black wire shown arrowed in the above picture is not used by the trackball. This is the left button connection.
The unused contact next to this is the right button connection.
The COM terminals of the mouse button switches should be connected to a convenient ground point (Eg an I-PAC ground, or PC casing).
