The GK38 series are ruggedised professional trackballs for harsh
industrial environments. The double-sided seal ring provides a
sealing to IP65 static (ball in rest). Stainless steel shafts and bearings
ensure a solid and precise pointer control. The unit can be used for
frontpanel mounting (remove the mounting bracket) or for
Optional Anti-Vandal Backplate
This additional backplate and mounting spacers enable the unit to absorb a very high level of abuse or impacts. When mounted properly by the end-user, this backplate will limit the hostile impacts on the ball to an acceptable level and protect shafts, bearings and other components of the unit.
