NSI has developed a 25mm industrial grade trackball. The unit is available with either a black phenolic ball (TBS25 series) or a stainless steel ball (SBS25 series). Both types feature a stainless steel carrier plate and a stainless steel top flange protecting the seal of the trackball and the two stainless-steel sealed switches. Compact dimensions of 82 x 67mm make these trackball units suitable for any application where minimal mounting space is required. Its vandal resistance and sealing to IP65 mean that they can be used in harsh industrial processes, kiosk consoles, navigation controls etc.
