Trackball Mouse
KY-TB-25-3 Industrial Metal Trackball With Three Keys
KY-TB-25-3 is a sealed optical trackball mouse with a 25mm ball and three keys including right and left buttons on a SUS304 brushed stainless steel panel.
Product Overview
KY-TB-25-3 is a sealed optical trackball mouse with a 25mm ball and three keys including right and left buttons on a SUS304 brushed stainless steel panel. Panel installation and water proof sealing let it replace a mouse on machines that are washed down or left unattended. It suits control platform builders who need a middle button as well as the standard pair.
- Three keys give right left and an extra function button in one device
- 25mm ball keeps the panel cutout small
- Sealed water proof construction for washdown areas
- SUS304 brushed stainless steel panel and buttons resist riot damage and corrosion
- PS/2 and USB output for old and new hosts
- Working current under 150mA at 5V plus or minus 5 percent
Application Scenarios
- Industrial control platform desks
- Machine operator stations washed down after shifts
- Self service terminals needing a third button
- Laboratory and inspection consoles
- Panel installed HMI stations
- Equipment where a mouse cannot be used
Who It Is For
- Machine builders adding HMI pointing
- Industrial control panel integrators
- Self service terminal OEMs
- Laboratory equipment manufacturers
Problems It Solves
- Two button pointing devices lack a middle function key
- Water used for cleaning enters unsealed trackballs
- Mice cannot be fixed to a vertical control panel
- Corrosive plant atmospheres attack plated finishes
