How It Compares
| Optical touchpad | The 50mm mechanical ball responds to gloved and wet hands that defeat optical sensing |
|---|---|
| Plastic trackball unit | A stainless steel ball in a SUS304 housing withstands vandalism and corrosion |
| External USB mouse | Nothing is removable, so unattended machines keep their pointing device |
Use Guide
- Provide a 50mm ball clearance in the panel cutout
- Mount so the ball sits proud enough to be spun with a gloved hand
- Wipe around the bezel regularly to stop grit reaching the rollers
- Avoid abrasive pads that would mark the stainless housing
