APPLICATION ENGINEERING
Trackball Applications
Application imagery is illustrative. SDBALLS supplies the trackball sphere, not the complete mouse, control panel or medical equipment.
Computer Peripherals
Precision trackball spheres for mouse and specialized pointing-device applications.
Industrial Controls & HMI
Trackball spheres for operator interfaces, industrial control systems and specialized equipment.
Medical Equipment
Trackball spheres for medical equipment interfaces requiring controlled movement and reliable user interaction.
Custom OEM Equipment
Specialized spheres for equipment requiring custom size, color, pattern or surface characteristics.
SYSTEM COMPATIBILITY
Optical & Mechanical Trackball Applications
Optical Trackballs
Optical trackball systems detect sphere movement through optical sensing. Surface appearance, pattern, dimensional consistency and compatibility with the customer's sensor system should therefore be confirmed during product development.
Mechanical Trackballs
Mechanical trackball systems rely on physical movement transfer within the pointing mechanism. Diameter, roundness, surface condition and smooth movement are important selection factors.
Final compatibility should be validated in the customer's actual trackball assembly or sensor system before mass production.
