General Description
The PMT9123QS-TVIT is PixArt Imagings low power, right angle Optical Track Sensor in a small form factor QFN package. It has a new low-power architecture and automatic power management modes, based on optical navigation technology that enables digital surface tracking, ideal for battery-powered wireless input devices. The PMT9123QS-TVIT integrates optical sensor and IR LED light source in a single SMT package, and together with LST0-M30 lens assembly, form a complete and compact tracking system that does not require code wheel, code strip and any special marking on tracking surfaces for motion control or tracking purposes.
