STMicroelectronics VL53L3CX

The VL53L3CX is the latest Time-of-Flight (ToF) product from STMicroelectronics and embeds ST’s third generation FlightSense patented technology. It combines a high performance proximity and ranging sensor, with multi target distance measurements and automatic smudge correction. The miniature reflowable package integrates a single photon avalanche diode (SPAD) array and physical infrared filters to achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover glass windows. It combines the benefits of a high-performance proximity sensor, with excellent short distance linearity up to 5 m.
