The VL53L1X is a ToF sensor which embeds the ST’s third generation FlightSense patented technology. Compared with the second generation VL53L0X, the VL53L1X extends the ToF ranging distance up to 4m, and features fast ranging frequency up to 50 Hz.

Unlike conventional ranging sensors, the VL53L1X integrates physical infrared filters and optics, uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance, achieves better anti-interference capability.
