STMicroelectronics VL53L1CXV0FY/1 – Long distance ranging Time-of-Flight sensor based on ST’s FlightSense™ technology
The VL53L1CXV0FY/1 is a state-of-the-art, Time-of-Flight (ToF), laser-ranging sensor, enhancing the ST FlightSense™ product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz.
Housed in a miniature and reflowable package, it integrates a SPAD receiving array, a 940 nm invisible Class1 laser emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options.
Unlike conventional IR sensors, the VL53L1CXV0FY/1 uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance.
It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
