VL53L1X Time-of-Flight (ToF) Long Distance Ranging Sensor
SKU: CQRWX00744US, ASIN: B07F3TV3G4
Description
The VL53L1X 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 VL53L1X 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.
The VL53L1X is a third-generation FlightSense technology time-of-flight sensor. Compared to the
second-generation VL53L0X, the VL53L1X extends the TOF ranging length to 4 meters and the
ranging frequency to 50 Hz. Unlike traditional ranging sensors, the VL53L1X uses ST's latest ToF
technology, which integrates physical infrared filters and optical components to provide distance
measurement and immunity to interference, regardless of target’s color and reflectivity.
