Description
•
•
Pin-to-pin compatible with the VL53L0X
FlightSense™ ranging sensor
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
Fast and accurate long distance ranging
–
–
Up to 400 cm distance measurement
Up to 50 Hz ranging frequency
•
•
Typical full field-of-view (FoV): 27 °
Programmable region-of-interest (ROI) size on
the receiving array, allowing the sensor FoV to be
reduced
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.
•
•
Programmable ROI position on the receiving
array, providing multizone operation control from
the host
Easy integration
Unlike conventional IR sensors, the VL53L1X uses
ST’s latest generation ToF technology which allows
absolute distance measurement whatever the target
color and reflectance.
–
–
Single reflowable component
Can be hidden behind many cover window
materials
–
Software driver and code examples for
turnkey ranging
It is also possible to program the size of the ROI on
the receiving array, allowing the sensor FoV to be
reduced.
