ST Announces 4m Range ToF Sensor

The VL53L1X TOF sensor extends the detection range of ST's FlightSense technology to four meters, bringing high-accuracy, low-power distance measurement, and proximity detection to an even wider variety of applications. The fully integrated VL53L1X measures only 4.9mm x 2.5mm x 1.56mm, allowing use even where space is very limited. It is also pin-compatible with its predecessor, the VL53L0X, allowing easy upgrading of existing products. The compact package contains the laser driver and emitter as well as SPAD array light receiver that gives ST’s FlightSense sensors their ranging speed and reliability. Furthermore, the 940nm emitter, operating in the non-visible spectrum, eliminates distracting light emission and can be hidden behind a protective window without impairing measurement performance.

ST publishes quite a detailed datasheet with the performance data:
