VL53L1X in ST VL53Lx Time-of-Flight Family
The VL53L1X is a state-of-the-art, long-distance Time-of-Flight (ToF) ranging sensor from STMicroelectronics, extending the FlightSense product family. Unlike conventional IR sensors, it utilizes an invisible 940nm Class 1 laser emitter combined with a SPAD photon detector to measure absolute distance regardless of target color or reflectance. It offers accurate ranging up to 4 meters, making it a critical component for proximity sensing and presence detection in diverse industrial and consumer electronic systems.
Variants in This Sub-Family
Variants within the VL53L1X sub-family primarily differ by their packaging and integration level. The base silicon is offered in a compact LGA12 package, while evaluation variants like the VL53L1X-SATEL provide breakout boards for rapid prototyping. Some specialized versions may include pre-installed protective glass or unique calibration parameters for specific optical housings, though the core SPAD array and I2C command set remain consistent across the sub-family.
