VL53L1CX in ST VL53Lx Time-of-Flight Family
The VL53L1CX is a high-performance Long Distance Ranging sensor within the FlightSense product line from STMicroelectronics. This Time-of-Flight (ToF) device integrates a SPAD array, physical infrared filters, and specialized optics to measure absolute distances regardless of target reflectance. It is primarily used in applications requiring accurate distance sensing up to 4 meters, offering improved immunity to ambient light and better ranging performance compared to previous generations by utilizing a 940nm invisible laser source.
Variants in This Sub-Family
The VL53L1CX family primarily varies in terms of optical packaging and specific firmware configurations. While the base silicon provides the same SPAD-based time-of-flight engine, different variants may offer optimized cover glass calibrations or specific API support for specialized ranging modes. Engineers should distinguish between the standard CX variant and L1X versions, which may differ in maximum ranging distance and field-of-view characteristics.
