VL53L4CX Time-of-Flight Sensor

Specifically designed for long-range, multitarget measurements, STMicroelectronics' VL53L4CX provides very accurate distance measurements up to 6 m with excellent results over short distances. A new generation laser emitter with 18° field of view (FoV) improves performances under ambient light.

Thanks to ST's patented algorithms and innovative module construction, the VL53L4CX is also able to detect multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 80 cm and dynamic smudge compensation for targets below 80 cm. Like all ToF sensors based on ST's FlightSense technology, the VL53L4CX records an absolute distance measurement regardless of the target color and reflectance. Housed in a miniature reflowable package, which integrates a single photon avalanche diode (SPAD) array, the VL53L4CX achieves excellent ranging performance even when hidden behind a wide range of cover glass materials.

All ST ToF sensors integrate a vertical cavity surface emitting laser (VCSEL), which emits a fully invisible 940 nm IR light that is completely safe for eyes (Class 1 certification).
