VL53L4CD Time-of-Flight High-Accuracy Proximity Sensor

Specifically designed for proximity and short-range measurements, STMicroelectronics' VL53L4CD provides very accurate distance measurements from only 1 mm up to 1200 mm. A new generation laser emitter with 18° FoV (field-of-view) improves performance under ambient light, with ranging speed up to 100 Hz.

With very low power consumption, thanks to an Autonomous mode with programmable distance threshold, the VL53L4CD is ideal for use in battery-powered devices. Its fully embedded on-chip processing helps reduce design complexity and BOM cost since less powerful and less expensive microcontrollers can be used. Like all ToF sensors based on ST's FlightSense technology, the VL53L4CD records an absolute distance measurement regardless of the target color and reflectance.

Housed in a miniature reflowable package that integrates a SPAD (single-photon avalanche diode) array, the VL53L4CD achieves excellent performance in various ambient lighting conditions and for a wide range of cover glass materials.

All of ST's ToF sensors integrate a VCSEL (vertical cavity surface emitting laser). It emits a fully invisible 940 nm IR light that is totally safe for the eyes (Class 1 certification).
