描述 Description

Specifically designed for proximity and short-range measurements, the VL53L4CD provides very accurate

distance measurements from only 1 mm up to 1300 mm. A new generation laser emitter with 18° FoV improves

performances 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 to reduce

design complexity as well as BOM cost since less powerful and less expensive microcontrollers can be used.

Like all Time-of-Flight (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, which integrates a SPAD (single photon avalanche diode) array, the

VL53L4CD achieves the best ranging 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 eyes (Class 1 certification).

Applications

? Proximity ranging applications such as:

– Wall tracking and cliff detection for robotics

– System activation and presence detection

– Touchless switch

? Very low power consumption for battery powered devices including:

– Access control

– Sanitary (faucets, dispensers, etc.)

– Home appliances (thermostats, lighting control, etc.)

? Fast ranging

– Bar code readers

– Biometric distance applications

– Virtual fences
