Description
AI
The VL53L4ED is specifically designed for high-accuracy, short-range measurements requiring extended temperature capability. It offers an 18° field of view for measurements from 1 mm up to 1300 mm in standard conditions, and up to 1150 mm under its extended temperature. Special settings also provide an accurate distance measurement up to 800 mm under ambient light conditions (5 klx).
This sensor has an effective temperature range of -40°C to 105°C, ensuring reliable measurement, even in extreme temperature conditions. It is the ideal product for industrial devices requiring proximity sensing. Examples include presence detection and system activation applications. The VL53L4ED is a direct derivative of the VL53L4CD with which it is pin-to-pin compatible. Its fully embedded on-chip processing helps to reduce design complexity and BOM cost because less powerful and less expensive microcontrollers can be used.
Like all Time-of-Flight (ToF) sensors based on STMicroelectronics' FlightSense technology, the VL53L4ED records an absolute distance measurement regardless of the target color and reflectance.
The VL53L4ED is housed in a miniature reflowable package. It integrates a SPAD (single photon avalanche diode) array, and consequently achieves the best ranging performance in various ambient lighting conditions, for a wide range of cover glass materials.
This sensor integrates 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).
