Time-of-Flight (ToF) ranging sensors can measure distance accurately using laser light and are sold in a really tiny package. STMicro VL53L0X ToF sensor may be the most popular with a 2 meter range, and its ultra low cost.
The sensor got an extended range up to 4 meter with the recent launch of VL53L1X, but STMicro is not the only company providing such solution, and Broadcom has just introduced their AFBR-S50 ToF sensors for industrial applications and a range of up to 10 meters.
Two versions are offered with different laser light sources, field of view, and number of pixels:
- AFBR-S50MV680B
- 680nm laser light source
- One illuminated pixel
- FOV 1.55° x 1.55°
- Single voltage – 5V supply
- AFBR-S50MV85G
- 850nm laser light source
- 9-16 illuminated pixels
- FOV 6.2° x 6.2°
- Single voltage – 5V supply
The multipixel version of AFBR-S50 supports up to 3,000 frames per second with up to 16 illuminated pixels out of 32, and is operational under ambient light conditions up to 200k Lux. A SPI interface is used to communicate with the host.
The solutions is suitable for industrial sensors, gesture sensing, distance measurement, robotics, and automation and control.
