AFBR-S50MV85I is a multi-pixel optical distance and motion measurement sensor module, based on the optical Time of Flight principle

AFBR-S50MV85I is a multi-pixel optical distance and motion measurement sensor module, based on the optical Time of Flight principle. The technology has been developed with a special focus on applications with the need for the highest speed and accuracy at medium distance ranges, with small size and very low power consumption. Due to its best-in-class ambient light suppression, use in outside environments is possible in full sunlight. The sensor accurately measures against white, black, colored as well as metallic and retroreflective surfaces.

Key features

  • Very Fast Measurement Rates: up to 3 kHz
  • Operation up to 200 kLux
  • Multipixel for 3D Motion Detection
  • Accuracy Error Typically Below ±1%

Additional features

  • An integrated calibrated clock source
  • Unambiguous range up to 100 m in 2f mode
  • Reference Pixel for system health monitoring
  • Laser Class 1 eye safety ready

Additional Info

The module has an integrated infrared laser light source and an internal clock source. A single power supply of 5.0 V is required. Data is transferred using a digital Serial Peripheral Interface (SPI) using standard 3.3 V CMOS levels. For system health monitoring a Reference Pixel is used in addition to the integrated voltage and temperature sensors. Frame rates of up to 3 kHz are supported, depending on the Microcontroller, the data streaming mode, and the number of evaluated pixels. For frame rates of up to 100 Hz, a dual-frequency (2f) mode is used to achieve an unambiguous range of 50 m in short-range and 100 m in long-range mode.
