AFBR-S50MV85I Datasheet | Broadcom

Description The Broad® 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 highest speed and accuracy at medium distance ranges, with small size and very low power consumption. Due to its ambient light suppression, use in outside environments is possible in sunlight. The sensor accurately measures against white, black, and colored surfaces as well as metallic and retroreflective surfaces. The module has an integrated infrared laser light source and an internal clock source. A single power supply of 5.0V is required. Data is transferred using a digital Serial Peripheral Interface (SPI) using standard 3.3V 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 k Hz 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 up to 100m.
