The Broadcom AFBR-S50LX85D is a state-of-the-art multi-pixel optical sensor module designed for precise distance and motion measurement using the Time-of-Flight (ToF) principle. This innovative technology is tailored for applications that demand exceptional speed and accuracy over extended distances, while maintaining a compact form factor and minimal power consumption. Its advanced design allows for reliable performance in outdoor environments, even under full sunlight, thanks to its effective ambient light suppression capabilities. The sensor's versatility is highlighted by its ability to deliver accurate measurements across a variety of surfaces, including white, black, colored, metallic, and retroreflective materials.

At the core of the AFBR-S50LX85D is an integrated infrared laser light source, coupled with an internal clock, which operates on a single 5.0V power supply. The module communicates data through a digital Serial Peripheral Interface (SPI), utilizing standard 3.3V CMOS levels. This efficient design includes a reference pixel for system health monitoring, alongside integrated voltage and temperature sensors for enhanced reliability. The sensor supports frame rates of up to 3 kHz, contingent on the microcontroller, data streaming mode, and the number of evaluated pixels. For applications requiring frame rates up to 100 Hz, the sensor employs a dual-frequency (2f) mode, enabling an unambiguous range of up to 200 meters.

The AFBR-S50LX85D also boasts a compact size, with dimensions of 12.4 mm × 7.6 mm × 7.9 mm, making it an ideal choice for space-constrained applications. It features a receiver with 32 pixels, each with a field of view of 1.55° × 1.55°, and a transmitter beam width of 2° × 2°, typically illuminating 1 to 3 pixels. With a distance range extending beyond 50 meters and an operational temperature range of –20°C to 70°C, this sensor module is engineered for robust performance across diverse conditions. The SPI digital interface supports data transfer rates up to 25 MHz, ensuring swift and efficient communication for a wide array of applications.
