Broadcom AFBR-S50MV85I Time-of-Flight Sensor Module

Broadcom AFBR-S50MV85I Time-of-Flight (ToF) Sensor Module is a multi-pixel optical distance and motion measurement sensor. The AFBR-S50MV85I is optimized for industrial sensing applications for short to medium distances of typical up to 5m. The module has an integrated 850nm laser light source, and due to a 13° x 6° emission cone, it can use all 32 Pixels simultaneously, independent of the object distance. Due to its ambient light suppression, use in outside environments is possible. The AFBR-S50MV85I Sensor accurately measures against white, black, and colored surfaces, as well as metallic and retroreflective surfaces.

The AFBR-S50MV85I 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 3kHz are supported, depending on the microcontroller, the data streaming mode, and the number of evaluated pixels. For frame rates of up to 100Hz, a dual-frequency (2f) mode is used to achieve an unambiguous range of up to 100m.

The Broadcom AFBR-S50MV85I ToF Sensor Module is provided in a compact 12.4mm x 7.6mm x 7.9mm package, with a -20°C to +70°C operating temperature range.
