VAD coverage (with multiplication factors applied)

VAD coverage depends on factors such as ambient light and viewing angle (direct or indirect). The table below summarises how the coverage of the BF433A/CX/DR increases or decreases based on these factors. To use the table, calculate the lux level of the area requiring coverage, determine whether the viewing angle will be direct or indirect then read off the coverage in the relevant column. For further information refer to our VAD System Design Guide, downloadable from the Documentation tab below.
