Should I assume that detection is not possible in direct light?
- ANSWER
- The maximum ambient operating illumination of the sensor is 30,000 Lx.
Even in bright sunlight, and even if light shines directly on the sensor or on the object of detection, the sensor will operate correctly as long as the illumination does not exceed 30,000 Lx.
However, if an inverter light is directly within the detection area of the sensor (plus or minus several degrees), the sensor will not operate correctly.
This is because the sensor cannot distinguish between light emitted from the sensor and light from the inverter light.
The sensor will operate correctly in the direction of the sun as long as its optical axis does not point directly toward the sun. The field of detection of the sensor is plus or minus several degrees, so there will be no problem if the sensor’s optical axis is shifted 15°away from the sun.
