6.3 External illumination
An external illumination can be connected to facilitate object recognition.
Connect the external illumination to switching output OUT1 of the unit. The sensor triggers the
illumination independently or passes the trigger signal through to the external illumination unit.
Since the sensors with infrared light have a band-pass filter, only external illuminations with a wave
length range between 780 nm...880 nm can be used.
Example: illumination unit O2D9xx.
The internal and external lighting is switched on 500 µs before the image is taken. Switching on
prematurely does not affect the brightness of the captured image.
w
Example: With an integration time of 100 µs, the lighting is switched on for 600 µs.
