Lightcurtains

Lightcurtains
Different to traditional light curtains, the CRB does not check only the 1 to 1 beams; it checks also the
crossed beams to detect an object. This method combines an extrem/y high resolution with a good
resistance in dirty environments. Due to the operating principle its resolution depends on the object
to be detected. The wider it is, the thinner it can be; e. g. a sheet of paper The output becomes
active if at least one beam between the transmitter and the receiver has been interrupted. A cable
connection between both devices is not needed - the system synchronizes by infrared. lf the light-
curtain has to be used at low operating distances, its transmitt power can be reduced by connecting
a potentiometer .
