The change in the physical quantity detected causes a continual change in the
Changeover function (anti-valent switching function)
An output with N/O function and an output with N/C function are available
The output is switched through if the photoreceiver is unilluminated.
A digital output occurs if a change of a detected physical quantity results in a step
response of the output signal.
The output is switched through if the photoreceiver is illuminated.
Normally closed function (N/C)
The output is open if an object is detected and switched through if an object is not
Normally open function (N/O)
The output is switched through if an object is detected and open if an object is not
Delay time between the actuating element leaving the active zone and the signal
change at the output. The minimum required distance between two elements is
determined by this time taking into account the travel time.
