3-1-3 Auxiliary Output Switching Function
This function changes the operation state of the auxiliary output. It is useful when desired to make an
indicator to operate or inform the operation state of the
SF4B
/
SF4B<V2>
series to PLC.
The following settings are selectable.

when an obstacle exists in the sensing range regardless of the incident light intensity.
Do not use the auxiliary output for the purpose of stopping the machine in which the
SF4B

SF4B<V2> series
is installed. Failure to do so could result in death or serious injury.
