Abstract
Provided is a multi-axis photoelectric sensor that outputs a high-level signal while a detection area is not shielded and stops the signal output when the detection area is shielded, wherein a sequence of a change in a non-shielded state and in a shielded state of the detection area formed by optical axes and inputs from muting sensors are divided into a plurality of stages for monitoring, and muting processing is executed when the stages progress normally. When an abnormality in the sequence is detected in a stage being monitored, indicator lights are blinked by a number of times corresponding to the stage in which the abnormality has been detected, to provide a notification of a stage in which the abnormality has been detected.
