Abstract
A photoelectric switch reduces a cost load of a user while ensuring its protection function inherent to safety equipment without impairing its safety function, and an optical scanning type photoelectric switch is provided with a muting function settable by the user, which is a function of temporarily invalidating sensing of part or the whole of a protection area, and is provided with two output systems, with respect to each of which the muting function is settable and on each output of which an inspection signal is superimposed at a different timing in a time-division manner.
