Abstract

Provided is a photoelectric sensor (1; 1a; 1b; 1c) that makes fine adjustment of a sensitivity parameter easy. The photoelectric sensor (1; 1a; 1b; 1c) includes received light signal adjustment means (22) and sensitivity parameter adjustment means (25). The received light signal adjustment means (22) includes an operation unit (31) and a first adjustment unit (41). The operation unit (31) adjusts, by its position being operated in an operable rang, at least one sensitivity parameter of projection light power and received light gain within a predetermined range. The first adjustment unit (41) adjusts the at least one sensitivity parameter so that a ratio of the maximum value to the minimum value of the received light signal value is not greater than 2.6. The sensitivity parameter adjustment means (25) includes a trigger input reception unit (32) and a second adjustment unit (42). The second adjustment unit (42) adjusts at least one of the projection light power, the received light gain, and the threshold when the trigger input reception unit (32) has received a trigger input while the operation unit (31) is at a predetermined position in a state in which the detection object (6) is not present in the detection region (5).
