Abstract
A multi-beam photoelectric sensor is disclosed which can be fabricated by selecting the length of a light projection/light-receiving columnar member and the number and pitches of optical axes in accordance with the width of a hazardous area of an object or the diameter of the minimum object to be detected. A projector string or a photo-detector string includes an optical module string having an alignment of a plurality of optical modules with an optical system for one optical axis, a light projection circuit for one optical axis and a plurality of flip-flops corresponding to one stage of a shift register, integrated with each other, and a flat cable. The flip-flops in the adjacent optical modules are connected in cascade by the adjacent module conduction wires thereby to make up a shift register. The optical modules making the optical module string are sequentially activated by the data sequentially sent by the shift register.
