The present invention maintains sealing of the housing over a long period of time. A multiple-optical-axis photoelectric sensor () includes a light projector () and a light receiver () whose external forms are each formed by a housing () including an outer case () constituted by a main body case () and a first cap member (), a light-transmitting plate (), a first pressing member (A), second pressing members (B), a first adhesive tape (A), and second adhesive tapes (B). The first cap member () has a supporting part () provided on its inner side, and an elastic member () is provided between the second pressing member (B) and a portion of the light-transmitting plate () supported by the supporting part (). The light-transmitting plate () is pressed toward the first cap member () via the elastic member ().

Multi optical axis sensor

The present invention achieves a multiple-optical-axis photoelectric sensor which can be assembled with reduced effort. A multiple-optical-axis photoelectric sensor () includes a light projector () and a light receiver () each having an outer shape defined by a housing () including: an outer case (); a light-transmitting plate (); and a pressing member (). Supporting parts () are provided at respective inner surfaces of side plates of the outer case. Extending parts () are provided at end parts of the corresponding side plates. The pressing member is configured to press the light-transmitting plate against the supporting parts by being attached to the respective extending parts.

Multiple-optical-axis photoelectric sensor

A light projector and a light receiver each includes a case body, a light transmission plate closing an opening in a front face of the case body, and a pair of caps closing openings in end faces of the case body. The case body includes first supports supporting side edges of the light transmission plate, the caps respectively include second supports supporting ends of the light transmission plate, the light transmission plate is supported by the first supports and the second supports with an elastic member interposed between the light transmission plate and the first and second supports, and the cap is fixed to the case body while the seal member abutting on the end face of the case body is interposed between the cap and the case body. A cured liquid sealing agent is interposed between leading ends of the seal member and the elastic member.
