Abstract: Provided is a photoelectric sensor capable of being securely joined to a housing while being sufficiently resistant to dirt. A housing 12 of a photoelectric sensor 10 has an opening 121 which allows passage of at least one of light from a light projecting unit 14 and light to a light receiving unit 16, and is provided with a cover lens 50 which covers the opening 121 and is optically transmissive. The cover lens 50 is joined to an edge portion 121a of the housing 12 defining the opening 121. An outer surface 51 of the cover lens 50 is provided with antifouling coating 61. An inner surface 52 of the cover lens 50 has a joint portion 52a which is in contact with the edge portion 121a and is not provided with the antifouling coating 61.

Abstract: A sensor and an electronic device are provided. The sensor includes a setting part and a seal ring in an annular shape. The setting part changes a setting of a sensor main body. The seal ring is provided to surround a shaft of the setting part and seals a gap between the shaft and a housing. The seal ring has a curved surface part and a pair of end parts. The curved surface part is curved convexly in a cross-sectional view. The pair of end parts have a shape different from the curved surface part and extend in an axial direction of the seal ring, on two sides of the curved surface part in the axial direction of the seal ring.
