A sensor device (1) includes: a casing (10) provided with an opening (12); a cover member (24) covering the opening (12); a gasket (91) interposed between the cover member (24) and the casing (10); and a fixing cover (18) which fixes both the gasket (91) and the cover member (24) to the casing (10). A plurality of welded portions (WP) bonding the casing (10) and the fixing cover (18) together are provided in a region outside the cover member (24) such that the welded portions (WP) are distant from each other.
摘要:
the present application relates to a sensor device (1), which includes a body case (10A) provided with an opening (14), and a body cover (10B) assembled to the body case (10A) to cover the opening (14). The body cover (10B) has at an outer peripheral portion thereof an overlapping region (OR) overlapping a portion of the body case (10A) located at a peripheral edge of the opening (14). The body cover (10B) is fixed to the body case (10A) by providing a welded portion (WP) surrounding the opening (14) using laser-welding at a portion distant from an end surface (10b) of the body cover (10B) in a boundary of the overlapping region (OR) of the body cover (10B) and a portion of the body case (10A) overlapping the overlapping region (OR).
摘要:
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.
摘要:
A housing of a photoelectric sensor has a front surface having a light projecting/receiving surface, a rear surface, a top surface adjacent to the front surface and extending in a direction orthogonal to the front surface and the rear surface, and an inclined surface inclined with respect to and connecting the top surface and the rear surface. On the top surface, a teach button that receives an input operation from outside to set a threshold value and an indicator that displays a detection result of the object being detected are provided in order from the side of the inclined surface. On the inclined surface, an adjustment button that receives an input operation from outside to finely adjust the threshold value is provided. A distance between the teach button and the adjustment button is larger than a distance between the teach button and the indicator.

Provided are a sensor and electronic device that enable reductions in the sealing performance of a sealant to be minimized. The sensor 10 comprises a setting part 18 which changes settings of a main sensor unit, and an annular seal ring 60, which is disposed so as to encircle a shaft 18b of the setting part 18, and seals a gap between the shaft 18b and a housing 12. The seal ring 60 comprises a curved surface section 61 which curves outward as seen in cross section, and a pair of end sections 62a, 62b, on both sides of the curved surface section 61 in the axial direction of the seal ring 60, which have a different shape from the curved surface section 61 and extend in the axial direction of the seal ring 60.
