Photoelectric sensor housing assembling method and photoelectric sensor

摘要: A housing assembly method for bonding through causing a first member and second member, which form tightly sealed that contains sensing element, to be mutually abutting. resin material laser beam passes is used as the absorbs of piece. With surfaces these members abutting each other, having diameter smaller than width directed towards from piece side weld together while leaving non-welded portions between surfaces.
