<p>PURPOSE:To provide a limited reflection side view type photoelectric switch in which optical axis adjustment is unnecessary and the presence of a body in a narrow space is easily detected. CONSTITUTION:Fixing frames 21a, 22, 21b for fixing prism lenses 10a, 10b are integrally formed in a holding member 20. Recesses 23a, 24a, 24b, 23b fitting to projections 16 for positioning prism lenses 10a, 10b are formed in the fixing frames 21a, 22, 21b. The prism lenses 10a, 10b are positioned in the holding member 20 so that a second convex lens 15 formed on a second incident/ outgoing surface is faced toward slant forward. Optical fibers 40a, 40b are fixed to the lower part of a first convex lens formed on a first incident/outgoing surface of the prism lenses 10a, 10b.</p> |
