Usage notes
(1) The lens consists of polycarbonate which may be damaged by some chemicals. Therefore care should be taken to prevent chemicals from touching the lens surface. (2) This reflective photosensor should not be cleaned with detergents since the lens is an optical component made with polycarbonate resin. Dust and debris should be wiped off using an air blower or soft cloth, taking care not to scratch the lens. (3) Do not apply mechanical stress (e.g., pulling, bending, twisting, spreading) to the lead bases.
