Abstract
A photo-optic attachment for a conveyor roller comprises an end cap mountable on the conveyor roller and a photo-optic disc mountable on the end cap. The end cap includes an outwardly facing surface having a raised boss. The photo-optic disc includes an opening sized and shaped to register with the boss on the end cap. The photo-optic disc is retained on the end cap by a spring clip which is insertable over the end of the boss. The shape of the boss and the opening in the photo-optic disc is such to prevent relative rotation between the end cap and the photo-optic disc thereby providing a more accurate measure of the conveyor roller speed.
