The principle of photoswitch :the projector will judge and react on the basis of light beam from the projector which is interdicted by object or emitted partly.
Diffuse refelection type pgotoelectric switch integrates the transmitter and the receiver. Light reflected by the pgotoelectric switch is reflected back to the receiver by the detected object.
Retroreflective type photoelectric switch also integrates the transmitter and the receiver .
Its difference from other models is that reflector is used to reflect light to the photoelectric switch .
Though the object between the photoelectric switch and reflector can reflect the light,it's much less efficient than the refletor so as to cut down reflected light
