Figure 13 Photo-electric cells
Photo-electric or inductive sensors, depending on version, are used for de-
tecting that product is positioned in the lift cage.
The photo-electric sensor type is retro-reflective, thus the light beam is re-
flected by a reflector on the opposite side of conveyor back to sensor, mak-
ing the detection of product less sensitive to colour differences of product.
The stop position of conveyed item, due to sensor position, is such that the
conveyed item does not reach to the end of lift cage conveyor.
RTI elevator version
For RTI elevators, photo-electric cells are used, mounted at fixed positions
in the elevator frame.
