In case the elevator door is made of glass or a shiny material (e.g. mirror), the door may not be detected by the
sensor during closure. For these applications, place a piece of reflective tape on the inner side of the elevator cab
door that passes in front of the sensor as the door closes (see figure 4 and 5).

To ensure the reflective tape is positioned within the
sensor’s field of view , the Y distance measurement is
used.
For 30° mounting brackets, use the following formula:
Distance Y = 1.7 * horizontal distance x
For 35° mounting brackets, use the following formula:
Distance Y = 1.4 * horizontal distance x
