## Fixed-Field Sensing – Theory of Operation The QMT42FF compares the reflections of its emitted light beam (E) from an object back to the sensor's two differently aimed detectors, R1 and R2. See "Figure: Fixed-Field Concept" on page 2. If the near detector's (R1) light signal is stronger than the far detector's (R2) light signal (see object A in the Figure below, closer than the cutoff distance), the sensor responds to the object. If the far detector's (R2) light signal is stronger than the near detector's (R1) light signal (see object B in the Figure below, beyond the cutoff distance), the sensor ignores the object. The cutoff distance for model QMT42FF sensors is fixed at 500, 750, 1000, 1500, or 2000 mm (20, 30, 39, 59, or 79 in) Objects lying beyond the cutoff distance are ignored, even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see "Placement" on page 2). **==> picture [500 x 254] intentionally omitted <==** **----- Start of picture text -----**

In the drawings and information provided in this document, the letters E, R1, and R2 identify how the sensor's three optical elements (Emitter "E", Near Detector "R1", and Far Detector "R2") line up across the face of the sensor. The location of these elements defines the sensing axis, see "Figure: Fixed-Field Sensing Axis" on page 2. The sensing axis becomes important in certain situations, such as those illustrated in "Figure: Object Beyond Cutoff - Problem" on page 3 and "Figure: Object Beyond Cutoff - Solution" on page 3. ## Placement An object beyond the cutoff distance, either stationary (and when positioned as shown in "Figure: Object Beyond Cutoff - Problem" on page 3), or moving past the face of the sensor in a direction perpendicular to the sensing axis, may cause unwanted triggering of the sensor if more light is reflected to the near detector than to the far detector. Correct the problem by rotating the sensor 90° ("Figure: Object Beyond Cutoff - Solution" on page 3). The object then reflects the R1 and R2 fields equally, resulting in no false triggering. A better solution, if possible, may be to reposition the object or the sensor. 2 | 6 © Banner Engineering Corp.

## Cutoff Point Deviation The percentage of deviation indicates a change in the cutoff point for either 18% gray or 6% black targets, relative to the cutoff point for a 90% reflective white test card. As an example, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is 2000 mm (79 in) using a 90% reflectance white test card. In other words, the cutoff point for the black target is 1800 mm (71 in). **==> picture [279 x 181] intentionally omitted <==** **----- Start of picture text -----**
