WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an

QMT42 Series Fixed-Field Sensors
Fixed-Field Sensing – Theory of Operation
The QMT...FF... 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 1 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 QMT...FF... sensors is fixed at 500, 750, 1000, 1500, or 2000 millimeters (20, 30, 39, 59, or
79 inches 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).

Figure 1. Fixed-Field Concept
Figure 2. Fixed-Field Sensing Axis
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 2 on page 2. The sensing axis becomes important in certain
situations, such as those illustrated in Figure 3 on page 3 and Figure 4 on page 3.
Placement
An object beyond the cutoff distance, either stationary (and when positioned as shown in Figure 3 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 4 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.

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 millimeters (79 inches) using a 90% reflectance white test card. In other words, the
cutoff point for the black target is 1800 millimeters (71 inches).
