Their high excess gain and fixed-field technology allow detection of objects of low reflectivity, while ignoring background surfaces. The cutoff distance is fixed. s and background objects must always be placed beyond the cutoff distance. Only standard 2 m (6.5 ft) cabled models are listed. To order the 9 m (3 ft) integral cable model, add suffix W/3 to the model number (for example, Q3 W/3). To order the 5-pin integral M2/uro-style quick disconnect (QD), add suffix Q (for example, Q3Q). 2 Polarized and ranges are specified using a model BRT-84 retroreflector.

2 WORLD-BM Q3 eries ensor (D Voltage) Fixed-Field ensing Theory of Operation The WORLD-BM Q3 eries ensor compares the reflections of its emitted light beam () from an object back to the sensor's two differently aimed detectors, R and. ee Figure on page 2. f the near detector's (R) light signal is stronger than the far detector's () light signal (see object in the Figure below, closer than the cutoff distance), the sensor responds to the object. f the far detector's () light signal is stronger than the near detector's (R) light signal (see object B in the Figure below, beyond the cutoff distance), the sensor ignores the object. The cutoff distance for the Q3 is fixed at 2, 4, or 6 mm (8, 6, or 24 in). Objects lying beyond the cutoff distance are usually ignored, even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see Reflectivity and Placement on page 2). ear Detector Receiver lements R Lenses Object utoff Object B or Far Detector mitter ensing Range R ensing xis Object is sensed if amount of light at R is greater than the amount of light at Figure. Fixed-Field oncept Figure 2. Fixed-Field ensing xis n the drawings and information provided in this document, the letters, R, and identify how the sensor's three optical elements (mitter "", ear Detector "R", and Far Detector "") 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 5 on page 3 and Figure 6 on page 3. onfiguring a ensor ensing Reliability For highest sensitivity, position the target for sensing at or near the point of maximum excess gain. Refer to the Performance urves for the excess gain. ensing at or near this distance makes the maximum use of each sensor s available sensing power. The background must be placed beyond the cutoff distance. ote that the reflectivity of the background surface also may affect the cutoff distance. Following these guidelines improves sensing reliability. Reflectivity and Placement void mirror-like backgrounds that produce specular reflections. false sensor response occurs if a background surface reflects the sensor's light more to the near detector (R) than to the far detector (). The result is a false O condition (Figure 3 on page 3). orrect this problem by using a diffusely reflective (matte) background, or angling either the sensor or the background (in any plane) so the background does not reflect light back to the sensor (Figure 4 on page 3). Position the background as far beyond the cutoff distance as possible. n object beyond the cutoff distance, either stationary (and when positioned as shown in Figure 5 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. orrect the problem by rotating the sensor 9 (Figure 6 on page 3). The object then reflects the R and fields equally, resulting in no false triggering. better solution, if possible, may be to reposition the object or the sensor Tel: P/ 965 Rev.

Object Beyond utoff - olution olor ensitivity The effects of object reflectivity on cutoff distance, though small, may be important for some applications. t is expected that at any given cutoff setting, the actual cutoff distance for lower reflectance targets is slightly shorter than for higher reflectance targets. This behavior is known as color sensitivity. For example, an excess gain of for an object that reflects / as much light as the 9% white card is represented by the horizontal graph line at excess gain =. n object of this reflectivity results in a far limit cutoff of approximately 9 mm (7.5 in) cutoff model, for example; and 9 mm (7.5 in) represents the cutoff for this sensor and target. These excess gain curves were generated using a white test card of 9% reflectance. Objects with reflectivity of less than 9% reflect less light back to the sensor, and thus require proportionately more excess gain in order to be sensed with the same reliability as more reflective objects. When sensing an object of very low reflectivity, it may be especially important to sense it at or near the distance of maximum excess gain.
