The high excess gain of these sensors makes it possible for them to detect objects of low reflectivity. The fixed-field design makes them ideal for detecting a part or surface that is directly in front of another surface, while ignoring the surface in the background. Installation In the drawings and discussion in Excess Gain on page 4 and in Background Reflectivity and Placement on page 2, 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. In Figure 1 on page 2, Figure 2 on page 2, and Figure 3 on page 2, these elements align vertically; in Figure 4 on page 2, they align horizontally. Note how the pattern on the sensor’s lens helps to define the sensing axis of the sensor (Figure 6 on page 4). The sensing axis becomes important in situations like those illustrated in Figure 3 on page 2 and Figure 4 on page 2. 1 Standard 2 m (6.5 ft) cable models are listed. • To order 9 m (30 ft) cable: add suffix "W/30" (for example, Q406E W/30). • To order 4-pin Euro-style QD models: add suffix "Q" (for example, Q406EQ). A model with a QD connector requires a mating cable. Original Document 116167 Rev.

A false sensor response occurs if a background surface reflects the sensor’s light more to the near detector (R1) than to the far detector (R2). The result is a false ON condition (Figure 1 on page 2). To correct this problem, use a diffusely reflective (matte) background, or angle either the sensor or the background (in any plane) so the background does not reflect light back to the sensor (see Figure 2 on page 2). Position the background as far beyond the cutoff distance as possible. An object beyond the cutoff distance, either stationary (and when positioned as shown in Figure 3 on page 2), 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. The problem is easily remedied by rotating the sensor 90° (Figure 4 on page 2) to align the sensing axis horizontally. 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. Unwanted triggering of the sensor from an object beyond the cutoff can also be caused by attempting to sense a small object that is moving perpendicular to the sensor face, or by an object moving through the off-center position shown in Figure 3 on page 2. Making the object larger, centering the sensor relative to the object, or rotating the sensor to place the sensing axis perpendicular to the longer dimension of the object (Figure 4 on page 2) will solve the problem.

Excess Gain The excess gain curves for these products are available on the Banner website. They show excess gain versus sensing distance for sensors with 200 mm, 400 mm, and 600 mm (8 in, 16 in, and 24 in) cutoffs. Maximum excess gain for all models occurs at a lens-to-object distance of about 40 mm (1.57 in). Sensing at or near this distance makes maximum use of each sensor’s available sensing power. Receiver Elements Near R1 Detector Cutoff Distance Object B or Background Object A Lenses Far R2 Detector Backgrounds and background objects must always be placed beyond the cutoff distance. The excess gain curves were generated using a white test card of 90% reflectance. Objects with reflectivity of less than 90% 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. Emitter Sensing Range Object is sensed if amount of light at R1 is greater than the amount of light at R2 Figure 5. Fixed-field Concept The effects of object reflectivity on cutoff distance, though small, may be important for some applications. Sensing of objects of less than 90% reflectivity causes the cutoff distances to be “pulled” slightly closer to the sensor. For example, an excess gain of 1 for an object that reflects 1/10 as much light as the 90% white card is represented by the heavy horizontal graph line at excess gain = 10. An object of this reflectivity results in far limit cutoffs of approximately 190 mm, 250 mm, and 390 mm (7.48 in, 9.84 in, and 15.4 in) for the 200 mm, 400 mm, and 600 mm (8 in, 16 in, and 24 in) cutoff models, respectively. For highest sensitivity, the sensor-to-object distance should be such that the object will be sensed at or near the point of maximum excess gain. The background must be placed beyond the cutoff distance. Following these two guidelines makes it possible to detect objects of low reflectivity, even against close-in reflective backgrounds. 4 E R1 R2 Sensing Axis E As a general rule, the most reliable sensing of an object approaching from the side occurs when the line of approach is parallel to the sensing axis.
