Their high excess gain and fixed-field technology allow them to detect objects of low reflectivity, while ignoring background surfaces. The cutoff distance is fixed. Backgrounds and background objects must always be placed beyond the cutoff distance. The S18FF compares the reflections of its emitted light beam (E) from an object back to the sensor’s two differently aimed detectors, R1 and R2. If the near detector (R1) light signal is stronger than the far detector (R2) light signal (see object A, closer than the cutoff distance), the sensor responds to the object. If the far detector (R2) light signal is stronger than the near detector (R1) light signal (see object B, beyond the cutoff distance), the sensor ignores the object. Receiver Elements Near R1 Detector Cutoff Distance Object B or Background Object A Lenses Far R2 Detector Emitter E Sensing Range Object is sensed if amount of light at R1 is greater than the amount of light at R2 Figure 1. Fixed-field concept The cutoff distance for model S18FF sensors is fixed at 25, 50 or 100 millimeters (1 in, 2 in, or 4 in). Objects lying beyond the cutoff distance usually are ignored, even if they are highly reflective. However, it is possible to falsely detect a background object, under certain conditions (see Background Reflectivity and Placement). In the drawings and discussion on these pages, 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 (p. 2)). The sensing axis becomes important in certain situations, such as those illustrated in Figure 5 (p. 3) and Figure 6 (p. 3). Sensor Setup Sensing Reliability 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. For highest sensitivity, position the target object for sensing at or near the point of maximum excess gain. The excess gain curves for these products are shown. Maximum excess gain for the 25 mm models occurs at a lens-to-object distance of about 7 mm; for 50 mm models, at about 10 mm; and for the 100 mm models, at about 20 mm. Sensing at or near this distance will make maximum use of each sensor’s available sensing power. The background must be placed beyond the cutoff distance. (Note that the reflectivity of the background surface also may affect the cutoff distance.) Following these two guidelines will improve sensing reliability. E Sensing Axis R2 R1 Figure 2. Fixed-field sensing axis Background Reflectivity and Placement Avoid mirror-like backgrounds that produce specular reflections. False sensor response will occur if a background surface reflects the sensor’s light more strongly to the near detector, or “sensing” detector (R1), than to the far detector, or “cutoff” detector (R2). The result is a false ON condition (see Figure 3 (p. 3)). To cure 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 4 (p. 3)). 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 5 (p. 3)), or moving past the face of the sensor in a direction perpendicular to the sensing axis, can 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 6 (p. 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 www.bannerengineering.com - Tel: + 1 888 373 6767 P/N 121522 Rev.

Object Beyond Cutoff - Problem Figure 6. Object Beyond Cutoff - Solution A reflective background object in this position or moving across the sensor face in this axis and direction may cause false sensor response. A reflective background object in this position or moving across the sensor face in this axis will be ignored. Color Sensitivity The effects of object reflectivity on cutoff distance, though small, may be important for some applications. It is expected that at any given cutoff setting, the actual cutoff distance for lower reflectance targets will be slightly shorter than for higher reflectance targets (see Performance Curves). This behavior is known as color sensitivity. 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 horizontal graph line at excess gain = 10. An object of this reflectivity results in a far limit cutoff of approximately 20 mm (0.8 inches), for the 25 mm (1 inch) cutoff model for example; thus 20 mm represents the cutoff for this sensor and target. These 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.
