It provides background suppression sensing capability for small or difficult-to-reach areas. Models are available with a visible red LED sensing beam, or one of two visible red lasers (see Models on page 1). These adjustable-field sensors are able to detect objects of relatively low reflectivity, while ignoring other objects in the background (beyond the cutoff point). The cutoff distance is mechanically adjustable, using the 5-turn adjustment screw on the sensor top. Backgrounds and background objects must always be placed beyond the cutoff distance. 1. Green: Power Indicator (Flashes for Output Overload) 2. Amber: Light Sensed Indicator (Flashes for Low Gain Conditions) 3. Cutoff Point Adjustment Screw Figure 1. Sensor features Adjustable-Field Sensing — Theory of Operation The sensor 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 2 on page 2). 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, object beyond the cutoff distance), the sensor ignores the object. The cutoff distance for these sensors is adjustable. Objects lying beyond the cutoff distance 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 on page 4). Cutoff Distance Receiver Elements Object B or Background Object A Near Detector R1 Lenses Far Detector R2 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 6 on page 4). The sensing axis becomes important in certain situations, such as those illustrated in Figure 10 on page 5 and Figure 11 on page 5. E Sensing Range Figure 2. Adjustable field sensing concept 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 the cutoff point deviation graphs). This behavior is known as color sensitivity. 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. In the cutoff point deviation graphs, the percentage of deviation indicates a change in the cutoff point for either 18% gray or 6% black targets, relative to the cutoff point set for a 90% reflectance white test card. For example, in Figure 3 on page 3, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is adjusted for 100 mm (4 in) using a 90% reflectance white test card. In other words, the cutoff point for the black target is 90 mm (3.6 in) for this setting. 2 www.bannerengineering.com - Tel: +1-763-544-3164 P/N 66981 Rev.

To properly set the cutoff point, position the lightest possible background to be used, at the closest position it will come to the sensor during use. Using a small screwdriver in the adjustment screw, adjust the cutoff distance until the threshold is reached and the yellow Light Sensed indicator changes state. (If the indicator never comes ON, the background is beyond the maximum sensing distance and will be ignored.) Repeat the procedure, using the darkest target, placed in its most distant position for sensing. Adjust the cutoff approximately midway between the two positions (Figure 7 on page 4). Sensing Axis Receiver Elements Emitter When an object approaches from the side, the most reliable sensing usually occurs when the line of approach is parallel to the sensing axis. Figure 6. Sensing Axis Target Background R1 R2 E Cutoff Distance Figure 7. Set cutoff distance approximately midway between the farthest target and the closest background Sensing Reliability For highest sensitivity, position the target for sensing at or near the point of maximum excess gain. See the Performance Curves section for the excess gain curves. Maximum excess gain for model QS18VN6AF100 at a 20 mm cutoff occurs at a lens-to-object distance of about 7 mm, for example. Sensing 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. Note that the reflectivity of the background surface also may affect the cutoff distance. Following these guidelines improves sensing reliability. Background Reflectivity and Placement Avoid mirror-like backgrounds that produce specular reflections. 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 8 on page 5). Correct 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 9 on page 5). 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 10 on page 5), 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 11 on page 5). 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. 4 www.bannerengineering.com - Tel: +1-763-544-3164 P/N 66981 Rev.
