A model with a QD connector requires an optional mating cable. See page 6 for more information. The excess gain curves above show excess gain vs. sensing distance for M18 Series fixed-field sensors with 25-, 50- and 100-millimeter cutoffs. Maximum excess gain for the 25-mm models occurs at a lens-to-object distance of about 7 mm; for the 50-mm models, at about 10 mm; and for the 100-mm models, at about 20 mm. Sensing at or near these distances will make maximum use of each sensor’s available sensing power. Backgrounds and background objects must always be placed beyond the cutoff distance. These excess gain curves were generated using a white test card of 90% reflectance. Banner Engineering Corp. • Minneapolis, U.S.A. Website: http://www.baneng.com • Tel: 888.373.6767 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. 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 20, 40 and 70 mm (for 25-, 50- and 100-mm cutoff models, respectively). Objects with reflectivity greater than 90% return more light to the sensor. For this reason, highly reflective backgrounds or background objects such as mirrors, polished metal, and other sources of specular reflections require special consideration. If it is necessary to use a highly reflective background, it should be placed as far beyond the cutoff distance as possible and angled to direct reflected light away from the sensor (see page 4). page 3 EZ-BEAM M18 Series Sensors EZ-BEAM M18 Series Fixed-Field Sensor Setup Tips General 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 (see page 3). 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. In the drawings and discussion on this page, 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 Figures 2, 3, and 4, these elements align vertically; in Figure 5, they align horizontally. Note how the position of the tabs on the front of the sensor helps to define the sensing axis of the sensor (Figure 1, right). The sensing axis becomes important in situations like those illustrated in Figures 4 and 5 below. 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 (R1) than to the far detector (R2). The result is a false ON condition (Figure 2). Use of a diffusely-reflective (matte) background will cure this problem. Other possible solutions are to either angle the sensor or angle the background (in any plane) so that the background does not reflect back to the sensor (see Figure 3). An object beyond the cutoff distance, either moving or stationary (and when positioned as shown in Figure 4), can cause unwanted triggering of the sensor because it reflects more light to the near detector than to the far detector. Remedy the problem easily by rotating the sensor 90° (Figure 5) 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 moving perpendicular to the sensor face, or by an object moving through the off-center position shown in Figure 4. 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 5) will solve the problem. Fixed Sensing Field M18FF Sensor E R2 R1 Sensing Axis 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.
