A Q60 Series Adjustable-Field Sensors Q60AF Overview The Q60AF sensor is a full-featured adjustable-field sensor. 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 2-turn adjustment screw on the sensor top (Figure 1). A rotating pointer indicates the relative cutoff position. (The indicator moves clockwise to show increasing distance.) ON/OFF Delay Push Buttons and Indicators Indicators Below Also Function as a 5-Segment Light Bar During Delay Selection Modes Cutoff Adjustment Screw Light Sensed Indicator Light Operate Selected Push Button Lockout Indicator Two push buttons (ON Delay and OFF Delay) are used to set the output delay options, to toggle between light and dark operate modes and to lock out the push buttons for security purposes. These functions also may be accomplished using the remote wire. Seven LED indicators show, during RUN mode, the sensor configuration and operating status. During Delay Configuration, 5 of the LEDs combine to form a single light bar that indicates relative ON or OFF delay time. Adjustable-Field Sensing -- Theory of Operation In operation, the Q60AF 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). 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. Dark Operate Selected Output Conducting (Bi-color Amber/Green) Figure 1. Q60 features Cutoff Distance Receiver Elements Near R1 Detector Lenses Far R2 Detector The cutoff distance for Q60AF sensors is adjustable from 200 to 2000 millimeters (8" to 80"). 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, page 3). In the drawings and discussion on this page and page 3, 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 3). The sensing axis becomes important in certain situations, such as those illustrated in Figures 8 and 9. Object B or Background Object A E Sensing Range Figure 2. Adjustable field sensing concept 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.

Setting the cutoff distance Sensing Field Strong Direct Reflection to R1 R1 R2 E Cutoff Distance Core of Emitted Beam Reflective Background E = Emitter R1 = Near Detector R2 = Far Detector To maximize contrast, position the lightest possible background to be used, at the closest position it will come to the sensor during use (Figure 4). Using a small screwdriver in the adjustment screw, adjust the cutoff distance until the threshold is reached and the green Light Sensed indicator changes state. (If the indicator never comes ON, the background is beyond the maximum sensing cutoff and will be ignored.) Note the position of the rotating cutoff position indicator at this position. Then repeat the procedure, using the darkest target, placed in its most distant position for sensing. Adjust the cutoff so that the indicator is midway between the two positions (Figure 5). Sensing Reliability 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 excess gain curves on page 1 show excess gain vs. sensing distance for 200 mm and 2 m cutoffs. Maximum excess gain for a 200 mm cutoff occurs at a lens-to-object distance of about 150 mm, and for a 2 m cutoff, at about 500 mm. 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. 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 6). Use of a diffusely-reflective (matte) background will cure this problem. Other possible solutions are to angle either the sensor or the background (in any plane) so that the background does not reflect back to the sensor (see Figure 7). An object beyond the cutoff distance, either moving or stationary (and when positioned as shown in Figure 8), can cause unwanted triggering of the sensor because it reflects more light to the near detector than to the far detector. The problem is easily remedied by rotating the sensor 90 (Figure 9) to align the sensing axis horizontally. The object then reflects the R1 and R2 fields equally, resulting in no false triggering.

Object beyond cutoff distance -- solution page 3 Q60 Series Adjustable-Field Sensors 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 Figure 10). This behavior is known as color sensitivity. 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% reflective white test card. For example, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is adjusted for 2000 mm (80") using a 90% reflectance white test card. In other words, the cutoff point for the black target is 1800 mm (71") for this setting. Setting the Output Delay The output of the Q60AF sensor may be delayed between 0.008 and 16 seconds, in any of 72 increments. Delay is indicated on the 5-segment light bar using single LED segments or combinations of them, in varying stages of intensity. Major increments, displayed by a single full-intensity LED, are shown in Figure 13. Percent Deviation -2 -3 -4 -5 -6 18% Gray Card 6% Black Card -7 -8 -9 -10 200 400 600 800 1000 1200 1400 1600 1800 2000 1600 1800 2000 Cutoff Setting (90% White Card) Figure 10. Cutoff point deviation Minimum Range with a 6% Black Card (mm) The excess gain curves on page 1 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. 0 -1 150 140 130 120 110 100 90 80 70 60 50 200 400 600 800 1000 1200 1400 Cutoff Distance (mm) with 90% White Card DO DO DO LO DO LO 3.0 2.5 2.0 1.5 1.0 0.5 0 200 400 600 800 1000 1200 1400 1600 1800 2000 Cutoff Setting (mm) with 90% White Card DO LO 16 seconds SIG 72 SIG 56 4.0 seconds LO 40 1.00 second SIG 0.250 second SIG 24 DO 8 0.062 second LO No Delay LO 0 LED Status SIG Delay Time SIG Step # Hysteresis (% of Cutoff) with 6% Black Card Figure 11.
