Their high excess gain and fixed-field technology allow detection of 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. Fixed-Field Sensing – Theory of Operation The T30 Fixed-Field 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 1 on page 2. If the near detector's (R1) light signal is stronger than the far detector's (R2) light signal (see object A in the Figure below, closer than the cutoff distance), the sensor responds to the object. If the far detector's (R2) light signal is stronger than the near detector's (R1) light signal (see object B in the Figure below, beyond the cutoff distance), the sensor ignores the object. 1 Integral 2 m (6.5 ft) unterminated cable models are listed. • To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, T306E W/30. • To order the 4-pin M12/Euro-style integral quick disconnect model, add the suffix "Q" to the model number. For example, T306EQ. • Models with a quick disconnect require a mating cordset. Original Document 121524 Rev.

Objects lying beyond the cutoff distance are usually ignored, even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see Background Reflectivity and Placement on page 2). Receiver Elements Cutoff Distance Object B or Background Object A Lenses Near R1 Detector Far R2 Detector Emitter E R1 R2 Sensing Range Sensing Axis E Object is sensed if amount of light at R1 is greater than the amount of light at R2 Figure 1. Fixed-Field Concept Figure 2. Fixed-Field Sensing Axis In the drawings and information provided 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 2 on page 2. The sensing axis becomes important in certain situations, such as those illustrated in Figure 5 on page 3 and Figure 6 on page 3. Sensor Setup Sensing Reliability For highest sensitivity, position the target for sensing at or near the point of maximum excess gain. Maximum excess gain for all models occurs at a lens-to-object distance of about 40 mm (1.5 in). 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 3 on page 3). 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 4 on page 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 on page 3), 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 6 on page 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: +1-763-544-3164 P/N 121524 Rev.

A reflective background object in this position or moving across the sensor face in this axis is ignored. Figure 5. Object Beyond Cutoff - Problem Figure 6. Object Beyond Cutoff - Solution 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 is slightly shorter than for higher reflectance targets. 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 190 mm (7.5 inch) for the 200 mm (8 inch) cutoff model, for example; and 190 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.
