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 top of the sensor. A rotating pointer indicates the relative cutoff position. The indicator moves
clockwise to show increasing distance.
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 (available on
some models).
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.
Note: When an object approaches from the side, the most reliable sensing usually occurs when the line of approach
is parallel to the sensing axis.
1 To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, Q60BB6AF2000 W/30. Models with a quick
disconnect require a mating cordset.

Adjustable-Field Sensing—Theory of 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 1 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).

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 7
on page 4 and Figure 8 on page 4.

Dis
To maximize contrast, 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 green Light Sensed
indicator changes state. If the indicator never turns 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.

Q60AF Sensors
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 show excess gain versus 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. 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 5 on page 4).
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 6 on page 4). 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 7 on page 4), 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 8 on page 4). 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.

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.
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.

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 (78.7in)
using a 90% reflectance white test card. In other words, the cutoff point for the black target is 1800 mm (70.9 in) for this setting.
