Q60AFV Overview

The Q60AFV 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.)

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 Q60AFV 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.

The cutoff distance for Q60AFV sensors is adjustable from 200
to 1000 millimeters (8" to 40"). 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.

Sensor Setup

Setting the Cutoff Distance

The cutoff distance for Q60AFV sensors may be adjusted between 200 mm and
1000 mm (8" to 40").

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).

NOTE: Setting the cutoff distance adjustment screw to its maximum clockwise

position places the receiver lens directly in front of the receiver elements and
results in the Q60 performing as a long-range diffuse sensor.

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 1 m cutoffs.
Maximum excess gain for a 200 mm cutoff occurs at a lens-to-object distance of
about 150 mm, and for a 1 m cutoff, at about 400 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.
