QS18VxAF Mechanically Adjustable Background Suppression Sensor 

## Overview 

The QS18 Adjustable-Field Sensor are a full-featured sensor in a miniature package. It provides background suppression sensing capability for small or difficult-to-reach areas. Models are available with a visible red LED sensing beam, or one of two visible red lasers (see "QS18VxAF Models" on page 1). 

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 5-turn adjustment screw on the sensor top. Backgrounds and background objects must always be placed beyond the cutoff distance.

## Adjustable-Field Sensing — Theory of Operation 

The 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. 

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 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 "Setting the

Cutoff Distance" on page 4). The sensing axis becomes important in certain situations, such as those illustrated in "Figure: Object Beyond Cutoff - Problem" on page 5 and "Figure: Object Beyond Cutoff - Solution" on page 5. 

## 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 the cutoff point deviation graphs). This behavior is known as color sensitivity. 

The 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. 

In the cutoff point deviation graphs, 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% reflectance white test card. 

For example, in "Figure: QS18AF100 minimum separation between object and background" on page 3, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is adjusted for 100 mm (4 in) using a 90% reflectance white test card. In other words, the cutoff point for the black target is 90 mm (3.6 in) for this setting.

QS18VxAF Mechanically Adjustable Background Suppression Sensor 

In light operate (LO) mode, the output is ON when the target returns the same or more light to the sensor and OFF when the sensor detects less light than the configured/taught target. 

In adjustable field sensing modes, light operate is active when the target is present and dark operate is active when the target is absent.

The cutoff distance for the QS18AF models may be adjusted between 20 mm and 100 mm (0.8 in to 4 in); for QS18LAF models, between 30 mm and 150 mm (1.2 in to 6 in); and for QS18LAF250 models, between 50 mm and 250 mm (2 in to 10 in). 

To properly set the cutoff point, 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 yellow Light Sensed indicator changes state. (If the indicator never comes ON, the background is beyond the maximum sensing distance and will be ignored.) Repeat the procedure, using the darkest target, placed in its most distant position for sensing. Adjust the cutoff approximately midway between the two positions ("Figure: Set cutoff distance approximately midway between the farthest target and the closest background" on page 4).

## Sensing Reliability 

For the highest sensitivity, position the target for sensing at or near the point of maximum excess gain. See the Performance Curves section for the excess gain curves. Maximum excess gain for model QS18VN6AF100 at a 20 mm cutoff occurs at a lens-to-object distance of about 7 mm, for example. Sensing at or near this distance makes 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: Reflective Background - Problem" on page 5). 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: Reflective Background - Solution" on page 5). 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: Object Beyond Cutoff - Problem" on page 5), 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: Object Beyond Cutoff - Solution" on page 5). 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.

Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400 nm to 700 nm, where eye protection is normally afforded by aversion responses, including the blink reflex. This reaction may be expected to provide adequate protection under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing. 

## Complies with IEC 60825-1:2014 and EN 60825-1:2014+A11:2021. 

Class 2 Laser Safety Notes . Low-power lasers are, by definition, incapable of causing eye injury within the duration of a blink (aversion response) of 0.25 seconds. They also must emit only visible wavelengths (400 nm to 700 nm). Therefore, an ocular hazard may exist only if individuals overcome their natural aversion to bright light and stare directly into the laser beam. 

## For safe laser use: 

- Do not stare at the laser. 

- Do not point the laser at a person’s eye. 

- Mount open laser beam paths either above or below eye level, where practical. 

- Terminate the beam emitted by the laser product at the end of its useful path.

## Product Support and Maintenance 

## Clean Sensor with Compressed Air Then Isopropyl Alcohol 

Handle the sensor with care during installation and operation. Sensor windows soiled by fingerprints, dust, water, oil, etc. create stray light that may degrade the peak performance of the sensor. 

Blow dust from the sensor using filtered, compressed air. If the sensor is still dirty, gently wipe the sensor with a dry optical cloth. If the dry optical cloth does not remove all residue, use 70% isopropyl alcohol on a clean optical cloth, then dry with a clean dry optical cloth and blow with filtered, compressed air. Do not use any other chemicals for cleaning.
