Green LED
(Power Indicator) Push Button
The Banner QS18 sensor is a high performance clear object detection
sensor with an IO-link and multifunction output. The polarized coaxial
optical design ensures reliable detection of transparent, translucent, and
opaque targets at any distance between the sensor and the reflector.
Low contrast sensing applications include PET bottles, glass containers,
and shrink wrap. The sensor can also be used to detect optical surfaces
such as: LCD panels with built in polarizing films, solar panels, and
semiconductor wafers.

2 Installation
2.1 Installing and Mounting the Sensor for Low Contrast Applications
Reliable transparent object detection depends on the sensor always detecting the object as "dark state" and the reflector
as the "light state". Using a recommended reflector, and proper orientation of the sensor to the reflector, is key to good
clear object detection. Optimize the reliable detection of transparent and clear objects by applying the following steps
when mounting the sensor and selecting a retroreflective target.
1. If a bracket is needed, mount the sensor onto the bracket.
2. Mount the sensor (or the sensor and the bracket) to the equipment at the desired location. Do not tighten at this
time.
3. Align the sensor's light spot to the middle of the retroreflector.
4. Mount the retroreflector perpendicular to the sensor optical axis (± 5°).
5. Tighten the screws to secure the sensor (or the sensor and the bracket) to the aligned position.
2.1 Mounting Considerations for Opaque Objects with Mirror Like Surfaces
To minimize the potential for reflections from mirror like objects affecting the sensor, it is best to side mount the sensor.

3 Sensor Configuration
Sensor configuration can be performed using IO-Link, the push button, or the remote input wire once enabled through IO-
link. Options include three sensing modes: Transparent, Film, and Opaque. Other configuration options include: output
delay timing, health output, offset percentages, and the ClearTracking auto compensation algorithm. For more detail, see
the IO-Link IODD package (p/n 198215), which includes an IO-Link Data Map, on the Banner Website at http://
www.bannerengineering.com.
3.1 Push Button Configuration
Use the push button to configure the sensor. Click the push button according to Push Button Input Flowchart. After a
configuration has been selected the sensor flashes both the green and amber LED to show which configuration was
selected followed by a rapid flashing of both the green and amber LED in unison to show acknowledgement and acceptance
of the configuration.

Enabling the remote input wire is done using IO-Link. Use the remote input function to configure the sensor remotely.
Connect the white wire of the sensor as shown in the wiring diagram. Pulse the remote line according to the Remote Input
Flowchart. After a configuration has been selected, both the green and amber LEDs will flash to show which configuration
was selected, followed by a rapid flashing of both the green and amber LED in unison to show acknowledgement and
acceptance of the configuration.

4.1 Transparent Mode Set
Use Transparent mode for low contrast applications where the object
is not present during the teach process. Transparent mode is the
default sensing mode and is best for most clear object detection
applications.
Example Applications For Offset Percentages
8% Recommended for very low contrast applications with stable
environmental conditions.
16% Recommended for most clear object detection applications in
typical machine industrial environments.
32% Recommended for high contrast detections such as brown or
green bottles, or opaque objects. This setting tolerates
environmental challenges such as vibrations and dust build-up.

1. Prepare the sensor.
Method Action Result

Remote Line Clear the light path to the reflector.
2. Access Transparent mode and set the sensing condition.
Method Action Result
Push Button Press and hold the button 2 to 4
seconds.
Transparent Mode Configuration Accepted
Green LED Indicator: Flashes 3 times.
Green and Amber LED Indicators: Acceptance Flash—
both LEDs flash 5 times rapidly in unison.
The sensor returns to Run mode with Transparent mode as
the sensing condition.
Transparent Mode Configuration Not Accepted
If there is not enough return signal the sensor will perform
an Opaque mode configuration indicated by:
Green and Amber LED Indicators: Flash 2 times.
Green and Amber LED Indicators: Acceptance Flash—
both LEDs flash 5 times rapidly in unison and the Green
LED will continue to flash.
The sensor is not ready for transparent detection due to
insufficient light from the reflector, but is ready for
maximum range Opaque object detection. Re-optimize
alignment, check the reflector size for required range, and
re-configure the sensor for transparent object detection.

4.2 Film Mode Set
Film mode is useful when the transparent target cannot be removed
from the light path during the teach procedure. This is common on
continuous web processes such as shrink wrapping machinery. The
sensor learns the dark state with the web present and switches the
output if the web breaks or runs out.
Example Applications For Offset Percentages
8% Recommended for very low contrast applications with stable
environmental conditions.
16% Recommended for most clear object detection applications in

environmental challenges such as vibrations and dust build-up.
