pigtail with a 5-pin Euro-style connector, add suffix “Q5” to the model number (e.g., QS30EH2OQ5). A model with a QD
connector requires a mating cordset (see Quick-Disconnect (QD) Cordsets on page 7).
** Standard emitters will only work with standard receivers. Super High-Power emitters will only work with Super High-Power receivers.
† Sensors can be used at ranges greater than listed for applications that require less excess gain. Please consult the

WARNING: Not To Be Used for Personnel Protection
Never use this product as a sensing device for personnel protection. Doing so could lead to seri-
ous injury or death. This product does NOT include the self-checking redundant circuitry necessary to
allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.
Overview
The Banner QS30H2O series water sensor was developed to detect the presence of water. Its electro-optical components are tuned to one absorption
band of water in the long infrared spectrum. The emitted infrared light penetrates many types of plastic and glass containers, but will not pass through
water-based fluids, nor through opaque substances such as wood, metal or
cardboard. Accessory apertures are available to attenuate or shape the beam
for low-gain applications, for example, clear water in a clear bottle.
Low-gain models are recommended for sensing applications where the liquid
container is transparent or when the thickness of liquid being detected is
small. Some examples are clear glass test tubes and clear PET beverage bottles. High-gain models are recommended when the liquid container is lightblocking (translucent) and when the thickness of liquid being detected is large.
Some examples are HDPE milk containers, colored PET beverage bottles,
and etched glass containers. Super High-Power models are recommended for
thick, opaque containers that require maximum burn-through power at a slower response speed.
For all applications, the sensors must be installed to maximize the optical contrast between the clear and blocked states. The installer can use apertures
and mechanical alignment of the sensors to achieve the best results (see
page 3). The QS30H2O sensor enhances the available contrast by taking advantage of the absorption band of water.

2 Output Conducting (Yellow, Discrete Mod-
els Only)
3 Receiver Power LED (Green)
4 AID Indicator (Yellow)
For advanced applications, a 0–10V analog output is available. The analog output allows the user to directly measure the amount of
signal attenuation. The analog output value can be filtered and a switching threshold determined in a PLC or computer as required for the
application. Please consult the factory for more information on using the analog output.
Each discrete output model has two bipolar outputs that switch simultaneously: one each NPN (sinking) and PNP (sourcing). Light Operate and Dark Operate models are available.
The versatile housing provides multiple mounting configurations in a minimum of space. These sensors are extremely rugged, powerful
and leakproof, with epoxy-encapsulated electronics for maximum resistance to mechanical shock and vibration. They are powerful
enough to burn through dust and many types of industrial and process contamination.
The sensors’ innovative circuitry provides excellent EMI/RFI noise immunity. For applications where optical crosstalk between multiple
sensor pairs may be a problem, either of two modulation frequencies may be selected. (Set each emitter to the same frequency as its
receiver, via the sensor hookup; see Figure 2. Sensor Alignment Procedure on page 3 or Hookups on page 7.)
Indicators
Each sensor has a green Power ON/OFF indicator, visible from 360° (see Figure 1). Receivers also have a yellow AID indicator that
flashes to show signal strength. (The higher the flash rate, the more light is received; a solid AID LED indicates excellent signal.) Discrete
models also have a large yellow LED that lights when an output is conducting.
Sensor Configuration
Teaching Limits
Discrete models require no configuration; simply align the emitter to the receiver to maximize contrast between the clear and blocked
conditions (see Figure 2. Sensor Alignment Procedure on page 3).

WORLD-BEAM QS30H2O Series
For analog models in high-contrast applications, alignment may be the only configuration needed. For more challenging applications using analog models, use the TEACH procedure to maximize contrast. This procedure is accomplished by pulsing the receiver’s white wire
(see Hookups on page 7 and teach procedure on page 4). Analog output slope also can be inverted from positive to negative or back.
Sensor Alignment — When Empty Container Can Be Presented
1. Position both the emitter and the receiver loosely in their mounting position. See Figure 2.
2. Present the “clear” condition for the application (an empty container).
3. Verify that both emitter and receiver are wired for the same
modulation frequency (see below).
4. Adjust the emitter first, then the receiver. Adjust the emitter’s position until the receiver AID indicator is ON steady, or is flashing
at its fastest rate.
5. Tighten the emitter mounting hardware, then repeat step 4 for
the receiver.
6. Block the sensor beam with the target and verify that the output
changes state.
Figure 2. Sensor Alignment Procedure
Sensor Alignment — When Empty Container Cannot Be Presented
For this procedure, the clear condition is no container at all.
1. Mount loosely and mechanically align the emitter and the receiver such that their faces are parallel to one another. (The AID indicator should be ON steady.)
2. Rotate the emitter in one direction until the receiver AID indicator begins to flash. Repeat in the other direction. Position the emitter
midway between those two positions and tighten the emitter mounting hardware.
3. Repeat step 2 for the receiver.
4. Block the sensor beam with the target and verify that the output changes state.
Frequency Selection
The modulation frequency (A or B) is selected by the state of the gray wire (on cabled models; pin 5 on QD models — see Hookups on
page 7). A “+” voltage or no connection selects frequency A; connecting it to “–” selects frequency B. Each emitter must be set to the
same frequency as its receiver.
Emitter Inhibit
To disable (or inhibit) the emitter LED (useful for testing the receiver operation), connect the white wire to “–” voltage.
Analog Static TEACH
Analog TEACH is performed remotely, by pulsing the white Teach wire (see
Hookups).
Restore Factory TEACH: Reverts the sensing limits to the factory default limits
(max contrast); output slope is not affected.
Analog Output Slope: Toggles the analog output to send a high signal when
object is absent (positive slope) or present (negative slope). Analog slope can
be selected based on the TEACH order (first taught condition is always 0V; second taught condition is 10V) or by using the slope select procedure below. If the
slope select procedure is used, it must be used after teaching the limits. To determine the current slope setting, measure the output signal during object
present and absent conditions.

Accessory Apertures
Opposed-mode QS30 sensors may be fitted with apertures to narrow or shape the sensor’s effective beam to more closely match the
size or profile of the containers being sensed. A common example is the use of slot type apertures to detect edges of liquid levels.
NOTE: The use of apertures will reduce the excess gain (see attentuation table below).

Examples for Apertures and Water Thickness vs. Excess Gain
The QS30EXH2O / QS30RXH2O sensor pair is used with a horizontal aperture model APQS30-040H on the receiver at 1 meter sensing
distance. The excess gain is reduced to approximately 200; 50 mm of water will completely block the signal.
When the same aperture is used on both the emitter and receiver at 1 meter, the excess gain is approximately 40; 35 mm of water
will block the signal.
NOTE: This example does not include the attenuation from the container holding the water.
