High-power, infrared sensor for reliable 
detection of water and water-based liquids
The WORLD-BEAM® QS30H2O Sensor uses a 1450 nm sensing beam to burn through many types 
of thin-walled glass and plastic containers, creating contrast for reliable liquid detection. The 
QS30H2O Sensor is an innovative addition to Banner’s complete line of cost-effective, rugged and 
powerful WORLD-BEAM photoelectric sensors.
Liquid detection for challenging clear or translucent plastic or glass containers 
▶ 
  Emits light that water-based liquids will 
attenuate, enhancing contrast in 
challenging low-contrast applications 
▶ 
  Burns through many plastic and glass 
containers
▶ 
  Detects water-based liquids including 
liquor, beer, shampoos, conditioners, 
lotions and sauces
▶ 
  Penetrates many labels (material thickness 
and type dependent)
▶ 
 Features WORLD-BEAM QS30 housing 
with popular 30 mm threaded lens and 
side mount
▶ 
 Specified ranges of up to 4 m 
(longer range possible)
▶ 
 Offers built-in electronic crosstalk avoidance
▶ 
 Resists harsh environments with rugged IP67 
(NEMA 6) housing and encapsulated electronics
▶ 
Rated PW12 (1200 psi washdown)
▶ 
 Offers choice of 10 to 30V dc operation with 
bipolar, NPN (sinking) and PNP (soucing) output 
or 15 to 30V dc with analog (0-10V) output
▶ 
 Delivers highly visible power and output 
status indicators
▶ 
 Includes accessory apertures to attenuate 
or shape the beam
Versatile models 
to meet demanding 
requirements
▶ 
 Robust housing with 
30 mm threaded barrel 
and integrated side mount
▶ 
 Receivers with a choice of outputs 
and range
 • 
 Models with bipolar NPN/PNP output 
and 2 m range
 •
 High-gain models with bipolar 
NPN/PNP output and 4 m range
 •
 Analog (0-10V) output with 4 m range
▶ 
 Light operate (LO) or dark operate (DO), 
depending on model (discrete only)
▶ 
 Operating temperature from -20° to 60° C
▶ 
 Large output status indicator on back 
of receiver
▶ 
 Bright LED status indicators on sensor top
▶ 
 2 m or 9 m attached cable or 5-pin Euro-style 
pigtail quick-disconnect
