WORLD-BEAM® Q20 Series Sensors
Compact, Self-Contained Family of Sensors
Features
• Photoelectric sensors in a compact, rugged, sealed, over-molded plastic housing
• Standard 3 mm threaded mounting holes on 25.4 mm (1") spacing
• Advanced electronic design for excellent noise immunity and cross-talk avoidance
• Threaded metal M8 connector on Pico-style quick-disconnect models
• 10 to 30V dc operation with complementary solid-state outputs (1 normally open, 1
normally closed); PNP (sourcing) or NPN (sinking), depending on model
• Complete offering of mounting brackets and apertures available
• Crosstalk prevention filters available for visible red opposed mode pairs
• Exceptional optical performance with easy to align visible red emitters
• Background suppression models provide reliable detection up to 150 mm while ignor-
ing objects in the background
• Background suppression models provide stable detection in the presence of fluores-
cent lights
Overview
Banner’s Q20 family of sensors offers a full complement of sensing modes, with
the excellent performance expected of much larger sensors. Their compact plas-
tic housings feature overmolded construction for superior robustness and seal-
ing. Their popular rectangular design is easy to mount into tight spaces; integral
threaded mounting holes eliminate the need for separate mounting nuts.
The single-turn Gain potentiometer on most models and bright LEDs (positioned
on top of the housing for 360° visibility) provide easy alignment and configura-
tion for reliable sensing (see Figure 1. Features on page 1).
WARNING: Not To Be Used for Personnel
Protection
Never use this product as a sensing device
for personnel protection. Doing so could
lead to serious 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 malfunc-
tion can cause either an energized or de-ener-
gized sensor output condition.

• For 4-pin Pico-style (threaded) integral QD, add suffix “Q7” (e.g., Q20EQ7).
• For 4-pin Pico-style (threaded) 150 mm (6") pigtail QD, add suffix “Q” (e.g., Q20EQ).
• For 4-pin Euro-style 150 mm (6") pigtail QD, add suffix “Q5” (e.g., Q20EQ5).
• For 150 mm (6") PUR pigtail cable with 4-pin threaded Euro-style QD connector, add “QPMA” to model number (e.g., Q20EQPMA)
† Range is specified using a model BRT-84 reflector.

Applications Notes
1. Opposed mode sensor spacing can be reduced
by alternating emitters and receivers or by ap-
plying cross talk filters (visible red models only)
2. NPN off-state leakage current is <200 µA for
load resistances > 3kΩ or optically isolated
loads. For load currents of 100 mA, leakage is
<1% of load current.
