• 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 ignoring objects in the background
• Background suppression models provide stable detection in the presence of fluorescent 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 plastic housings feature overmolded construction for superior robustness and sealing. 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 configuration 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 malfunction can cause either an energized or de-energized sensor output condition.

Applications Notes
1. Opposed mode sensor spacing can be reduced
by alternating emitters and receivers or by applying 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.
