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
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.
