Instruction Manual
Miniature Self-Contained Photoelectric Sensors in Universal Housing
•
Easily fits (or retrofits) almost any mounting situation
•
Exceptional optical performance, comparable to larger “MINI-style” or barrel sensors
•
10 V dc to 30 V dc operation, with complementary (SPDT) NPN or PNP outputs, depending
on model
•
Bright LED operating status indicators are visible from 360°
•
Rugged sealed housing, protected circuitry
•
Models available with or without 18 mm threaded “nose”
•
Less than 1 millisecond output response for excellent sensing repeatability
•
Choose 2 m (6.5 ft) or 9 m (30 ft) cable or 150 mm (6 inch) Pico-style cabled QD
WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or
death. This device 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.

•
To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, QS186E W/30.
•
To order the 4-pin M12/Euro-style integral quick disconnect model, add the suffix "Q8" to the model number. For example, QS186EQ8.
•
To order the 4-pin M8/Pico-style integral quick disconnect model, add the suffix "Q7" to the model number. For example, QS186EQ7.
•
To order the 150 mm (6 in) PVC cable model with a 4-pin M12/Euro-style quick disconnect, add the suffix "Q5" to the model number. For
example, QS186EQ5.
•
To order the 150 mm (6 in) PVC cable model with a 4-pin M8/Pico-style quick disconnect, add the suffix "Q" to the model number. For example,
QS186EQ.
•
Models with a quick disconnect require a mating cordset.
