Cut Sheet

Datasheet
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 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 pigtail 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.
Models
To order the 9 m (30 ft) cable models, add the suffix "W/30" to the cabled model number.
QD Models. For 4-pin integral Euro-style QD, add suffix “Q8” (for example, QS186EQ8). For 4-pin integral Pico-style QD,
add suffix “Q7” (for example, QS186EQ7). For 4-pin 150 mm (6 in) Euro-style pigtail, add suffix “Q5” (for example,
QS186EQ5). For 4-pin 150 mm (6 in) Pico-style pigtail, add suffix “Q” (for example, QS186EQ).
