Polarized Retroreflective Laser Sensors
Features
• Visible class 1 laser with small, effective beam size
• Excellent optical performance throughout sensing range, even close up
• Easy push-button SET options: Maximum Excess Gain or Low-Contrast
SET, depending on model, plus Manual Adjust
• Easy-to-read operating status indicators, with 8-segment bargraph display
• Bipolar discrete outputs, PNP and NPN
• Selectable 30 millisecond OFF-delay
• Models available with 2 m or 9 m (6.5' or 30') cable or integral quick-discon-
nect
• Tough ABS housing rated IEC IP67; NEMA 6
• Compact housing, mounting versatility – popular 30 mm threaded nose or
side-mount
Excellent for applications where high sensing power and small beam size are important. Operates over sensing ranges typically accom-
plished only by conventional opposed-mode photoelectrics; uses a special filter to polarize the emitted light, filtering out unwanted reflec-
tions from shiny objects.

* 9 m (30 ft) cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., QS30LLP W/30). A model with
a QD connector requires a mating cable (see Quick-Disconnect Cables on page 10).
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.
