The Banner QS18LLP Polarized Retroreflective Laser Sensor. This sensor is excellent for applications where high sensing power and small beam size are important. The QS18LLP uses a special filter to polarize the emitted light, filtering out unwanted reflections from shiny objects.

Features of the QS18LLP include:

• Visible Class 1 laser
• Narrow effective beam provides small-object detection and precise position control
• Crosstalk rejection algorithm protects against optical disturbance from adjacent sensors
• Excellent optical performance throughout sensing range, even close up
• 10 to 30V dc operation, with complementary (SPDT) NPN output
• Bright LED operating status indicators are visible
• Compact, rugged sealed housing, protected circuitry
• Mounting versatility - popular 18 mm threaded barrel or side-mount
