Online Learning Contact a Banner Engineer About Your Application

Overview

  • High-performance sensing with visible Class 1 or Class 2 lasers, depending on model
  • Available in opposed, diffuse, retroreflective and adjustable-field sensing modes
  • 10 to 30V dc supply voltage with NPN or PNP output, depending on model
  • Long sensing ranges
  • Ideal for confined areas
  • Available with five beam shapes
  • Narrow effective beam for small object detection and precise position control
  • Bright LED status indicators with 360° visibility

Class 1 Laser Adjustable-field:Five-turn adjustment screw sets cutoff distance between 30 and 150 mm, clutched at both ends of travel
Class 2 Laser Adjustable-field:Five-turn adjustment screw sets cutoff distance between 50 and 250 mm, clutched at both ends of travel
ConstructionABS housing with acrylic lens cover. 2.5 mm (laser adjustable-field) and 3 mm mounting hardware is included with each sensor.
IndicatorsLaser Emitters, 1 LED indicator:
Green ON steady:power applied
All others, 2 LED Indicators:
Green ON steady:power ON
Green flashing:output overload
Yellow† ON steady:light sensed
Yellow† flashing:marginal excess gain (1.0-1.5x excess gain) in light condition
†Note::Prior to date code 0223, the output indicator was red instead of yellow.
