At a glance
• Precise laser light spot, laser class 1
• Latest SICK proprietary ASIC and laser technologies with second emitter LED to
provide outstanding background suppression and ambient light immunity
• Sensing range between 25 and 300 mm
• Established and proven housing design
• High-quality sensor manufacturing and testing for mechanical ruggedness
• Choice of adjustment via teach-in button, 5-turn potentiometer, or cable
Your benefits
• Precise laser light spot for highly accurate switching behavior
• High optical ambient light immunity reduces incorrect switching and thus machine
downtime, even when modern energy-saving lamps are used
• High-quality sensor manufacturing and testing reduce maintenance costs
• The highest degree of machine design flexibility and outstanding BGS
(background suppression) minimizes the effect of background reflections
• Established and proven housing design for easy installation
