Photoelectric sensors
W4SLG-3V, Photoelectric retro-reflective sensor, autocollimation

At a glance
• Precise laser light spot, laser class 1, no blind spots
• Stainless steel housing with washdown design
• Latest SICK proprietary ASIC and laser technologies for very good background
   suppression and ambient light immunity
• ECOLAB certified, tested to IP66, IP67, IP68 and IP69K enclosure rating
• Teach-in pushbutton can be switched between detection of transparent and tiny
   non-transparent objects
• IO-Link (optional)

Your benefits
• Precise laser light spot for highly accurate switching
• Washable stainless steel housing reduces bacterial contamination
• Innovative washdown design with sealed connections and unique patented
   membrane teach-in pushbutton
• High ambient light immunity reduces incorrect switching and ultimately machine
   downtime, even when modern energy-saving lights are used
• The highest degree of machine design flexibility. Outstanding BGS (background
   suppression) eliminates the effect of undesired background reflections.
   Autocollimation permits detection through very small drilled holes.
• IO-Link provides effortless initial diagnostics of system performance
