Photoelectric sensors
W4SL-3, Photoelectric retro-reflective sensor, autocollimation

At a glance
• Precise laser light spot, laser class 1
• Long sensing range up to 12 m
• Autocollimation optics prevent blind spots
• Established and proven housing design
• High-quality sensor manufacturing and testing for mechanical ruggedness
• Choice of adjustment via teach-in button, 5-turn potentiometer, cable, or IO-Link

Your benefits
• Highly visible, even laser light spot with a sharp contour to facilitate alignment
• Sensing ranges between 0 and 12 m permit both short- and long-range use
• The highest degree of machine design flexibility. Autocollimation permits
   detection even through small drilled holes
• High-quality sensor manufacturing and testing reduce maintenance costs
• Established and proven housing design for easy installation
• IO-Link facilitates initial system performance diagnostics and uses additional
   sensor functions to reduce complex control programming
