At a glance
• Retro-reflective with autocollimation principle
• Rugged housing designed to withstands harsh environments
• PinPoint LED technology with highly visible light spot
• Rugged die-cast zinc housing, optional Teflon® coating
• Dovetail mounting - mounting holes and oblong holes
• Highly visible status LEDs
• Sensing range adjustment via potentiometer
Your benefits
High immunity to ambient light and crosstalk ensures fewer false readings and less
downtime
Quick and easy setup due to highly visible PinPoint LED light spot
Highly visible status LEDs simplify sensitivity adjustments and reduce installation
time
Rugged metal housing (optional Teflon® coating available) requires fewer
maintenance costs due to its resistance to high-pressure cleaning
Increased reliability in harsh wash down environments
Easy installation using SICK accessories
