At a glance
• State of the art technology provides precise background suppression
• Withstands harsh environments
• PinPoint LED technology with highly visible light spot; variants available with IR
LED for highly critical applications
• Rugged die-cast zinc housing, with optional Teflon® coating
• Versatile mounting options due to dovetail mounting - mounting holes and oblong
holes
• Flexible sensing ranges and hysteresis settings
• Key lock function, remote teach, quality monitoring
• Diagnostics messages (contamination and short-circuit)
Your benefits
• State of the art technology, e.g. OES3 provides precise background suppression
and reliable detection of challenging objects
• High immunity to ambient light, optical reflections and crosstalk ensures fewer
false readings and less downtime
• Highly visible status LEDs simplify sensing distance adjustments and reduce
installation time
• A rugged metal housing withstands high-pressure cleaners and cleaning agents,
reducing downtime
• Complementary outputs in one housing reduce inventory and procurement costs
• IO-Link enables quick remote diagnostics and maintenance (optional)
• Easy installation using SICK accessories
