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
PinPoint LED technology provides a highly visible light spot that enables quick and
easy sensor alignment
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
