Model Name > WL11G-2B2531Part No. > 1041390
At a glanceRetro-reflective for detection of transparent objects•Robust sensors for industrial use•PinPoint technology is precise and fast-reacting for optimal detection of a verywide range of objects
•
Space-saving plastic housing in chemically, thermally or mechanically-resistantdesigns
•
Dovetail mounting - mounting holes and oblong holes for a very wide range ofsecuring options
•
All-round, easily visible status LEDs•Simple sensitivity control via potentiometer•
Your benefitsSuperior chip technology for reliable detection of objects, from PET bottles totransparent film. Effective suppression of optical interference factors from theindustrial environment
•
PinPoint technology for bright, small and precise light spot enabling fast andsimple sensor alignment
•
Precision switching characteristics and high standard of detection qualityguaranteeing universal detection of objects
