Juli 2005 5:48 17 Photoelectric switch with built-in amplifier (long distance) in plastic housing E3G Retroreflective Models Sensing Distance of 10 m, with polar- ized light to detect shiny objects. Operation stability monitored ba the stability indicator. Distance-setting Models Distance setting models with a long 2m sensing distance incorporate a teaching function. Set sensing area (zone setting) func- tion allows detection of shiny objects with uneven surface. Common Features Meets IEC IP67 requirements.
