Baumer Electric: Photoelectric sensors
Said to be as reliable as a light barrier and as straightforward as a diffuse sensor, Baumer’s photoelectric sensors with the new SmartReflect principle provide object detection by creating a closed light beam between the sensor and machine part.
A separate reflector is unnecessary, reducing operating costs and increasing process safety. SmartReflect light barriers recognize objects of any kind.
FNDH and FNDR 14 SmartReflect light barriers in hygienic and washdown design are optimized for stainless steel surfaces. These EHEDG-certified sensors in stainless steel housing have a long range of 800 mm with reflection on stainless steel, making them useful for the 60-cm wide conveyor belts typically found in food processing. The elimination of the reflector as the weak spot ensures an increased process security. Thanks to the SmartReflect principle, the sensor function is not impaired by contamination or process-related changes of the machine part.
In adjustment mode, the sensor indicates when the received light signal is qualitatively best for reliable detection. This is especially useful with inclined surfaces and together with the comfortable one-point teach-in it saves time during installation.
