1 Lichtschranken W 8- Photoelectric Baureihe switches WL - Photoelectric proximity switches, BGS Photoelectric reflex switches Through-beam photoelectric switches W 8-: Integrated stateof-the-art technology for intelligent solutions Furthermore, the devices also incorporate a large number of features that are usually only found in special versions, e.g. the test input of the WS/WE 8- and WL 8-, the adjustable scanning distance with background suppression of the WTV 8-, individual plugs, or status LEDs as signal strength indicators, alignment aids, or prefailure signalling output. 0 SENSICK CATALOGUE TThe W 8- series of photoelectric switches is ideal for handling systems as well as for packaging machines and other complex tasks. WT 8- photoelectric proximity switches, WL 8- photoelectric reflex switches, or WS/WE 8- through-beam photoelectric switches thanks to their glass-fibre-reinforced and fully welded plastic housing, all of these sensors have the robustness required for industrial applications. Extremely large scanning ranges are an additional feature: up to 0 metres for the throughbeam photoelectric switch, up to metres for the photoelectric reflex switch and 00 mm or 00 mm for the photoelectric proximity switch (depending on whether a red light or infrared light source is used). The WTV 8- photoelectric proximity switch has been specially developed for and with the packaging industry. Its features include: its broad optical basis, internally adjustable optics, stateof-the-art electronics, powerful background suppression and optimised light spot geometry which together provide a previously unattainable level of immunity against ambient reflections. The detection of plastic bags on a conveyor belt, glossy and differently sized coffee packets or drinks cartons before being packed, cakes packed in plastic film on a stainless steel chain conveyor, or drinking straws attached to drinks containers all of these tasks can be mastered without any problem with the WTV 8-.

2 WL - W 8- m WTV 8- sensors used to check the presence of objects along the individual lanes of a packaging line for packs of coffee. b Transparency poses no problems: the WL 8- photoelectric reflex switch monitors the edges of packaging film. v Is the packaging unit complete? WT 8- photoelectric proximity switches provide us the answer. n Leak test for plastic bottles: WT 8- sensors used to check the presence of test objects in the automatic machine. SENSICK CATALOGUE
