Lichtschranken W Photoelectric Baureihe switches WL - Photoelectric proximity switches, BGS Photoelectric reflex switches W : astering complex tasks reliably Through-beam photoelectric switches for temperatures ranging from to + C and polarising filters also make it possible to detect shiny surfaces. The scanning ranges of the W series speak for themselves: metres for the WS/WE through-beam photoelectric switch, metres for the WL photoelectric reflex switch and mm for the WT photoelectric proximity switch, which also offers adjustable scanning distance and background suppression. Great demands are often placed on the mechanical endurance of sensors. Suitable enclosure ratings (depending on the type of connection) of IP and IP, robust plastic housings, prefailure signalling output and indi- UUsers have long appreciated the benefits of the W series of photoelectric switches. Thanks to their design, the devices can be used both indoors and outdoors, since all DC types are suitable cator, and insensitivity to ambient light ensure reliable switching in hostile industrial environments. Universal voltage versions, time delay, test input and selectable light- or dark-switching are additional characteristic features of the W series. SENSICK CATALOGUE
