W 36 Photoelectric switches Lichtschranken Baureihe WL 27-2 Photoelectric proximity switches, BGS Photoelectric reflex switches W 36: Mastering complex tasks reliably Through-beam photoelectric switches electric 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 65 and IP 67, robust plastic housings, prefailure signalling output and indicator, and insensitivity to ambient U light ensure reliable switching in hostile industrial environments. Users have long appreciated the benefits of the W 36 series of Universal voltage versions, time photoelectric switches. Thanks to delay, test input and selectable their design, the devices can be light- or dark-switching are used both indoors and outdoors, additional characteristic features since all DC types are suitable of the W 36 series. for temperatures ranging from – 40 to + 55 °C and polarising filters also make it possible to detect shiny surfaces. The scanning ranges of the W 36 series speak for themselves: 60 metres for the WS/WE 36 through-beam photoelectric switch, 22 metres for the WL 36 photoelectric reflex switch and 800 mm for the WT 36 photo- 306 SENSICK CATALOGUE W 36 m Making sure that crates are full: WL 36 photoelectric reflex switches used to count coloured bottles before packaging. m WL 36 photoelec- tric reflex switches checking the presence of beer crates before automatic removal of the bottle caps. v WL 36 sensors used to detect mesh baskets in front of a goods lift. n Hot or cold, wet, dry or dusty – WL 36 photoelectric reflex switches are designed for use under hostile operating conditions indoors and outdoors – here they are being used on the roll-up gate of a carwash.
