1 Lichtschranken W L- Laser photoelectric Baureihe WL switches - Photoelectric proximity switches, BGS Photoelectric reflex switches Through-beam photoelectric switches W L-: Laser photoelectric switches -- long-sighted, certainly, and no need for extra safety precautions TThe W L- series offers a complete range of photoelectric switches using innovative laser technology, contained in a rugged metal housing. Pulsed lasers are used to transmit light. Because they have in protection class, the machine operator does not need to take any extra safety or protective measures when using the sensors. All the devices in this series are particularly long-sighted : the WS/WE L- through-beam photoelectric switch covers distances up to 80 m, while the WL L- reflex photoelectric switch can reach up to 8 m. Their integrated polarisation filter makes it possible to reliably detect shiny surfaces. The WT L- photoelectric proximity switch also covers a relatively long range: it is the right choice for scanning fixed distances of mm, or offers precise background suppression that can be adjusted between 0 and 00 mm. In addition to the scanning range, the small dimensions of the light spot generated on the object is a further advantage of laser technology. This makes it possible to detect even minute items of just 0. mm at maximum switching frequencies of,00/s. W L- laser photoelectric switches the best solution for millimetre precision, or even smaller! 00 SENSICK CATALOGUE

2 W L- Laser n The laser photoelectric proximity switch detects minimal differences in height, such as overlapping metal sheets, during continuous metal production processes. b Moulded sheet-metal parts used for the production of automobiles are detected with millimetre accuracy by WL L- laser photoelectric switches so they can then be picked up and mounted with precision by a robot. n The W L- with laser technology detects the smallest electronic components with precision even at high switching frequencies. v Thanks to their small light spot, laser sensors such as the WT L- photoelectric proximity switch can also reliably detect the smallest objects such as packaging units in the pharmaceutical industry SENSICK CATALOGUE 0
