OverviewAt a glancePrecise laser light spot, laser class 1Stainless steel housing with washdown designLatest SICK proprietary ASIC and laser technologies for outstanding background suppression and ambient light immunityTeach-in pushbutton can be switched between detection of transparent and tiny non-transparent objectsECOLAB certified, tested to IP 66, IP 67, IP 68 and IP 69K enclosure ratingIO-Link (optional)Your BenefitPrecise laser light spot for highly accurate switchingWashable stainless steel housing reduces bacterial contaminationInnovative washdown design with sealed connections and unique patented membrane teach-in pushbuttonHigh ambient light immunity reduces incorrect switching and ultimately machine downtime, even when modern energy-saving lights are usedThe highest degree of machine design flexibility. Outstanding BGS (background suppression) eliminates the effect of undesired background reflections. Autocollimation permits detection through very small drilled holes.IO-Link provides effortless initial diagnostics of system performanceFor the best possible performance in a wet environment: thanks to high light immunity, the new W4SL-3 Inox miniature photoelectric sensors from SICK with precise laser light spot set new standards when it comes to preventing undesired background reflections and to ambient light immunity, even in modern energy-saving lights. The combination of SICK's latest proprietary laser and ASIC technologies reduces incorrect switching. The photoelectric sensors complete this product family. One device can reliably detect all transparent objects as well as tiny non-transparent objects. This reduces the variety of devices and saves on storage costs. The photoelectric sensors also feature an IO-Link function, so that initial system performance diagnostics can be done independently. The W4SL-3 Inox is certified in accordance with ECOLAB. The membrane teach-in pushbutton and the pin-cast electrical connections make it reliable even in critical ambient conditions.ApplicationsPrecise object positioning – Detection of slices of sausage before primary packaging on a coarse-meshed, hygienic conveyorPrecise edge detection – Controlling the exact position of ampulla-tubes before final closingApplication are mostly in the pharmaceutical industry but also e.g. at the packaging, electronic and solar industry as well as food and beverage industryNoteProduct details cover the whole product family.
