SICK Background Suppression Photoelectric Sensor, Block Sensor, 25 mm → 300 mm, PNP, IP69K

Overview

At a glance

• Precise laser light spot, laser class 1
• Stainless steel housing with wash down design
• Latest SICK proprietary ASIC and laser technologies for outstanding background suppression and ambient light immunity
• Teach-in pushbutton can be switched between detection of transparent and tiny non-transparent objects
• ECOLAB certified, tested to IP 66, IP 67, IP 68 and IP 69K enclosure rating
• IO-Link (optional)

Your Benefit

• Precise laser light spot for highly accurate switching
• Washable stainless steel housing reduces bacterial contamination
• Innovative wash down design with sealed connections and unique patented membrane teach-in pushbutton
• High ambient light immunity reduces incorrect switching and ultimately machine downtime, even when modern energy-saving lights are used
• The 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 performance

For the best possible hygienic performance: thanks to high immunity to ambient light, the new W4SL-3 Inox Hygiene miniature photoelectric sensors with precise laser light spot set new standards when it comes to preventing undesired background reflections and to ambient light immunity, even with modern energy-saving lights. The combination of SICK's latest proprietary laser and ASIC technologies reduces incorrect switching to minimize machine downtime. The photoelectric sensors complete this product family. One device can reliably detect all transparent objects as well as tiny non-transparent objects, thus reducing the variety of devices. The photoelectric sensors also feature an IO-Link function, so that initial system performance diagnostics can be done independently. The W4SL-3 Inox Hygiene is certified in accordance with ECOLAB. In addition to an innovative leak-tight design, the sensors also have an impressive smooth housing design, which follows current hygiene guidelines.

Applications

• Precise object positioning – Detection of slices of sausage before primary packaging on a coarse-meshed, hygienic conveyor
• Precise edge detection – Controlling the exact position of ampulla-tubes before final closing
• Application are mostly in the pharmaceutical industry but also e.g. at the packaging, electronic and solar industry as well as food and beverage industry
