Overview The W4S-3 family of photoelectric sensors offers best-in-class performance in a slim housing design. Universal use of the latest ASIC and Pinpoint LED technologies provide maximum reliability in the detection of all objects, including transparent and shiny objects like blisters, e-cards and aluminium cans. Optical axes on the flat side enable simple, space-saving integration in the machine environment - even without separate mounting brackets. At a glance Best background suppression sensor in its class Universal use of Pinpoint LED technology in all models BGS proximity sensor with laser-like light spot for precise detection tasks Reliable setting via 5-turn potentiometer, teach-in pushbutton, teach-in via cable or IO-Link Flexible sensor settings, monitoring, advanced diagnostics, and visualization thanks to IO-Link Your Benefit Application versatility due to reliable detection of shiny, transparent or jet-black objects Very quick and easy alignment due to the highly visible, intense Pinpoint LED light spot Rugged mounting system with M3 threaded metal inserts reduces maintenance costs due to a long service life Background suppression sensors with a laser-like light spot reduce costs and installation of additional protective measures by replacing laser sensors IO-Link provides easy data access from the PLC Quick and easy configuration Quick and easy integration using function blocks Note Product details cover the whole product family.
