Overview The WLG4S-3 is a retro-reflective sensor enclosed in a slim housing that reliably detects transparent objects. Even small gaps between objects, highly transparent thin films, and vials with flow marks and severe lens defects can be reliably detected. Setting the sensor requires a single press of the teach-in pushbutton. The sensor reliably adjusts for any changes to environmental conditions such as temperature, dust or dirt. The single-lens autocollimation system “sees” through even the smallest of openings. The PinPoint LED's small but intense light spot enables quick and easy alignment even when using the smallest reflectors. Plus, variants with IO-Link provide continuous diagnostics data. At a glance Continuous threshold adaption of the switching threshold compensates for environmental changes Single-lens autocollimation optics Simple setting either via teach-in pushbutton, cable or IO-Link PinPoint LED technology with a small, highly visible, well-defined light spot enables high reserve levels when using small reflectors Flexible sensor settings, monitoring, advanced diagnostics, and visualization thanks to IO-Link Your Benefit Optimal detection of any kind of transparent object Quick and easy operation via the push of a button – automatic setting of the correct switching threshold Less downtime due to a Continuous Threshold Adaption which compensates for changing environmental conditions, including temperature, dust and drift effects The well-defined, highly visible intense light spot provides quick and reliable alignment IO-Link provides easy data access from the PLC Quick and easy configuration Quick and easy integration using function blocks Easy device replacement and identification Applications Tears in transparent films Note Product details cover the whole product family.
