Overview
Slim photoelectric sensors reliably detect transparent objects
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
