WLG4S-3P3232, Sick Retroreflective Photoelectric Sensor, Block Sensor, 5 m Detection Range

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
