Photoelectric sensors
W4S-3

Photoelectric sensor family with best-in-class performance

Your Benefits

  • 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

W4S-3

Overview

Photoelectric sensor family with best-in-class performance

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 aluminum 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
