W4-3

Overview

Best-in-class sensing performance in a miniature housing

The W4-3 family of photoelectric sensors offers best-in-class performance in a miniature housing design. Using the latest ASIC and PinPoint LED technologies, these sensors provide reliable object detection of transparent and glossy objects like blisters, e-cards and aluminum cans. Optical axes on the flat side enable simple, space-saving integration in machine environments - even without mounting brackets.

At a glance
  • Best background suppression sensor in its class
  • Universal use of PinPoint 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 display thanks to IO-Link
