W4S-3 Inox

The W4S-3 INOX product family in WashDown design combines rugged watertight IP 69K stainless steel housing with “best-in-class” optical functionality.

These space-saving miniature sensors are able to withstand the most aggressive cleaning agents and disinfectants thanks to a membrane teach-in button that is 100% watertight and pin-cast M12 connections. They can be relied upon for long-term service in critical applications in the food and beverage, pharmaceutical, solar, and electronics industries.

Features

  • Tough stainless steel housing (316L/1.4404)
  • Resistant to a variety of common cleaning and disinfection agents
  • Highly visible laser-like light spot due to PinPoint LED
  • Teach-in via stainless steel pushbutton with a metal membrane
  • Flexible sensor settings, monitoring, advanced diagnostics, and visualization thanks to IO-Link
